Title:
SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JPH0240092
Kind Code:
A
Abstract:

PURPOSE: To prevent leakage between scroll members by supplying axial force on a back surface of an orbiting scroll member toward a cooperating fixed scroll member.

CONSTITUTION: When a compressor is actuated, the axial response of an orbiting scroll member 50 toward a cooperating fixed scroll member 48 is effected when the compressor compresses refrigerant fluid and release it to a housing chamber 110. When the housing chamber 110 is pressurized, the released pressure occupies the volume in the radial inner side as seen from an inner wall 166. A seal element 158 is expanded toward the radial outer side. The scroll member 50 is moved to the axial upper side away from a thrust surface 55.
