INDICATEUR DE NIVEAU D'HUILE

OIL LEVEL INDICATOR

Abrégé anglais

The invention is the oil level indicator that is used for the oil level
control in the closed
space of mechanisms and vehicles. The main component of the invention is the
light
reflecting material which is placed behind the display (control) window.
The light reflecting from the mirror surface, allows for determining the oil
level in the
mechanism with any degree of oil contamination.

Description
Oil level indicator
The invention possesses numerous benefits and advantages over known oil level
indicator. The
existing methods of oil controls are rather labourious. The presently used
display window that is
made of transparent material is imperfect in a way that it enables the oil
control only at early stage
of the oil change in a mechanism. Over the course of the operation of
mechanism, the oil darkens
gradually making it difficult or even impossible to see and detennine the oil
level.
What contrasts the invention from the existing oil level control methods is
that under the new
method, a light-reflecting window gets installed inside the display window
within 10 mm. This
provides a clear reflection of oil level in a mechanism.
The example of practical application of the invention can be its usage in the
wheel hub of
commercial transportation devices. Presently existing display windows are
extremely ineffective.
Oil absorbs the light and determination of its level becomes unfeasible. The
untimely note of
insufficient oil level leads to deterioration of the hub bearing that in turn,
may lead to catastrophic
consequences, such as loss of the wheel during the transport operation.
The hub oiler cap (Element 1 of Figure 1) of a commercial transportation
vehicle is shown in the
attached drawing (Figure 1). A light-reflecting screen (Element 4 of Figure 1)
is installed inside the
hub oiler cap within 10 mm from the display window (Element 2 of Figure 1).
With the presently
used oil control window, the only way to determine if the oil is present in
the hub or check the oil
level, is to open the tap (element 3 of Figure 1) and manually check the oil
level by hand.
Although the invention has been described in connection with a truck hub, it
should be understood
that various modifications additions and alterations may be made to the
invention by one skilled in
the art without deporting from the spirit and scope of the invention as
defined in the appended
claim.
