Abstract

A hydraulics block having a piston-cylinder unit that can be driven by an electric motor via a gear in order to generate a brake pressure for a hydraulic non-muscular-energy vehicle brake system. An annular cavity is provided which encloses a piston of the piston-cylinder unit inside a cylinder, as a leakage chamber which communicates with a reservoir. Possible drag leakage is carried away in this manner. An end shield situated between the electric motor and the gear prevents lubricant or leakage from entering the electric motor.
