Title
(EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
(JA) スクロール圧縮機
Abstract
(EN)
A scroll compressor wherein an eccentric rolling bearing and a main rolling bearing have enhanced reliability achieved by controlling both the amount of supply of oil from a high-pressure region to a back pressure chamber and the amount of supply of oil from the high-pressure region to the eccentric rolling bearing and to the main rolling bearing. A scroll compressor provided with a back pressure chamber oil supply route (25) for supplying a lubricating oil (7) from a high-pressure region (21) to a back pressure chamber (22), and also with a compression chamber oil supply route (26) for supplying the lubricating oil (7) from the back pressure chamber (22) to a compression chamber (23), wherein one opening (25c) of the back pressure chamber oil supply route (25) passes through the seal member (24) in a reciprocating manner.

La présente invention concerne un compresseur à spirale dans lequel un palier à roulement excentrique et un palier à roulement principal ont amélioré la fiabilité obtenue par le contrôle de la quantité d'alimentation d'huile depuis une zone de haute pression vers une chambre de contre-pression ainsi que la quantité d'alimentation d'huile depuis la zone de haute pression vers le palier à roulement excentrique et vers le palier à roulement principal. L'invention concerne un compresseur à spirale équipée d'un chemin d'alimentation d'huile de chambre de contre-pression (25) pour alimenter une huile lubrifiante (7) depuis une zone de haute pression (21) vers une chambre de contre-pression (22), et également d'un chemin d'alimentation d'huile de chambre de compression (26) pour alimenter l'huile lubrifiante (7) depuis la chambre de contre-pression (22) vers une chambre de compression (23), une ouverture (25c) du chemin d'alimentation d'huile de chambre de contre-pression (25) traversant l'organe d'étanchéité (24) dans un mouvement de va-et-vient.
