Abstract
A refrigerant flow-amount controlling device for an ejector refrigerant cycle system includes an ejector having a nozzle for decompressing refrigerant of a first stream of a branch portion, a first evaporator for evaporating refrigerant flowing out of the ejector, a throttle member for decompressing refrigerant of a second stream of the branch portion, a second evaporator disposed downstream of the throttle member and upstream of a refrigerant suction portion of the ejector, and an adjusting mechanism having a temperature-sensitive deformation member that is deformed in accordance with a variation in a refrigerant temperature of the cycle system to adjust one refrigerant passage area of the nozzle portion and the throttle means. The adjusting mechanism can be provided to adjust a flow ratio of a refrigerant amount decompressed by the nozzle portion of the ejector and a refrigerant amount drawn into the refrigerant suction port of the ejector.
