Title (EN) MUTUAL ROTATION TYPE SCROLL COMPRESSOR HAVING POSITION-CHANGEABLE BEARING APPLIED THERETO
(FR) COMPRESSEUR À SPIRALES DE TYPE À ROTATION MUTUELLE COMPORTANT UN PALIER À CHANGEMENT DE POSITION APPLIQUÉ À CELUI-CI
(KO) 위치 가변 베어링이 적용된 상호 회전형 스크롤 압축기
Abstract: front page image
(EN) 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.
(FR) La présente invention concerne un compresseur à spirale de type à rotation mutuelle dans lequel la position d'un palier de supportant des spirales est modifiée par une force de répulsion de couple appliquée au palier par la compression-répulsion d'un fluide comprimé et le changement de la position de palier est converti en une force d'étanchéité par rapport à une poche de compression régulée par une enveloppe de spirales de type à rotation mutuelle, ce qui permet d'augmenter la force d'étanchéité de la poche de compression. Un corps de palier est installé en rotation dans une rainure de réception de corps et un centre de rotation (C2) d'une deuxième spirale se situe dans une position excentrique par rapport à un centre de rotation (G) du corps de palier. Par conséquent, lorsque le corps de palier (16) est entraîné en rotation par une force de répulsion de couple (Fθ) appliquée à une deuxième spirale, une partie de la force de répulsion de couple (Fθ) est convertie en une force d'étanchéité (Fseal) résistant à une force d'interférence d'étanchéité (Fr), moyennant quoi une enveloppe de la deuxième spirale entre en contact étroit avec une enveloppe d'une première spirale par la force d'étanchéité.
(KO) 본 발명은 스크롤을 지지하는 베어링의 위치가, 압축 유체의 압축 반발에 의해 상기 베어링에 작용하는 토크 반발력에 의해 변위하면서 상호 회전형 스크롤의 랩에 의해 규정되는 압축 포켓에 대한 밀봉력으로 변환됨으로써, 압축 포켓의 밀봉력을 높인 상호 회전형 스크롤 압축기에 관한 것으로, 베어링 하우징이 상기 하우징 수용홀에 회전 가능하게 설치되고, 상기 베어링 하우징의 회전 중심(G)에 대해 편심된 위치에 제2스크롤의 회전중심(C2)이 위치하여서, 제2스크롤에 작용하는 토크반발력(Fθ)에 의해 상기 베어링 하우징(16)이 회전함에 따라, 상기 토크반발력(Fθ)의 일부가 밀봉방해력(Fr)에 대항하는 밀봉력(Fseal)으로 전환됨으로써, 상기 밀봉력에 의해 상기 제2스크롤의 랩이 제1스크롤의 랩에 밀착되도록 한 것을 특징으로 한다.
