Title (EN) COMPRESSOR SHOE
(FR) PATIN DE COMPRESSEUR
(JA) コンプレッサ用シュー
Abstract:
(EN) Provided is a compressor shoe capable of improving seizure resistance. The compressor shoe is provided with: a first sliding surface (51) in sliding contact with a piston (4); a second sliding surface (52) in sliding contact with a inclined plate (3); and a recess part (53) formed in the second sliding surface (52), wherein, when a vertically cut cross-section is shown such that the magnification in the height direction is 1000 and the magnification in the radial direction is 10, a connecting portion (55) between the second sliding surface (52) and the recess part (53) is formed in a round shape having a radius R2 greater than 5 mm.
(FR) L'invention concerne un patin de compresseur qui peut améliorer la résistance au grippage. Le patin de compresseur est pourvu : d'une première surface de glissement (51) en contact coulissant avec un piston (4) ; d'une seconde surface de glissement (52) en contact coulissant avec une plaque inclinée (3) ; et d'une partie évidement (53) formée dans la seconde surface de glissement (52) lorsqu'une section transversale découpée verticalement est représentée de telle sorte que le grossissement dans le sens de la hauteur soit de 1 000 et que le grossissement dans la direction radiale soit de 10, une partie de liaison (55) entre la seconde surface de glissement (52) et la partie évidement (53) se présentant sous une forme arrondie ayant un rayon (R2) supérieur à 5 mm.
(JA) 耐焼付性を向上させることが可能なコンプレッサ用シューを提供する。ピストン(4)と摺動する第一摺動面(51)と、斜板(3)と摺動する第二摺動面(52)と、前記第二摺動面(52)に形成される凹部(53)と、を具備し、高さ方向に切った断面を、前記高さ方向の倍率が1000倍かつ径方向の倍率が10倍になるように示した場合において、前記第二摺動面(52)と前記凹部(53)との接続部分(55)は、半径R2が5mmより大きいR形状に形成される。
