ABSTRACT:
A multiple-turn scroll compressor has a first scroll member and a second scroll member. Each of the scroll members has a scroll blade which is engaged with the other. A shaft has an eccentric portion which supports the first scroll member. A cylindrical guide is provided rotatably on a housing and has a guide groove at one end. A slider fixed on the first scroll member engages with the guide groove and slides on it. Driving forces are transmitted from the shaft to the first scroll member through the eccentric portion. The first scroll member is prevented from rotating on its own axis by the engagement of the cylindrical guide and slider but not from orbiting.
