Claims

[Scope of utility model registration request]

A compression chamber is formed by interlocking a fixed scroll and an orbiting scroll each having a spiral wrap erected on the inner surface of an end plate at different angles from each other, and this orbiting scroll is prevented from rotating by a rotation prevention mechanism. The gas sucked into the compression chamber from the suction chamber formed in the housing is compressed and discharged into the discharge cavity formed in the housing by rotating the gas by the rotation drive mechanism. A discharge gas passage that communicates the cavity with a discharge chamber formed outside the housing is bored in the outer peripheral wall of the housing, and a bypass port that bypasses the gas that is being compressed in the compression chamber is provided on the end plate of the fixed scroll. A capacity control block, which includes a bypass passage that communicates this bypass port with the suction chamber and a piston valve that opens and closes this bypass passage, is installed in close contact with the outer surface of the end plate of the fixed scroll. In the scroll compressor fixedly installed in the housing, the cylinder in which the piston valve is slidably fitted is provided so that its axis is inclined toward the fixed scroll on the side of the discharge gas passage. A scroll compressor characterized by:
