English Abstract





The subject of this invention is an ocean wave air compressor that produces
variable flows, by using
the perpetual, clean, abundant and renewable energy of the sea waves. This
compressor uses the
force of the waves and the hydrostatic pressure of water in order to admit and
compress air in an
adjustable compression chamber where any waves' height is useful. The said
compressor can be
mounted in addition on pylons in the middle of seawater, where levelling means
are used to lower or
higher it during high and low tides. Air is compressed when the wave hits the
compressor and water
is admitted inside the compression chamber, and atmospheric air is admitted
for the next cycle when
the water recedes out of the compressor. The resulting compressed air is
collected in a pressure tank
to be used later to run a power plant such as that described in CA patent no
2328580.

Ocean Wave Hydraulic Air Compressor.
This invention relates to the con struction of an ocean wave hydraulic air
compressor that uses the
perpetual, clean, abundant and renewable energy of sea waves.
The subject of this invention is a hydraulic-like compressor; that uses the
perpetual, clean, abundant
and renewable energy of sea waves in order to admit and compress variable
volumes of air. This
compressor uses a compression chamber that replaces the cylinder, and the
seawater that replaces
the piston of conventional compressors. In addition the present ocean wave
hydraulic air compressor
eliminates specially the use of non-renewable energy while ensuring ease of
operation, efficiency
and the conservation of energy.
The embodiment of this invention includes the following:
1- A container turned upside dov~rn, where its bottom-opening is connected to
a wide open mouth,
that faces the open sea in order to contain completely any size of sea waves,
while permitting them
to hit hard, that allows seawater to flow inside the container propelled by
inertia and hydrostatic
pressure in order to compress and push out of the said compressor any
imprisoned volume of air
inside the said container that is called the compression chamber. The said
mouth is made in a way to
let the waves hit and be direct to 'the inside of the compressor, and it is
used in addition of seawater
inlet during the air compression cycle, for the seawater outlet during
atmospheric air admission
when the wave recedes and the sf;awater retreats out of the compression
chamber of the said ocean
wave hydraulic air compressor.
2- Air inlet and outlet valves that are located at the higher end of the
container, allow only
atmospheric air to enter during the air admission cycle through the inlet
valves while the outlet
valves are blocked, and compressed air to exhaust during the compressed air
exhaust cycle through
the outlet valves while the inlet valves are blocked.
3- A variable compression chamber allowing the compressor to produce variable
flows according to
the height of the sea waves during high or low seas. The said container is
made out of two telescopic
parts, an upper first part that is mobile and a lower second part that is
stationary. The upper end of

CA 02499018 2005-03-10
the mobile first upper part is closed and houses the air inlet and outlet
valves, while its bottom is
open enough to let it overlap and slide over the stationary second lower part
that permits the creation
of a variable volume inside the compressor in order to admit and compress a
right volume of air
according with the waves height and energy.
4- A seal that is located between the mobile first upper and the stationary
second lower parts of the
compressor in order to create a tight joint between them, which prevents any
air leak at this point
during the air compression cycles..
5- Levelling means such as hydraulic cylinders or the like, to higher or lower
the mobile first upper
part of the compressor in order to variate the inside volume of the
compression chamber that
determines the admitted volume of atmospheric air.
6- Float means that prevent seawater from going beyond the air outlet valves
at the end of the
compression and the exhaust cycle of compressed air. These float means are
optional.
7- Seawater collection means that hold any seawater crossing beyond the
compressed air outlet
valves, that help to collect and purge any seawater accumulation from the
compressed air's system.
8- Shock absorber means that can be fixed on the compressor's mobile first
upper part levelling
means, in order to absorb the violent hits of the sea waves on the upper end
of the compression
chamber at the end of the compressed air cycles.
9- Other levelling means for the entire compressor, combined with long pylons
that are affixed on
the sea-bed in order to hold the entire compressor fare from shore at the
right level according to high
and low tides for a better harness of the perpetual, clean, abundant and
renewable energy of the sea
waves.
The compressed air produced by this type of ocean wave hydraulic air
compressors will be used to
run power plants of the sort of the Canadian patent no 2460452.

upward or downward the said mobile first upper part 2 according to waves'
height.
3- The location of the compressor is chosen in order to determine the length
and the size of the
needed pylons 31 that are affixed to the sea floor 40.
4- The entire compressor is mounted on the said pylons 31 offshore through its
levelling device that
includes the brackets 36 that are affixed to the beams 32 that in turn are
affixed to the pylons 31, the
brackets 37 that are affixed to the compressor it self and in turn are affixed
to the pistons 34 of the
hydraulic cylinders 33, the sliding brackets 38 that are in place in the
guiding grooves 39 of the
pylons 31 that are used to guide the entire compressor during its levelling
procedures while holding
it firmly against the repeated hits and the force of the waves.
5- The line 9 of the compressed air is connected to the rotary transfer joint
18-A of the power plant
E of the Canadian patent no 2460452 in order to transfer the compressed air
from the compressor to
the power plant E.
6- The power plant E is built according to the specifications of the Canadian
patent 2460452 in order
to function with the fluctuated flows that are produced by the ocean wave
hydraulic air compressor
the subject of the present invention.
Operation of the invention.
Once all of the components are irk place, the ocean wave hydraulic air
compressor is ready to run.
1- according to high or low tides, the compressor's levelling device's sensor
determines constantly
the level of the seawater then the order goes to the hydraulic cylinders 33 to
position the
12

