Abstract

A hydraulic unit for a motor vehicle brake system operating on the recirculation principle, in which each brake circuit has in the region of the hydraulic unit a prefilling location which opens into the pump suction conduit between the pressure-retaining valve and the change-over valve for the purpose of receiving brake fluid. The hydraulic unit can thereby be prefilled with lower complexity and cost in terms of time and processes prior to installation in the vehicle.
