Abstract

A valve of a piston pump for a vehicle brake system having a closing body which is resiliently preloaded against a sealing seat. The closing body is formed in two parts with a damping piston and a closing element inserted therein. The damping piston is axially displaceably guided in a cylindrical piston guide. At least one flow channel is provided between the damping piston and the piston guide. The at least one flow channel is configured such that fluid can flow around the damping piston in the longitudinal direction thereof through the at least one flow channel.
