Title
(EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALES
Abstract
(EN)
Disclosed herein is a scroll compressor capable of optimizing a position where a load is applied from a support member to an orbiting scroll. The scroll compressor includes a fixed scroll fixed to an inside of a body, an orbiting scroll configured to orbit in engagement with the fixed scroll, a rotary shaft configured to allow the orbiting scroll to orbit, a holding member configured to hold the fixed scroll from a side opposite to the orbiting scroll, and a support member arranged between the rotary shaft and the holding member to support the orbiting scroll by a load applied to a position away from a center of the orbiting scroll.
(FR)
L'invention concerne un compresseur à spirales pouvant optimiser une position d'application d'une charge à partir d'un élément de support vers une spirale orbitale. Le compresseur à spirales comprend une spirale fixe fixée à l'intérieur d'un corps, une spirale orbitale conçue pour orbiter en prise avec la spirale fixe, un arbre rotatif conçu pour permettre à la spirale orbitale d'orbiter, un élément de retenue conçu pour retenir la spirale fixe à partir d'un côté opposé à la spirale orbitale, et un élément de support agencé entre l'arbre rotatif et l'élément de retenue afin de porter la spirale orbitale au moyen d'une charge appliquée à une position éloignée d'un centre de la spirale orbitale.
