Hydraulic unit for slip-controlled brake systems

摘要

The present invention relates to a hydraulic unit for slip-controlled brake systems which includes a third row of valves in the accommodating member between a first row of valves having the valve-accommodating bores for the inlet valves and the second housing surface, wherein the third row of valves includes at least in one valve-accommodating bore an electric change-over valve which is closed in its basic position and hydraulically linked to the pump-accommodating bore by way of a portion of a suction channel that traverses the first row of valves for connection to the pump-accommodating bore.
