Pump combination

摘要

A vacuum pump designed as a vane cell pump and a hydraulic pump designed as a radial piston pump are combined into one construction unit. They are driven by coupling to the camshaft (37) of a motor vehicle motor (21). The rotor of the vane cell pump is on one side taper bore mounted on the side facing the motor vehicle motor and exhibits there the coupling counterpart (35) to the camshaft. On the opposite side the rotor has a coupling part, which corresponds to that of the camshaft. On this side the connection flange (24) of the vacuum pump is identical to the connection flange of the motor. <IMAGE>
