<P>PROBLEM TO BE SOLVED: To stably operate an ejector type refrigeration cycle even with a change in the flow rate of a driving flow that passes through a nozzle of an ejector. Ž<P>SOLUTION: A refrigerant outlet of a suction side evaporator 16 is connected to the refrigerant suction port 13b side of the ejector 13, and a second compression mechanism 21a is provided between the suction side evaporator and the refrigerant suction port 13b of the ejector 13. Consequently, even in such operating states that the suction capacity of the ejector 13 is deteriorated with a fall in the flow rate of the driving flow of the ejector, the suction capacity of the ejector 13 can be assisted by the second compression mechanism 21a. The ejector type refrigeration cycle can thereby be stably operated even with the change in the flow rate of the driving flow. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
