INTERNAL COMBUSTION ENGINE WITH ORBITAL PISTON
The reason I invented this engine is to be different from other engines
especially rotaries
where they have the rotor solid on a shaft. This one is floating on the shaft.
One would
ask, how can it turn the shaft if it floats? When mounted off center it floats
from the
crank. When it turns it has the same principle as a connecting rod with no rod
and no
seals on the piston crown. It rolls around the cylinder wall with little
friction. As it turns,
it elongates the pressure area and you have three times the cubic inch as a
piston engine
and with 90 degree more turning torque. It would be more fuel-efficient than
existing
engines. Light in weight, easy to manufacture and single design, the piston is
cooled with
outside air. There are no special seals or rings and needs very little
lubrication that can be
put in the fuel or oil injection. It fires on every second revolution. The
compressor pumps
on each revolution so that the compressor can be regulated to the desired
ratio and can
easily be adapted to diesel fuel. I know of no other engine with so many
advantages.
As a unit consistent of two units; one for combustion, one for compression
mounted on
one shaft turning in the same direction and fires on every second revolution
while turning
around the cylinder wall. The principles are the same as any recipitating
engine but there
is no connecting rod, the piston is mounted to the shaft with a roller bearing
mounted off
center on the main shaft. As the piston turns it puts a pressure on the
bearing that turns
the shaft that has a special key that compensates the pressure on the cylinder
wall. Air
that feeds the compressor is taken through the end plate and piston for
cooling.
A housing "A", represents the orbital engine. Within the housing comprises a
cylindrical
wall "B". Air starts the compressor, "R", shown in figure three which is
located outside
the housing and feeds into a rotating valve "W" then into combustion chamber
"J". At
the base of housing "A" is a base oil pan "N". Within the combustion chamber
"J" is a
gate valve "I" having at one end a wrist pin, "P". A spark plug "M" fits into
cylinder head
"H" and locates itself within the combustion chamber "J". Head bolts "Q" are
located on
either side of the combustion chamber "J" and extend through said cylinder
head "H" and
into housing "A". The cylinder piston "C" surrounds the bearing "D". The

"C" is connected to the shaft "F". The cooling ports "0" surround the inner
wall of the
piston and the outer wall of the bearing. The intake port "K" feeds into the
combustion
chamber and the exhaust port "L" extends through the inner wall of housing "A"
and the
outer wall of said housing.
When ignited, pressure opens valve "I" as the piston "C" turns on the bearing
"D",
combustion pressure puts force on piston "C" that puts force on the bearing
"D" that
turns the shaft "F" as the piston "C" turns it elongates the compression area
"J" 270
degrees to the exhaust port "L". The next revolution the gate valve "I" stays
closed to
recharge for the next revolution.
