Title (EN) COMPRESSOR
(FR) COMPRESSEUR
(JA) 圧縮機
Abstract:
(EN) This compressor comprises: a casing (1) that accommodates a rotating shaft (12), an electric motor (11), and a compressor main body (10), the casing (1) having an intake hole (31) that guides in a working fluid to a location corresponding to an axis (O1)-directional end surface of a stator core (24), and a discharge hole that discharges working fluid compressed by the compressor main body (10); and a pressing part that is provided only in the vicinity of a given circumferential position of the intake hole (31) in the outer peripheral edge of the axis (O1)-directional end surface of the stator core (24), the pressing part minimizing upturning of the end surface due to the working fluid taken in through the intake hole (31).
(FR) L'invention concerne un compresseur comprenant : un boîtier (1) contenant un arbre rotatif (12), un moteur électrique (11) et un corps principal de compresseur (10), le boîtier (1) présentant un trou d'admission (31) qui guide un fluide de travail vers un emplacement correspondant à la surface d'extrémité directionnelle d'axe (O1) d'un noyau statorique (24), et un trou de décharge qui évacue le fluide de travail comprimé par le corps principal de compresseur (10) ; et un élément de pression qui est disposé uniquement à proximité d'une position circonférentielle donnée du trou d'admission (31) dans le bord périphérique extérieur de la surface d'extrémité directionnelle d'axe (O1) du noyau statorique (24), l'élément de pression réduisant au minimum le retournement de la surface d'extrémité en raison du fluide de travail aspiré à travers le trou d'admission (31).
(JA) 回転軸(12)、電動機(11)及び圧縮機本体(10)を収容するとともに、ステータコア(24)の軸線(O1)方向の端面に対応する箇所に作動流体を導入する吸入孔(31)、及び、圧縮機本体(10)が圧縮した作動流体を吐出する吐出孔を有するケーシング(1)と、ステータコア(24)の軸線(O1)方向の端面の外周縁部における吸入孔(31)のある周方向位置の付近のみに設けられて、吸入孔(31)から吸入される作動流体による端面のめくり上がりを抑制する押さえ部と、を備える。
