Abstract

The discharge of a variable displacement wobble plate compressor is varied by selectively controlling the pressure prevailing in the crankcase of the device. The duty cycle of a signal controlling the pressure is determined in accordance with the ambient air temperature, the temperature required in the cabin and pressure prevailing in the evaporator.
