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： A compressor includes orbiting and non-orbiting scroll members meshingly engaged to form a series of compression pockets, including first pockets when the orbiting scroll member is in a first position. A first porting in the non-orbiting scroll member communicates with the first pockets during a portion of a compression cycle. The first pockets include a set of radially outermost pockets located radially inward relative to the first porting and isolated from communication with the first porting during the compression cycle. The first porting is aligned with a spiral wrap of the orbiting scroll member at a location radially outward from and directly adjacent the first pockets when the orbiting scroll member is in the first position. Additional porting communicates with each of the compression pockets located radially outward relative to the first pockets when the orbiting scroll member is in the first position.

The outlet volume 400 is substantially bounded between the outlet port, the first rotor, the second rotor, and the interior chamber of the housing. The transfer volume 500 is substantially bounded between the first rotor, the second rotor, and the interior chamber of the housing. The bleed port 600, 600′, 1600 is adapted to fluidly connect the outlet volume and the transfer volume at least during a portion of a transfer volume cycle. The variable bleed port may include a plate that pivots about a pivot or slides along a slide. The plate may be arc shaped and may arc around a centerline of one of the rotors. The plate may be positioned within an operating cavity. The operating cavity may be defined within the housing between a bearing plate and a main housing of the housing. A method of supercharging an internal combustion engine includes bleeding a transfer volume to an outlet volume through a bleed port.
