Title:
Scroll fluid machine and tip seal
Document Type and Number:
Japanese Patent JP6325041
Kind Code:
B2
Abstract:
The present invention improves performance of a scroll fluid machine by effectively exhibiting a function of a tip seal installed at a tooth tip of a wall body even when a continuous slope is provided to the wall body. A slope in which the distance between opposing surfaces of opposing end plates continuously reduces from the outer peripheral surface toward the inner peripheral surface is provided, and a tip seal (7) that comes into contact with an opposing tooth bottom so as to seal a fluid is provided to a tip seal groove (3d) formed at a tooth tip of a wall body (3b) corresponding to the slope. A groove bottom (3d1) of the tip seal groove (3d) is formed into a shape in which the center portion (3d2) in the groove width direction is deepest. The tip seal (7) is formed such that the center portion (7a1), in the width direction, of the bottom (7a) of the tip seal (7) facing the groove bottom (3d1) projects farther than both side portions (7a2).
