Patent ID: 7938230

Claim:
A device for lubricating a component in an assembly of parts, the device comprising a lubricant distribution chamber arranged in the vicinity of the component, wherein said chamber is formed by an annular groove in an outer surface of a ring mounted on two inner cylindrical bearing surfaces of one of the parts of said assembly, said inner cylindrical bearing surfaces having different diameters and being interconnected by a radial surface, wherein the ring comprises two annular grooves, located respectively upstream and downstream from the annular groove forming the chamber, said upstream and downstream annular grooves housing gaskets cooperating respectively with said two cylindrical bearing surfaces of the part, wherein said annular groove forming the chamber is closed by the inner cylindrical bearing surface of greater diameter and by said radial surface interconnecting said two inner cylindrical bearing surfaces, and wherein a first duct is formed in said part and opens out into the inner cylindrical bearing surface of greater diameter for feeding the groove with lubricant and a second duct being formed in said part and opening out into said inner cylindrical bearing surface with said greater diameter for taking lubricant from the groove to the component.
