Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2005/038254
Kind Code:
A2
Abstract:
A scroll compressor, wherein an approximately annular seal part in slidable contact with the end plate of a rotary scroll while spreading from the outermost peripheral inner wall surface of a lap to the outside to have the external wall surface of a fixed scroll roughly along the inner wall surface, an approximately annular recessed part positioned on the outside of the approximately annular seal part, and a recessed part communicating with the suction port of the fixed scroll in the independent form of the approximately annular recessed part are formed in the opposed surface of the fixed scroll to the end plate of the rotary scroll positioned around the outside of the lap. Thus, since a back pressure on the rotary scroll is increased, the overturning phenomenon of the rotary scroll can be suppressed.
