FIELD: engine manufacturing.
SUBSTANCE: invention relates to engine manufacturing. A device (200) for lubricating the contact surface (17) of a cam (16) rigidly connected in rotation to a camshaft (14) installed rotatably in a motor vehicle heat engine, while the specified shaft (14) contains a longitudinal oil supply channel (30), as well as a radial discharge port (22). The cam has a side wall opposite the discharge port (22) containing a feed device (100) designed to direct the oil along the cam wall to the contact surface (17). At the same time, the feed device (100) contains an oil collecting cavity (19). The camshaft and heat engine of the motor vehicle are also disclosed.
EFFECT: invention is aimed at ensuring the delivery of oil to the contact surface of the cam with a pusher.
