An ejector equipped refrigeration cycle for an automotive air conditioner, which is reduced in costs and uses an ejector comprises a variable displacement compressor which is driven by the vehicle engine. The compressor capacity is controlled by a capacity control valve 2 until the difference between the discharge pressure Pd and the suction pressure Ps is determined by an external signal, e.g. for the valve 2. The control of the compressor differential pressure also controls the ejector differential pressure. A differential pressure valve 9 between a gas-liquid separator 7 and an evaporator 10 is set to a value proportional to the ejector differential pressure. The value is determined from the external signal. <IMAGE> |
