Abstract:
(EN) This hermetic scroll compressor comprises: a ring-shaped thrust plate (40) having a through hole (41) through which a lubricating oil flows; and a crankshaft (11) that is placed on the upper surface of the thrust plate (40) and that has a flow path (17) formed in the interior thereof through which the lubricating oil having passed through the through hole (41) of the thrust plate (40) flows. In a sliding region of the crankshaft (11) and the thrust plate (40), a recessed groove (42) to which the lubricating oil is supplied from the through hole (41) is formed in the crankshaft (11) and/or the thrust plate (40). The outer end part (42a), in the radial direction, of the groove (42) is located inward of the outermost peripheral part of the sliding region.
(FR) L'invention concerne un compresseur à spirales hermétique, lequel compresseur comprend : une plaque de poussée de forme annulaire (40) ayant un trou traversant (41) à travers lequel circule une huile de lubrification ; et un vilebrequin (11) qui est disposé sur la surface supérieure de la plaque de poussée (40) et à l'intérieur duquel se trouve une trajectoire d'écoulement (17), à travers laquelle circule l'huile de lubrification ayant traversé le trou traversant (40) de la plaque de poussée (41). Dans une zone de coulissement du vilebrequin (11) et de la plaque de poussée (40), une rainure creuse (42) à laquelle l'huile de lubrification est délivrée à partir du trou traversant (41) est formée dans le vilebrequin (11) et/ou la plaque de poussée (40). La partie d'extrémité externe (42a), dans la direction radiale, de la rainure (42) est disposée à l'intérieur de la partie périphérique située le plus à l'extérieur de la région de coulissement.
(JA) 密閉型スクロール圧縮機は、潤滑油が流通する貫通孔(41)を有する円環形状のスラストプレート(40)と、スラストプレート(40)の上面に載置され、内部にスラストプレート(40)の貫通孔(41)を通過した潤滑油が流通する流通路(17)が形成されたクランク軸(11)とを備え、クランク軸(11)とスラストプレート(40)の摺動領域において、クランク軸(11)及びスラストプレート(40)の少なくともいずれか一方には、貫通孔(41)から潤滑油が供給される凹状の溝部(42)が形成され、溝部(42)の半径方向の外側端部(42a)は、摺動領域における最外周部よりも内側に位置している。
