Abstract

The pump has a pump piston (20) that is indirectly supported in a drive shaft by a hollow cylindrical tappet (40). The tappet is displaceably guided in a bore (42) of a part of a base plate (14) in a direction of the longitudinal axis (21) of the piston. The tappet has a groove (56) running in the direction of a longitudinal axis (41) of the tappet. A ball (58) is indirectly fixed in a part of the plate in a tangential direction to the tappet and is engaged in the groove approximately radial to the longitudinal axis (41). A rolling friction exists between the ball and the tappet.
