Abstract

The invention relates to a reciprocating piston pump for delivering a liquid. The pump includes a solenoid with an actuator and an outlet port. A check valve with a seat body is assigned to the outlet port for keeping a return flow of the liquid out of the reciprocating piston pump. The seat body bears an impact damping face at a front face facing away from a valve seat of the check valve, and the valve seat of the check valve and the impact damping face are made from the same elastomer material.
