AnRefrigerant flow rate control devicenfor anEjector refrigerant cycle systemncontainsnan ejector pump (15, 31, 33) having a nozzle section (16) for decompressingna refrigerantna first stream of a branching section (A), a first onenEvaporator (20) for vaporizing the refrigerant discharged from the ejector;na throttle element (21, 25, 27, 30) for decompressing the refrigerantna second stream of the branching section, one downstream ofnThrottle element and upstream of a refrigerant suction port (17b)nthe ejector arranged second evaporator (22) and an adjustment mechanismn(19) having a temperature-sensitive deformation element (19d),nthat is according to a changena refrigerant temperaturenof the circular system to form a refrigerant passageway (Anoz,nAe) of the nozzle sectionnand adjust the throttle device. The adjustment mechanismnmay be provided to a flow rate ratio (η) one throughnthe nozzle sectionnthe ejector decompressed refrigerant flown(Gnoz) and one into the refrigerant suction port ofnEjector pump sucked refrigerant flown(Ge). |
