    摘要: A method of and an apparatus for effecting volume control suitable for use with a compressor for compressing a compressible fluid, such as a refrigerant of the refrigeration cycle, wherein a suction fluid is forcedly closed while a suction step is being performed and the fluid drawn up to then by suction into each working chamber is subjected to adiabatic expansion during the rest of the suction stroke. The fluid in the working chamber subjected to adiabatic expansion is then subjected to adiabatic compression in initial stages of a compression stroke following the suction stroke only for a period corresponding to the period of the adiabatic expansion. An on-off control valve (12) is mounted in a fluid suction passage (1e 2,10b) and operative to be brought, when it is necessary to effect volume control, to a closed position while the suction stroke is being performed, to thereby interrupt the flow of the fluid through the fluid suction passage (10b) to the working chamber.

    摘要: A rotary-vane type fluid machine is constructed such that a rotor (1) is caused to rotate within a casing (2) to increase or decrease the volume of a space created between the outer periphery of the rotor (1) and the inner wall surface of the casing (2) by vane structures (8) which rotate together with the rotor (1) to thereby transfer a fluid by pressure in accordance with the variation in volume of said space. The vane structure (8) has two vanes disposed in substantially symmetrical relationship with respect to a shaft (6) of the rotor and fixed so that they can not moved relative to each other. The fluid machine also comprises a crank mechanism (3, 4, 3a, 4a) which causes the vane structure (8) to radially advance the retreat in order to reciprocally vary a distance between a center of the shaft (6) and a tip end (7) of one vane and a distance between the center of the shaft (6) and a tip end (7) of the other vane in accordance with the rotation of the rotor (1).
