Abstract
A piston pump housing for a hydraulic pressure generator in a vehicle brake system includes a housing, in which a bore for receiving an eccentric shaft is formed. In the housing at least six cylinders for receiving one pump piston each are further provided. The cylinders are disposed in pairs in three or more mutually spaced-apart planes and open out in each case into the receiving bore for the eccentric shaft. According to a possible realization, in a two-circuit vehicle brake system at least three cylinders are associated with each brake circuit to increase the operating comfort. To reduce wear, each of the provided eccentrics interacts with only two pump pistons.
