Claims

[Scope of utility model registration request]

A fixed scroll and an orbiting scroll each having a spiral wrap erected on the inner surface of an end plate are meshed with each other at different angles to form a compression chamber, and in order to bypass the gas that is being compressed within this compression chamber. A capacity control block incorporating a bypass passage and a valve mechanism for opening and closing this bypass passage is fixedly installed in the housing together with the fixed scroll in close contact with the outer surface of the fixed scroll, and the outer peripheral surface of the capacity control block and the housing are fixedly installed together with the fixed scroll. A suction chamber and a discharge cavity are formed by partitioning the inside of the housing by a sealing member interposed between the housing and the inner peripheral surface of the housing, and the discharge cavity is communicated with a discharge chamber formed outside the housing. A scroll type compressor having a discharge gas passage formed in an outer circumferential wall of the housing, wherein the seal member is arranged to be inclined toward the fixed scroll on the side of the discharge gas passage. compressor.
