    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: In a heat pump apparatus of the invention, a refrigerant is circulated through a compressor 31, a radiator 32, a first throttle apparatus 33, a heat exchanger 34, a second throttle apparatus 35 and an evaporator 36 in this order. The heat exchanger 34 can be utilized as both a radiator and an evaporator by operating the first throttle apparatus 33 and the second throttle apparatus 35. Therefore, even if the outside air temperature is high, discharge pressure and suction pressure of the compressor do not rise, the heat pump apparatus can be operated in a stable refrigeration cycle, and energy can be saved.
