HIGH-PRESSURE PUMP FOR A FUEL-INJECTION DEVICE OF AN INTERNAL COMBUSTION ENGINE

A high-pressure pump having a rotationally driven drive shaft with a shaft portion embodied eccentrically to its axis of rotation, on which shaft portion a ring is rotatably supported. At least one pump element, has a pump piston, driven at least indirectly in a reciprocating motion by the drive sha...

description A high-pressure pump having a rotationally driven drive shaft with a shaft portion embodied eccentrically to its axis of rotation, on which shaft portion a ring is rotatably supported. At least one pump element, has a pump piston, driven at least indirectly in a reciprocating motion by the drive shaft via the ring and resting at least indirectly on the ring. The ring is provided, at least on its outer face facing away from the shaft portion, with a coating of a friction-reducing paint in at least one region, in which the at least one pump piston rests at least indirectly on the ring.
