Patent ID: 7832229

Claim:
An integrated unit for a refrigerant cycle device, comprising: an ejector having a nozzle portion for decompressing refrigerant, and a refrigerant suction port from which refrigerant is drawn by a refrigerant flow injected from the nozzle portion, the ejector being configured for mixing the refrigerant injected from the nozzle portion and the refrigerant drawn from the refrigerant suction port and for discharging the mixed refrigerant therefrom; an evaporator for evaporating the refrigerant to be drawn into the refrigerant suction port or the refrigerant discharged from the ejector, the evaporator and the ejector being integrally assembled, wherein the evaporator includes a plurality of tubes for allowing the refrigerant to flow therethrough, and a tank extending in a longitudinal direction that is substantially parallel to a direction of arrangement of the tubes, the tank being configured to distribute the refrigerant into the tubes or collect the refrigerant flowing from the tubes; a plug for sealing an insertion hole that is provided in a longitudinal end surface of the tank such that the ejector is inserted from the insertion hole to be located in the tank; a spacer configured to have a gap between the plug and the ejector; and a fixing member, disposed between the longitudinal end surface of the tank and an expansion valve for decompressing the refrigerant, for fixing the expansion valve to the longitudinal end surface of the tank, wherein at least one of the fixing member, the plug, and the spacer is formed of a resin material.
