Capacity Varying Device for a Scroll Compressor

摘要

A capacity varying device for a scroll compressor including a fixed scroll and an orbiting scroll both located in a casing, a low pressure passage formed by an orbiting motion of the orbiting scroll that communicates with a suction side, an intermediate pressure passage formed by the orbiting motion of the orbiting scroll that communicates with an intermediate pressure side, a rotating device rotatably coupled to the fired scroll and having a connection passage therein, and an operating device mounted at the fixed scroll and configured to rotate the rotating device such that the low pressure passage and the intermediate pressure passage are connected/disconnected to/from each other via the connection passage of the rotating device.
