摘要： A refrigerant cycle device having an ejector includes a first evaporator for evaporating refrigerant flowing out of the ejector, a first passage portion for guiding refrigerant to a refrigerant suction port of the ejector, a throttle unit located in the first passage portion, a second evaporator located in the first passage portion downstream of the throttle unit, a bypass passage portion for guiding hot gas refrigerant from a compressor into the second evaporator, a bypass opening and closing unit provided in the bypass passage portion. Furthermore, a second passage portion is branched from the bypass passage portion downstream of the bypass opening and closing unit, and a flow control unit is provided in the second passage portion to prevent a flow of refrigerant from the first evaporator to the second evaporator through the second passage portion. Therefore, defrosting of both the first and second evaporators can be suitably performed.

摘要： An ejector device includes a nozzle having an inner wall surface defining a circular cross-sectional fluid passage extending from an inlet to a jet port. Furthermore, the fluid passage has a throat portion at a position between the inlet and the jet port, and a passage expanding portion in which the cross-sectional area of the fluid passage is enlarged from the throat portion as toward downstream. The passage expanding portion includes a middle portion in which the inner wall surface is expanded in a fluid flow direction by a first expanding angle, and an outlet portion from a downstream end of the middle portion to the jet port, in which the inner wall surface is expanded in the fluid flow direction by a second expanding angle that is larger than the first expanding angle. The ejector device can be suitably used for a refrigeration cycle apparatus.

摘要： A housing is configured into a tubular form and receives at least a portion of an ejector functional unit, which includes a nozzle and a body. A housing side opening radially penetrates through an outer peripheral wall surface and an inner peripheral wall surface of the housing and communicates with the fluid suction opening of the body. The housing side opening is adapted to join with a suction opening side external device, through which the fluid is drawn into the fluid suction opening.
