Amendment July 26, 1986 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] A fixed scroll member having a spiral body provided on one surface of a plate and a movable scroll member having a spiral body provided on one surface of the plate, the angles of both spiral bodies being shifted. The movable scroll members are overlapped in an interlocking state, and the movable scroll members are moved relative to the fixed scroll member so as to move on a circular orbit to form a closed space between both spiral bodies and take in fluid. In a scroll type compressor that moves the space toward the center with movement and performs a unidirectional continuous fluid compression action with a decrease in volume, a tip seal is provided on the tip surface of both spiral bodies. 1. A scroll type compressor, characterized in that a chip seal having a groove and a concave portion having an arcuate cross section is disposed in the chip seal groove.

Claims (1)

[Scope of utility model registration request] A fixed scroll member having a spiral body provided on one surface of a plate and a movable scroll member having a spiral body provided on one surface of the plate are overlapped in a mutually meshing state with the angles of both spiral bodies being shifted. , the movable scroll member is moved relative to the fixed scroll member so as to move on a circular orbit, and fluid is taken in while forming a closed space between both spiral bodies, and the space is centered as the movable scroll member moves. In a scroll type compressor which is configured to perform unidirectional continuous flow compression by moving in the same direction and reducing the volume, tip seal grooves are formed on the tip surfaces of both the spiral bodies, and a tip seal groove is formed in the tip surface of each of the spiral bodies. A scroll type compressor, characterized in that a chip seal having a recessed portion is disposed in the chip seal groove.
