Piston Pump for a Vehicle Brake System

摘要

A piston pump for a vehicle brake system includes a piston which is mounted in a cylinder so as to be movable along an axis. An inlet valve for introduction of fluid into the cylinder, and a sealing element configured to seal off the piston with respect to the cylinder are located on the piston. A first portion of the piston includes a valve seat of the inlet valve, and a second portion of the piston includes a piston rod. The sealing element includes a projection which engages axially over the first piston portion and extends to the second piston portion.
