Abstract
In a drive unit which includes an electric motor and a cooling fan as well as a hydraulic power steering pump to be driven by the electric motor, the cooling fan is operatively connected to the motor by a clutch and a control circuit is provided for operating the clutch so as to disengage the cooling fan whenever the power steering unit needs hydraulic fluid for steering assistance, whereby both, the cooling fan and the hydraulic pump, are never operated at the same time so that the motor may be relatively small, light and inexpensive.
