Abstract

A device for damping pressure pulsations, in electronically regulatable vehicle brake systems for damping the pressure pulsations that are caused by pressure generators in a hydraulic circuit connected to it. The device has a housing which encloses a damping chamber and also has at least one hydraulic connection opening into the damping chamber, and a throttle device. The housing and throttle device are embodied as a compact damping unit that can be preassembled, is economical, and can be anchored in only a few work steps to the hydraulic block of an electronically regulatable vehicle brake system.