CA 02499018 2005-03-10
compressor's mouth 1 at the right level, and the compressor waves height's
sensor determines
constantly the height of the waves, then the order goes to the hydraulic
cylinders 4 to position the
compressor's mobile first upper part 2 that creates the right volume for the
compression chamber in
order to harness the maximum amount of energy that helps to produce the
maximum air flow
according to every situation.
2- figure 5 shows the compressor in place at the surface of the seawater
during high sea, and the
wave's height is previously determined by the compressor's sensor that
commands the hydraulic
cylinders 4 to lift the mobile first upper part 2 of the compressor to create
the right volume that can
be filed exactly with seawater when the wave hits. In addition figure 5 shows
the end of the air inlet
cycle when the wave receded to the lower level the seawater can retreat to.
While retreating, the
seawater is evacuated from the compressor back to the sea through the large
mouth 1, and
atmospheric air is admitted inside the compression chamber through the inlet
air valve 14 in order to
accelerate the evacuation of the seawater, then, when the level of the
seawater riches the bottom end
3-A of the stationary second lower part 3, a communication is established at
this point between the
inside of the compressor and the atmosphere while a bigger quantity of
atmospheric air enters the
compressor in order to fill up completely the compression chamber with the
needed atmospheric air
for the following compression cycle.
3- Figure 6 shows the end of the <;ompressed air cycle during high sea. When
the next wave hits, the
seawater is pushed to enter the compressor through the mouth 1 while
compressing the imprisoned
air and pushing it out of the compressor through the outlet valve 15 and the
line 9 to go to an air
tank or directly to the power plant E figure 21 of the Canadian patent no
2460452.
4- Figure 12 shows the compressor in place at the surface of the seawater
during low sea, and the
wave's height is previously determined by the compressor's sensor that
commands the hydraulic
cylinders 4 to lower the mobile first upper part 2 of the compressor to create
the right volume for the
compression chamber that can be filed exactly with seawater when the wave
hits. In addition figure
12 shows the end of the air inlet cycle when the wave receded to the lower
level the seawater can
retreat to. The same thing happens as for high sea, While retreating, the
seawater is evacuated from
the compressor back to the sea through the large mouth l, and atmospheric air
is admitted inside the
compression chamber through the inlet air valve 14 in order to accelerate the
evacuation of the
13

CA 02499018 2005-03-10
seawater, then, when the level of the seawater riches the bottom end 3-A of
the stationary second
lower part 3, a communication is established exactly as in figure 6 during
high sea, and bigger
quantity of atmospheric air enters the compressor in order to fill up
completely the compression
chamber with the needed atmospheric air for the following compression cycle.
5- Figure 13 shows the end of the compressed air cycle during low sea. When
the next wave hits,
The same thing happens as for high sea, the sea water is pushed to enter the
compressor through the
mouth 1 while compressing the imprisoned air and pushing it out of the
compressor through the
outlet valve 15 and the transmission line 9 to go to an air tank or directly
to the power plant E figure
20 of the Canadian patent no 2461)452.
6- If the compressor is equipped with float means, the float 21 is built in a
way to float at the surface
of the seawater that enters the float housing 22 through the drillings 24 and
its upper surface 23 fits
snugly with the opening 2-A where the compressed air exits through the
compressed air outlet valve
15 at the end of the compressed air exhaust cycle where the seawater is not
permitted to go beyond
this limit.
7- If the compressor is equipped with seawater collection means that hold any
seawater crossing
accidentally beyond the air outlet valves 15 to the air compressed
transmission line 9, the water 27
enters the container 25 while the compressed air continues its way toward the
air tank or toward the
power plant E of the Canadian patent no 2460452. In addition the air system is
equipped with
sensors that help to purge the collected seawater out of the container 25
through the purge valve 26.
8- If the compressor is equipped with Shock absorber means 20 that can be
fixed on the
compressor's mobile first upper I>art's levelling means in order to absorb the
accidental violent hits
of the sea waves on the upper end 2-A of the compression chamber when the
seawater hits hard
accidentally, that means when all of the compressed air of the present cycle
is already pushed out of
the compressor and the seawater still have some inertia. In order to protect
the compressor from
being damage, the hard hit is absorbed by the spring 29 while the mobile first
upper part 2 is pushed
upwardly and the entire compressor stays in place without being affected.
Finally after the hit the
mobile first upper part 2 returns to its original position to be ready for the
next compression cycle.
