An ejector type refrigerating cycle comprises a compressor, a heat radiating device, an ejector, and a first vaporizing device, which are connected in a circuit to form a refrigerating cycle. A bypass passage is provided between an inlet port and a suction port of the ejector, so that a part of the refrigerant is bifurcated to flow through the bypass passage. A second vaporizing device is provided in the bypass passage. An internal heat exchanger is further provided between an outlet side of the heat radiating device and the inlet side of the ejector, so that the enthalpy of the high-pressure refrigerant from the heat radiating device is reduced, to thereby increase an enthalpy difference between the inlet side and outlet side of the first and second vaporizing devices. As a result, the cooling capability by the both vaporizing devices can be improved.
