Abstract

A piston pump for an electronically controllable vehicle brake system including a particularly simple, inexpensive, and space-saving throttle, and a filter hydraulically upstream of it, which prevents the throttle from becoming clogged with impurities. The pressure fluid outlet is routed at least partway along the circumferential surface of the bushing and, in the region of this section, the filter and throttle are embodied in one piece with the circumferential surface of the bushing.
