摘要

The piston pump (1), especially for the fluid for a non-skid vehicle brake system, has at least one piston (5) and a pressure valve (11) at a valve cartridge (7) with a pressure spring (16) and a valve closure body (15). A non-rotating lock is at the spring (16), near the body (15), with at least one projection aligned towards the body (15).
