Hydraulic unit for a motor vehicle

摘要

A hydraulic unit for a motor vehicle consisting of a housing comprising two housing chambers separated by a wall located inside the housing, in which a reciprocating pump is supported by the wall located inside the housing and is arranged in a first housing chamber which forms a hydraulic fluid reservoir. A drive member for the reciprocating pump is led out of the first housing chamber. A nonreturn valve provided in the wall located inside the housing establishes a fluid communication from the reciprocating pump to a pressure chamber in the second housing chamber, which is separated from a gas pressure reservoir also provided in the second housing chamber by a reservoir piston guided in the second housing chamber.
