Title:
MUTUAL ROTATION TYPE SCROLL COMPRESSOR HAVING POSITION-CHANGEABLE BEARING APPLIED THERETO
Document Type and Number:
WIPO Patent Application WO/2018/056634
Kind Code:
A1
Abstract:
The present invention relates to a mutual rotation type scroll compressor in which the position of a bearing supporting scrolls is changed by a torque repulsive force applied to the bearing by the compression-repulsion of a compressed fluid and the change of the bearing position is converted into a sealing force with respect to a compression pocket regulated by a wrap of mutual rotation type scrolls, thereby increasing the sealing force of the compression pocket. A bearing housing is rotatably installed in a housing receiving groove and a rotational center (C2) of a second scroll is located at a position eccentric with respect to a rotational center (G) of the bearing housing. Therefore, as the bearing housing (16) is rotated by a torque repulsive force (Fθ) applied to a second scroll, a part of the torque repulsive force (Fθ) is converted into a sealing force (Fseal) resisting a sealing interference force (Fr), whereby a wrap of the second scroll comes into close contact with a wrap of a first scroll by the sealing force.
