摘要： PROBLEM TO BE SOLVED: To improve a performance coefficient of a refrigeration cycle device by reducing pressure loss when discharging a cooling medium from a compressor.SOLUTION: By controlling throttle opening of an expansion valve 3 for intermediate pressure of a refrigeration cycle device configuring a gas injection cycle, pressure of an intermediate pressure cooling medium flowing into a compression chamber from an injection port 1b is adjusted in such a manner that a cooling medium pressure in the compression chamber becomes closer to a pressure of a cooling medium on a high pressure side Pd of the cycle, when the compression chamber of a compressor 1 communicates with a discharge port 1c. Thereby, backflow of the cooling medium on a high pressure side into the compression chamber via the discharge port 1c can be suppressed, and a check valve for a discharge port can be eliminated. Therefore, a performance coefficient of a refrigeration cycle device can be improved by reducing pressure loss when discharging a cooling medium from the compressor.
摘要翻译：要解决的问题：通过减少从压缩机排出冷却介质时的压力损失来提高制冷循环装置的性能系数。解决方案：通过控制构成气体的制冷循环装置的中间压力的膨胀阀3的节气门开度喷射循环，从喷射口1b流入压缩室的中压冷却介质的压力被调节成使得压缩室中的冷却介质压力变得更接近于高压侧Pd上的冷却介质的压力当压缩机1的压缩室与排出口1c连通时。由此，可以抑制高压侧的冷却介质经由排出口1c向压缩室的回流，能够消除排出口的止回阀。因此，通过减少从压缩机排出冷却介质时的压力损失，可以提高制冷循环装置的性能系数。

摘要： PROBLEM TO BE SOLVED: To provide an oil separator capable of suppressing degradation of oil separation efficiency, and reducing an energy loss, regardless of the flow rate change of fluid flowing into the inside.SOLUTION: On an oil separator equipped with a cylindrical container 41 formed with a plurality of coolant flowing inlets 41a making a coolant mixed with oil flow in, and a swiveling space 41b the fluid mixed with the oil flowing in from the coolant flowing inlets 41a, a reed valve 43 is provided, which increases one coolant passage area of the plurality of coolant flowing inlets 41a with the increase of a flow rate of the coolant flowing into the cylindrical container 41. Therefore, when the flow rate of the coolant flowing into the cylindrical container 41 is increased, the increase of a pressure loss is suppressed to reduce an energy loss. When the flow rate of the coolant flowing into the cylindrical container 41 is decreased, the lowing of the flowing speed of the coolant swiveling in the swiveling space 41b is suppressed to suppress the degradation of oil separation efficiency.
