ABSTRACT:
In an ejector-type depressurizer, a nozzle arrangement converts pressure energy of refrigerant supplied from a radiator into velocity energy to depressurize and expand the refrigerant, and a pressurizer arrangement mixes the refrigerant discharged from the nozzle arrangement with the refrigerant drawn from an evaporator and converts the velocity energy of the refrigerant discharged from the nozzle arrangement into pressure energy to increase the pressure of the mixed refrigerant discharged from the pressurizer arrangement. The pressurizer arrangement includes a refrigerant passage that conducts the refrigerant supplied from the nozzle arrangement and the refrigerant supplied from the evaporator, and the refrigerant passage includes a refrigerant passing zone, through which the refrigerant from the nozzle arrangement and the refrigerant from the evaporator mainly pass during operation of the ejector-type depressurizer. A cross sectional size of the refrigerant passing zone of the refrigerant passage is variable.
