Abstract
PURPOSE: To increase volume which is contributive to compression by providing a projection on the face where spiral of a moving scroll member faces outwards.
CONSTITUTION: A portion from spot B1 to spot B2 on the face where spiral 242 of a moving scroll member 24 faces outwards is formed to creep on a circular arc of radius R1 (R1=R0-r), and the wall is left thick only at a projection 244. For circular motion of the moving scroll member along the track of radius r, one spot of the portion on outward face of the spiral 242 which is formed along the circular arc of radius R1 comes always in contact with the inside of a cylinder side wall 13, and the contact point continuously moves from spot B2 to spot B1, therefore the outward face between the spots B1 and B2 is also contributive to compression of a fluid. Volume of the compression space can be increased consequently.
