ABSTRACT:
A device for lubricating the cams of camshafts of reciprocable piston engines according to which oil under pressure is supplied to circumferential and axial grooves provided in the bearing or bearings for the camshaft. From the axial groove or grooves oil is intermittently sprayed upon a selected surface of the cam or cams of the camshaft. To this end, the axial groove is radially spaced from the central axis of the camshaft, and intermittently at a certain circumferential angle relative to a selected surface portion of the cam, for instance the active elevated cam portion, oil under pressure is sprayed from the axial bore onto the selected cam surface to be lubricated.
