| 摘要 | PURPOSE: To improve sealing performance at the top of laps and to thereby reduce frictional loss, by applying a member provided with high accuracy by grinding or polishing an independent flat plate easy to machine over the surface to be held in sliding contact with the top of laps. CONSTITUTION: Members 17, 18, obtained from independent flat plates easy to machine to have a surface held in sliding contact with the top of laps and punched out to have grooves shaped in the same form as the laps, are applied over the bottom surface of a turning scroll 2 and a fixed scroll 1. The surfaces of these members 17, 18 are kept in sliding contact with the top of laps 1b, 2b to constitute compression chambers. With such an arrangement, it is enabled to improve the sealing performance at the top of the laps and to thereby reduce the frictional loss caused by sliding contact of the top of the laps with the surfaces of the members 17, 18.
