Title (EN) SCROLL TYPE COMPRESSOR
(FR) COMPRESSEUR À SPIRALES
(JA) スクロール型圧縮機
Abstract:
(EN) Provided is a scroll type compressor that suppresses fluctuation in the load applied to press an orbiting scroll against a fixed scroll, mechanical shock when the compressor is activated, and noise, while also exhibiting excellent durability. A surrounding elastic body (51) and a bottom elastic body (52) compressed in the axial direction of a main shaft (31) are placed between a stopper pin (41) provided on the orbiting scroll side and a concave section (42) created on the main shaft (31) side. Machining errors in the various sections are absorbed to allow the orbiting scroll to stay in contact with the fixed scroll at all times, and compression chamber sealing is maintained.
(FR) L'invention a trait à un compresseur à spirales qui élimine la fluctuation de la charge appliquée pour appuyer une spirale tournante sur une spirale fixe, le choc mécanique qui se produit lorsque le compresseur est mis en marche, ainsi que le bruit, et qui présente également une excellente durabilité. Un corps élastique englobant (51) et un corps élastique inférieur (52) compressés dans la direction axiale d'un arbre principal (31) sont placés entre une goupille d'arrêt (41) installée sur le côté de la spirale tournante et une section concave (42) créée sur le côté de l'arbre principal (31). Les erreurs d'usinage des différentes sections sont absorbées afin que la spirale tournante reste en contact permanent avec la spirale fixe, et l'étanchéité de la chambre de compression est maintenue.
(JA)  旋回スクロールの固定スクロールへの押し付け荷重のバラつきを抑え、圧縮機の起動時における衝撃を抑え、騒音を抑えるとともに、耐久性を優れたものとすることのできるスクロール型圧縮機を提供することを目的とする。  旋回スクロール側のストッパピン41と、主軸31側の凹部42との間に、周囲弾性体51と、主軸31の軸線方向に圧縮状態とされた底部弾性体52と、を介在させることで、旋回スクロールを、各部の加工誤差を吸収して常時固定スクロールに接触させて圧縮室のシール性を維持する。
