摘要： It is an object of the present invention to improve the efficiency of a scroll gas compressor by operating a bypass at a proper compression ratio. To achieve the object, the present invention is constituted so that at least one pair of bypass holes whose one ends are opened in a compression chamber currently performing compression nearby a discharge vent and whose other ends communicate with a discharge chamber are asymmetrically arranged on a panel board. This structure makes it possible to improve the efficiency of the compressor by operating the bypass at an optimum compression ratio even if a difference is observed between pressure rises of a pair of symmetric compressed spaces under the compression process.

摘要： A scroll compressor has a check valve assembly for selectively opening and closing a discharge port and allowing a fluid to flow only from the discharge port towards a discharge chamber. A stationary end plate mounted in the scroll compressor has a plurality of bypass holes defined therein at locations symmetrical in terms of pressure. The plurality of bypass holes are open to compression chambers closest to the discharge port and communicate with the discharge chamber. The stationary end plate also has at least one bypass valve for selectively opening and closing the bypass holes and allowing the fluid to flow only from the compression chambers towards the discharge chamber through the bypass holes. The bypass holes are serviceable to prevent an excessive compression and are positioned so as not to be closed by an orbiting scroll wrap immediately after the compression chambers closest to the discharge port have communicated with the discharge port.

摘要： A scroll compressor comprises a generally cylindrical casing and stationary and orbiting scrolls both accommodated in the casing. The stationary and orbiting scrolls engage with each other to define a plurality of compression chambers therebetween. The orbiting scroll is driven by a drive shaft which is in turn supported by a frame having a thrust bearing formed thereon. One of an orbiting end plate of the orbiting scroll and the thrust bearing has an annular groove defined therein in which an annular seal member is received. The orbiting scroll is disposed between the stationary scroll and the frame with an axial gap defined therebetween. First, second, and third back chambers are formed on the opposite side of the compression chambers with respect to the orbiting end plate. The first and second back chambers are partitioned by the annular seal member. The second back chamber is provided radially outwardly of the first back chamber and between the orbiting end plate and the thrust bearing, while the third back chamber is provided radially outwardly of the second back chamber. Oil passages are provided to introduce lubricating oil accommodated in the casing into the first chamber in which a discharge pressure acts. The oil passages act to supply part of the lubricating oil to the second chamber and then to the third chamber while reducing the pressure of the lubricating oil until the lubricating oil is eventually introduced into the suction chamber.
