摘要

Fuel pump (20) comprises an actuating device (36) for opening a valve element (56) of an inlet valve (32) during suctioning of a conveyor piston (40). Preferred Features: The position of a lift stop (74) for the valve element can be influenced by the actuating device. The actuating device comprises a sleeve (70) which moves coaxially and axially to the inlet valve and contains a spring plate (66) of the inlet valve. The sleeve has an end surface forming the lift stop.
