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.

摘要： A mode changing apparatus for a scroll compressor is provided that may include a low-pressure passage that communicates with a suction side, an intermediate-pressure passage that communicates with an intermediate-pressure side, a block assembly mounted at the fixed scroll and having a connection channel that connects the low-pressure passage and the intermediate-pressure passage, a switching device disposed at the block assembly that opens/closes the connection channel, and a pressure supply device that selectively applies, to the block assembly, a discharge gas pressure discharged from the fixed and orbiting scrolls and a suction gas pressure sucked into the fixed and orbiting scrolls, to thereby operate the switching device.

摘要： Un dispositif de pompage à vide selon l'invention comprend un moteur (1) entraînant une pompe mécanique sèche (2) multi-étagée dans laquelle les étages (5, 6, 7, 8) sont connectés successivement en parallèle puis en série, selon plusieurs configurations successives que l'on choisit chacune pour optimiser le débit de pompage dans la plage de pression en cours. Cela permet de descendre rapidement la pression dans une enceinte (100), tout en réduisant d'environ 40 % le volume de la pompe et l'énergie consommée par rapport à une pompe traditionnelle de débit suffisant pour atteindre la même rapidité de pompage.
