Abstract

PURPOSE:To make it possible to inhibit a movable scrol member from rotating and to reduce the number of required component pats to aim at mass-producing scrol type compressors, by engaging projections on a stationary ring fixed to a front side housing, with recesses in a movable ring attached to the movable scrol member. CONSTITUTION:When a rotary shaft 4 is rotated through a clutch 3, an eccentric shaft 7 is also rotated integrally with the shaft 4 so that a movable scrol member 8 is subjected to turning motion. In this arrangement, the member 8 is fitted on the eccentric shaft 7 by means of a radial needle bearing 10 so that it tends to rotate. However, since projections 23... on a stationary ring 21 fixed to a front side housing 1 are engaged in recesses 25... in a movable ring 24 attached to the movable scrol member 8, the movable scrol member 8 is inhibited from rotating while it is allowed to revolve so that it is possible to smoothly promote the value reducing operation of a compression chamber V, and as well with the constitution excellent in mass-productivity it is possible to inhibit the member 8 from rotating.

ロックを使用するので部品点数が多い欠点がある。This kind of scroll type pressure IIi! The problem with this system is to drive the movable scroll member so that it revolves on a constant circular trajectory without rotating on its own axis. In the above publication, in order to prevent the movable scroll member from rotating, mutually intersecting guide grooves are formed on the facing surfaces of the movable scroll member and the fixing ring on the housing side, and frame-shaped anti-rotation blocks are formed in these guide grooves. A technique has been proposed that allows sliding contact. However, the above-described method has the disadvantage that molding the guide groove is troublesome and requires a large number of parts because a frame-shaped rotation prevention block is used.
