摘要： Base wraps 21a and 31a of a fixed scroll 20 and orbiting scroll 30 both have spiral lengths that satisfy specified compression ratio in low speed drive region. Spiral shaped extension wraps 21b and 31b are provided for at least one of the base wraps 21a and 31a, extended from the spiral end position thereof, and a displacement is effected in the direction in which the thickness of the wraps 21 and 31 becomes thinner, at least at either the inner walls of the extension wraps 21b and 31b or at the outer walls of the wraps 21 and 31 in opposition thereto, making the interrelationship greater.

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： In a scroll compressor, an outer wall curve of a scroll lap of a fixed scroll and an inner wall curve of a scroll lap of an orbiting scroll are formed of involute curves whose basic circle radius is defined as “a”, an inner wall curve of the scroll lap of the fixed scroll and an outer wall curve of the scroll lap of the orbiting scroll are formed of involute curves whose basic circle radius is defined as “b”, and a value of a/b which is a ratio of the basic circle radius a and the basic circle radius b is set to a value exceeding 1.0 and less than 1.5. With this structure, a compression chamber formed on the side of the inner wall of the scroll lap of the orbiting scroll is compressed faster than a compression chamber formed on the side of the outer wall of the scroll lap of the orbiting scroll, and leakage loss during compression process can be reduced.
