Abstract
A pump receiver housing of a hydraulically operated pressing apparatus designed in a compact and lightweight manner and that connects a drive unit to a piston cylinder unit and to a press unit. A piston pump assembly is connected to a pump flange pressed directly onto a connection cylinder of the piston-cylinder unit. The connection cylinder projects through a pump lead-through in the housing wall into the pump receiver housing, and directly contacts on the pump piston. Thus, the pump receiver housing is designed without conduits, so that an inside of the pump receiver housing is free of or has no high pressure.
