Module with an electric generator and a pump unit

Abstract

A module preferably to be used in a machine tool or a machine, in particular in a fork lift truck, has an electric generator and a pump unit, both of which can be powered by an internal combustion engine. The pump unit is located at least partly in an axial recess of the generator housing and is provided to cool the generator. To expand the range of potential applications of the module, the pump unit is a hydraulic pump adapted to supply at least one hydraulic system. The housing of the pump consists of the walls of the generator housing that form the recess and a pump cover that creates a fluid-tight closure for the recess of the generator housing. The pump cover has a suction connection that empties into the recess of the generator housing. At least one distributing valve is integrated at least partly into the pump cover and/or at least one distributing valve is attached to the pump cover. The hydraulic pump is preferably an axial piston pump employing the swash plate principle, and the pump cover is a control base receptacle of the axial piston pump.
