    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: The expander-compressor unit 70 includes the closed casing 1, the expansion mechanism 4 disposed in the closed casing 1 so that a surrounding space thereof is filled with the oil, the compression mechanism 2 disposed in the closed casing 1 so as to be positioned higher than the oil level, the shaft 5 for coupling the compression mechanism and the expansion mechanism 4 to each other, and the oil flow suppressing member 50 disposed in the surrounding space of the expansion mechanism 4 so that the space 55a filled with the oil is formed between the expansion mechanism 4 and the oil flow suppressing member 50. Thereby the flow of the oil filling the inner reserving space 55a is suppressed, and thus, heat transfer from the high temperature oil to the low temperature expansion mechanism can be reduced.
