Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
Abstract:
(EN) A scroll compressor includes a fixed scroll including a fixed mirror-like surface and a fixed wrap that is extended from the fixed mirror-like surface, formed in a hybrid curve, and includes a thick portion thicker than other portions; an orbiting scroll including an orbiting mirror-like surface and an orbiting wrap extended from the orbiting mirror-like surface and formed in a hybrid curve; and a rotating shaft configured to rotate the orbiting scroll, wherein the orbiting scroll revolves relative to the fixed scroll. A center of a curve of a center portion of the fixed wrap is located at a position offset by a predetermined distance in a direction of reducing a thickness of the thick portion of the fixed wrap from a center of the fixed mirror-like surface, and a center of a curve of a center portion of the orbiting wrap is offset to correspond to the fixed wrap.
(FR) L'invention concerne un compresseur à spirale comprenant une spirale fixe comprenant une surface de type miroir fixe et une enveloppe fixe qui est étendue à partir de la surface de type miroir fixe, formée dans une courbe hybride et comprenant une partie épaisse plus épaisse que d'autres parties ; une spirale orbitale comprenant une surface de type miroir orbital et une enveloppe orbitale s'étendant à partir de la surface de type miroir orbital et formée dans une courbe hybride ; et un arbre rotatif conçu pour faire tourner la spirale orbitale, la spirale orbitale tournant par rapport à la spirale fixe. Un centre d'une courbe d'une partie centrale de l'enveloppe fixe est situé à une position décalée selon une distance prédéfinie dans une direction de réduction d'une épaisseur de la partie épaisse de l'enveloppe fixe à partir d'un centre de la surface de type miroir fixe, et un centre d'une courbe d'une partie centrale de l'enveloppe orbitale est décalé pour correspondre à l'enveloppe fixe.
