Abstract
(EN) [Problem] To provide a scroll compressor with improved workability when communicating a back pressure chamber and a compression chamber. [Solution] The present invention comprises: a back pressure chamber 39 that is formed in a back surface of a mirror plate 31 of a movable scroll 22 of a scroll compressor 1; and a communication hole 51 that is formed in the mirror plate 31 of the movable scroll 22, and communicates the back pressure chamber 39 and a compression chamber 34. The communication hole 51 is structured from a large-diameter hole section 52 that is located in the back pressure chamber 39 side of the mirror plate 31 of the movable scroll 22, and a small-diameter hole section 53 that continues from the large-diameter hole section 52 to reach the compression chamber 34.
(FR) Le problème décrit par la présente invention est de fournir un compresseur à spirale présentant une aptitude au façonnage améliorée lors de la mise en communication d'une chambre de contre-pression et d'une chambre de compression. À cet effet, la présente invention comprend : une chambre de contre-pression (39) qui est ménagée dans une surface arrière d'une plaque de miroir (31) d'une spirale mobile (22) d'un compresseur à spirale (1) ; et un trou de communication (51) qui est ménagé dans la plaque de miroir (31) de la spirale mobile (22), et met en communication la chambre de contre-pression (39) et une chambre de compression (34). Le trou de communication (51) est structuré à partir d'une section de trou de grand diamètre (52) qui est située dans la chambre de contre-pression (39) du côté de la plaque de miroir (31) de la spirale mobile (22), et d'une section de trou de petit diamètre (53) qui continue à partir de la section de trou de grand diamètre (52) afin d'atteindre la chambre de compression (34).
