摘要： An integrally formed vane (301) is disposed slidably in a vane groove (205a) of a first cylinder (205) and a vane groove (206a) of a second cylinder (206). A cut-out (301a) with a width substantially equal to the thickness of an intermediate plate (304) is provided in the vane (301), which is divided by this cut-out (301a) into a first vane portion (301b) whose leading end makes contact with a first piston (209) at its leading end and a second vane portion (301c) whose leading end makes contact with a second piston (210). This configuration allows the first vane portion (301b) to be pushed toward the first piston (209) side by the pressure difference acting on the second vane portion (301c) and makes it possible to keep a contact state between the first vane portion (301b) and the first piston (209), even when no pushing force toward the first piston (209) side that results from the pressure difference acts on the first vane portion (301b).

摘要： A refrigerating machine includes a compressor for compressing a refrigerant, a radiator for radiating heat from the refrigerant discharged from the compressor, an expander for expanding the refrigerant discharged from the radiator, and an evaporator for evaporating the refrigerant discharged from the expander, all connected in series. The refrigerating machine also includes a refrigerant flow regulator for regulating the amount of refrigerant flowing into the expander and a controller for controlling the compressor and the refrigerant flow regulator. When the compressor is stopped, the controller controls the refrigerant flow regulator to reduce the amount of refrigerant flowing into the expander.

摘要： The present invention provides a heat pump including: a compressor; a radiator; a first throttling device having a variable opening; an expander; a second throttling device having a variable opening; an evaporator; piping that connects the compressor, the radiator, the first throttling device, the expander, the second throttling device, and the evaporator so that refrigerant circulates thorough the elements in that order; and a control device for controlling the opening of the first throttling device and the opening of the second throttling device. This heat pump is capable of independently controlling the pressure of the refrigerant flowing into the expander (intermediate pressure) and pressure in a high-pressure side of a refrigeration cycle, and also is capable of size reduction, or in some cases elimination, of a receiver for the refrigerant.
