Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2017/138131
Kind Code:
A1
Abstract:
This scroll compressor is provided with an orbiting scroll and a fixed scroll. A compression chamber is formed by a combination of a fixed scroll spiral of the fixed scroll and an orbiting scroll spiral of the orbiting scroll. A sub-discharge port of the fixed scroll allows one of a first compression chamber defined by an inward facing surface of the fixed scroll spiral and an outward facing surface of the orbiting scroll spiral, and a second compression chamber defined by an outward facing surface of the fixed scroll spiral and an inward facing surface of the orbiting scroll spiral, to communicate with a discharge side, the first and second compression chambers being within the compression chamber. An opening portion of the sub-discharge port on the compression chamber side thereof includes a pair of side portions which extend in the circumferential direction of the spiral shape and are formed from involute curves, and a pair of connecting portions which extend in the radial direction of the spiral shape and connect the pair of side portions. Said opening portion is formed in such a way that the length, in the circumferential direction of the spiral shape, of the pair of side portions is longer than the length, in the radial direction of the spiral shape, of the pair of connecting portions, and is formed so as not to allow the first compression chamber and the second compression chamber to communicate with one another at any phase during one complete rotation of the orbiting scroll.
