Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2019/138553
Kind Code:
A1
Abstract:
In a scroll compressor (1) according to the present invention, a compression chamber (RC) is formed between a fixed scroll (40) and an orbiting scroll (30) due to meshing of an orbiting lap (32) and a fixed lap (42). The scroll compressor (1) is provided with a capacity control valve (62) for opening or closing a bypass path (71) providing communication between the compression chamber (RC) and a suction opening (44) serving as a refrigerant supply portion for supplying an external gas refrigerant to the compression chamber (RC). The capacity control valve (62) is provided with a valve body (62a) which has a valve body hole (62ac) providing communication between a rear end-side opening portion (62e) opening on a rear-end surface and a front end-side opening portion (62f) opening on a front end-side lateral surface. The valve body (62a), when positioned in a valve-closed position, has the front end-side opening portion (62f) closed to block the bypass path (71), and, when positioned in a valve-open position, has the front end-side opening portion (62f) opened to open the bypass path (71).
