Title: Scroll type compressor
Inventor: TSUMAGARI YUICHI
IPC: F04C18/02
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To mitigate thrust force acting on a turning scroll while abolishing a pressure regulating valve. SOLUTION: A back pressure chamber 117 for introducing a high pressure refrigerant delivered from a delivery hole 112c is formed in a bearing box 112d for rotatably connecting a turning scroll 112 to a crank part 115a, and the back pressure chamber 117 and a suction chamber 113 side (the suction side) are airtightly partitioned by a first seal member 118a. Thus, since delivery pressure acting from the back face side of the turning scroll 112 becomes only a part corresponding to the back pressure chamber 117, back thrust force by pressure of the back pressure chamber 117 can be prevented from becoming larger than compressive thrust force by compressive reaction so that the compressive thrust force can be mitigated while abolishing the pressure regulating valve.
