Claims

[Scope of utility model registration request]

(1) A fixed scroll and a movable scroll each having a spiral wall erected on one surface of the substrate are combined at their walls with their center lines eccentrically arranged to form a compression chamber, and the scroll is movable. In a scroll compressor that compresses gas by revolving around the center line of a fixed scroll without rotating, the wall of one of the scrolls faces the substrate of the other scroll in close proximity. A seal groove extending along the longitudinal direction of the tip surface is formed in the spiral tip surface, and a string-shaped tip seal is spirally arranged in the seal groove, and the seal groove and the tip seal are arranged in a spiral shape. Between,
The dimensions of the seal groove and the tip seal are such that when the compressor is at room temperature and stopped, a larger clearance is created in the center side of the spiral than in the outer peripheral side in the groove width direction and/or groove depth direction of the seal groove. A scroll compressor characterized by:

(2) The scope of the utility model registration claim, in which the tip seal has a cross-sectional dimension that does not change in the longitudinal direction, and the seal groove is formed so that the portion on the center side of the spiral is wider and/or deeper than the portion on the outer peripheral side. Scroll compressor according to item 1.

(3) The scope of the utility model registration claim, wherein the seal groove has a cross-sectional dimension that does not change in the longitudinal direction, while the tip seal has a spiral center portion narrower and/or thinner than an outer peripheral portion. Scroll compressor according to item 1.
