    摘要： An integrated unit for a refrigerant cycle device includes an ejector having a nozzle part for decompressing refrigerant, and an evaporator located to evaporate the refrigerant to be drawn into a refrigerant suction port of the ejector or the refrigerant discharged from an outlet of the ejector. The evaporator includes a plurality of tubes defining refrigerant passages through which refrigerant flows, a tank that is disposed at one end side of the tubes for distributing refrigerant into the tubes and for collecting the refrigerant from the tubes. The tank extends in a tank longitudinal direction that is parallel to an arrangement direction of the tubes, and is provided with an end portion in the tank longitudinal direction. Furthermore, the end portion has a hole portion for inserting the ejector, and the ejector is inserted into an inner space of the tank from the hole portion.

    摘要： An ejector-type air-conditioning and refrigerating system according to the present invention is mounted on an automotive vehicle. The system includes a first evaporator for cooling a passenger compartment and a second evaporator for cooling a refrigerator mounted on the vehicle. Refrigerant is supplied to the first evaporator through an ejector, while the refrigerant is supplied to the second evaporator through a restrictor disposed in a branch passage. Refrigerant evaporated in the second evaporator is sucked by a sucking portion provided in the ejector through a sucking passage. A noise dissipater for suppressing noises caused by pulsating vibrations generated in the ejector is disposed in the sucking passage at a position close to the sucking portion of the ejector. The noise dissipater is postured in the sucking passage so that liquid components in the refrigerant including oil contained in the refrigerant are prevented from being retained in the dissipater.
