摘要： A claw pump includes: a housing which forms a pump chamber; two rotating shafts which are disposed parallel to each other inside the housing; a pair of rotors which are respectively fixed to the two rotating shafts inside the housing and are provided with hook-shaped claws meshing with each other in a non-contact state; a rotary drive device which drives the pair of rotors so as to be rotated; and a suction port and discharge ports which are formed in a partition wall of the housing. The discharge ports are constituted by a first discharge port and a second discharge port, the first discharge port is formed at a position that communicates with an initial stage compression space formed at an initial stage of a compression stroke in a compression space that is formed by joining a first pocket and a second pocket defined by the pair of the rotors and the partition wall of the housing, and the second discharge port is formed at a position that communicates with an end stage compression space formed at an end stage of the compression stroke in the compression space. The claw pump includes an opening/closing mechanism which opens the first discharge port when a pressure of the initial stage compression space reaches a threshold of atmospheric pressure or higher and closes the first discharge port when the pressure of the initial stage compression space does not reach the threshold.

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： In a gas compressor, an outline shape of an inner peripheral surface (41) of a cylinder (40) is set such that in a point before a compression chamber (43B) adjacent to a compression chamber (43A) in the upstream side in the rotational direction (W) is exposed to a discharge hole (45b) of a primary discharge portion (45) with rotation of a rotor (50) in the rotational direction (W) (point where the compression chamber (43B) is positioned upstream of an angular position of being exposed to the discharge hole (45b) of the primary discharge portion (45)), a pressure of the refrigerant gas (G) inside the compression chamber (43) reaches a discharge pressure. Therefore the discharge hole (45b) of the primary discharge portion (45) always discherges a refrigerant gas (G) from the compression chamber (43) to prevent generation of the discharge pulsation.
