摘要： In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, a variable throttle device is disposed upstream from the nozzle to decompress and expand high-pressure refrigerant flowing from a condenser. For example, the variable throttle device decompresses the high-pressure refrigerant in a gas-liquid two-phase state at an upstream position from the nozzle of the ejector. In addition, the variable throttle device includes a back pressure chamber having an inner pressure that changes by sensing a refrigerant temperature at a refrigerant outlet side of an evaporator, and a pressure introducing means for introducing a refrigerant pressure of a refrigerant outlet side of the evaporator to a side opposite to the back pressure chamber with respect to a diaphragm. Therefore, a pressure difference between the back pressure chamber and the side opposite to the back pressure chamber can be made smaller.

摘要： In an ejector cycle with an ejector including a nozzle for decompressing refrigerant, an insulation member is provided on an outer surface of the ejector to suppress a heat exchange with an external side. When a suction portion of the ejector is insulated by the insulation member, pressure loss in the suction portion can be reduced, a gas refrigerant ratio at an inlet port of the mixing portion can be reduced, and a liquid refrigerant amount to be supplied to the evaporator can be increased. In addition, when a mixing portion and a diffuser portion of the ejector are insulated, it can prevent liquid refrigerant from being excessively evaporated. As a result, it can effectively restrict heat loss due to a heat exchange in the ejector with the external side.

摘要： In an ejector, a nozzle is provided within a housing to defining a passage portion around the nozzle, and a suction port is provided in the housing to draw a refrigerant by entrainment of a driving refrigerant jetted from the nozzle. Further, a wall portion is provided in the housing such that the refrigerant drawn from the suction port into the passage portion is prevented from flowing toward an inlet side of the nozzle from a position of the suction port in an axial direction of the nozzle. Therefore, all of the refrigerant flowing from the suction port flows toward an outlet side of the nozzle without flowing toward the inlet side of the nozzle from the position of the suction port in the axial direction. Thus, it can prevent a large pressure loss from being caused in the refrigerant sucked from the suction port, and ejector efficiency can be effectively increased.
摘要翻译： 在喷射器中，喷嘴设置在壳体内以限定喷嘴周围的通道部分，并且吸入口设置在壳体中以通过夹带从喷嘴喷射的驱动制冷剂来吸入制冷剂。 此外，在壳体中设置有壁部，使得从吸入口向通道部分中抽出的制冷剂不会从喷嘴的沿喷嘴轴向的位置流向喷嘴的入口侧。 因此，从吸入口流出的所有制冷剂从吸入口的轴向位置向喷嘴的入口侧流向喷嘴的出口侧。 因此，可以防止从吸入口吸入的制冷剂中产生大的压力损失，能够有效地提高喷射器的效率。

摘要： A body part of a decompression device has a swirl space for swirling a refrigerant that flows from a refrigerant inlet, and a refrigerant outlet that is positioned on an extension line of a swirl center line of the refrigerant and functions as a throttle. Further, a passage cross-sectional area of the refrigerant inlet is configured to be smaller than a twelve-fold value of a passage cross-sectional size of the refrigerant outlet, such that a swirl speed of the refrigerant in the swirl space is increased so as to enable a decompression boiling of the refrigerant around the swirl center line. In such manner, a gas-liquid mixture phase refrigerant securely flows into the refrigerant outlet, and it restricts a fluctuation of a flow amount of the refrigerant flowing toward a downstream side without complicating a cycle structure.
