Device for maintaining a constant oil level

Claim 3

A device according to claim 1, wherein said constant level reservoir (1) and said reserve reservoir (12) are made of an optically transparent material.

Claim 4

The device according to claim 1 wherein said constant level reservoir has a cover (3), and the device comprises a unidirectional breather valve (5) fitted within said cover.

Claim 5

A device according to claim 1 wherein in said duct means a tap (13) is located for controlling the flow in said duct means.

Claim 6

A device according to claim 1, wherein said float means comprises a lever (34) pivoted to a valve body housed within the said constant level reservoir (1), the said lever (34) having at one end a bell float (35) and at the other end a cam portion (33) acting on an actuating rod (32) in contact at its upper end with valve shutter balls (24) in contact with a valve shutter seat (23) formed in correspondence with the connector (10) for the said communication duct (11), said bell float moving downwardly when the oil level in the constant level reservoir falls below a predetermined valve and causing said actuating rod and said shutter balls to rise whereby oil is introduced from said reserve reservoir into said constant level reservoir.

Claim 7

A device according to claim 1 wherein said constant level reservoir has at the bottom an elbow connector (16), connected by means of connection duct (18) to a side arm (19a) of a T-connector (19) connected to the bottom of said oil sump.

Claim 8

A device according to claim 6 wherein said T-connector (19) has a second side arm (19b) in communication with a discharge duct (40), said duct having its free end fixedly connectable to the upper part (41) of said oil sump (20).

Claim 9

A support for a device for maintaining constant the level of oil in an internal combustion engine, said internal combustion engine having an oil sump, the device comprising a constant level reservoir (1), a duct (15) connecting said constant level reservoir to the bottom of the sump whereby the level within the sump is maintained at the level in the constant level reservoir, a reserve reservoir (12) positioned at a level higher than the constant level reservoir, duct means (11) for placing said constant level reservoir in communication with said reserve reservoir, float means (21) in said constat level reservoir for controlling flow in said duct means, said support comprising a substantially U-shape bracket (50) connectable to the vertical arm (60) of a mounting frame (61), the mounting frame (61) being provided with a horizontal arm (62) for fixing to said oil sump (20), said support bracket (50) being operable to support the said constant level reservoir (1), said bracket having two horizontal arms, (51) and (52), a vertical panel connecting said two horizontal arms, said bracket being fixed at a predetermined level onto said vertical arm.

Claim 10

A support for a device for maintaining constant the level of oil in an internal combustion engine, said internal combustion engine having an oil sump, the device comprising a constant level reservoir (1), a duct (15) connecting said constant level reservoir to the bottom of the sump whereby the level within the sump is maintained at the level in the constant level reservoir, a reserve reservoir (12) positioned at a level higher than the constant level reservoir, duct means (11) for placing said constant level reservoir in communication with said reserve reservoir, float means (21) in said constat level reservoir for controlling flow in said duct means, said support comprising a substantially U-shape bracket (50) connectable to the vertical arm (60) of a mounting frame (61), the mounting frame (61) being provided with a horizontal arm (62) for fixing to said oil sump (20), said support bracket (50) being operable to support the said constant level reservoir (1), said bracket having two horizontal arms, (51) and (52), a vertical panel connecting said two horizontal arms, said bracket being fixed at a predetermined level onto said vertical arm.

Claim 11

The support according to claim 8 wherein said vertical arm is provided with elongate slots (64), said vertical panel has a plurality of opening, (54), said slots (64) being disposed in correspondence with the openings (54).

Claim 12

The support according to claim 8 wherein said bracket (50) has on its upper arm (51) a hole (55) for housing a connector for said communication duct (11) and a notch (56) for receiving said breather valve (5), the lower arm (52) having a recess (57) for receiving said elbow connector (16).
