Abstract

A piston pump for a slip-controlled hydraulic brake system for a vehicle. A tubular filter is mounted on a bush of the piston pump; the filter has a filter ring that forms a guide ring and is spaced apart from the bush and axially guides the piston by a part of the piston that protrudes from the bush. A separate guide ring is dispensed with, and the structural length of the piston pump can be shortened.
