Abstract

A hydraulic unit for an electronically slip-controllable power brake system of a motor vehicle. A cuboidal housing block is equipped with components for generating a braking pressure and for open- or closed-loop control thereof. On a motor side of the housing block, a motor is fastened to drive a braking pressure generator, while on a reservoir side, a reservoir is provided to supply the vehicle brake system with a pressure medium. The reservoir has at least one protruding fastening peg, which projects into a recess open to the outside on the housing block. Using a retaining pin inserted into a transverse bore of the housing block and passing through this recess, the reservoir is anchored to the housing block. The transverse bore, open on the motor side of the housing block, is in a flat portion in which a pin head of the retaining pin lies without the pin head protruding axially beyond a motor side of the housing block.
