Title:
SCROLL-TYPE COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2003/102421
Kind Code:
A1
Abstract:
An adjustment mechanism (56) for generating overturn- prevention moment is provided in a scroll-type compressor (1). In a revolution angle region where overturning moment acting on a movable scroll (26) during its revolution is equal to or more than a predetermined value, the mechanism reduces the overturning moment. Because of the mechanism, pressing force of the movable scroll (26) to a fixed scroll (22) is caused to correspond to the variation of overturning moment induced by the revolution of the movable scroll (26), so that the revolution movement of the movable scroll (26) is stabilized and compression efficiency of the scroll-type compressor (1) is enhanced.
