Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
(JA) スクロール型圧縮機
Abstract:
(EN) This scroll compressor is provided with a scroll member which has a compression chamber which compresses a work fluid, a housing which houses the scroll member, a second drive-side shaft (72c) which discharges compressed work fluid from the compression chamber and rotates about an axis with respect to a second drive-side housing unit (3b1) of the housing, and a seal member (16) which is fixed to the outer periphery of the second drive-side shaft (72c) and contacts and forms a seal with the inner peripheral surface of the second drive-side housing unit (3b1). On the inner peripheral surface that contacts the seal member (16), the second drive-side housing unit (3b1) has a wear-resistant part.
(FR) Le compresseur à spirale de l’invention est équipé : d’un élément spirale qui possède une chambre de compression dans laquelle un fluide de travail est comprimé ; d’un logement qui admet l’élément spirale ; d’une seconde partie axe côté entraînement (72c) qui tout en déchargeant de la chambre de compression le fluide de travail comprimé, exerce une rotation autour d’une ligne axiale vis-à-vis d’une seconde partie admission côté entraînement (3b1) du logement ; et d’un élément de scellement (16) fixé à la périphérie externe de la seconde partie axe côté entraînement (72c), et scellant par contact une face périphérique interne de la seconde partie admission côté entraînement (3b1). La seconde partie admission côté entraînement (3b1) est à son tour équipée d’une partie antifriction sur une face périphérique interne en contact avec l’élément de scellement (16).
(JA) 作動流体を圧縮する圧縮室を有するスクロール部材と、スクロール部材を収容するハウジングと、圧縮された作動流体を圧縮室から吐出するとともにハウジングの第2駆動側収容部(3b1)に対して軸線回りに回転する第2駆動側軸部(72c)と、第2駆動側軸部(72c)の外周に固定され、第2駆動側収容部(3b1)の内周面に対して接触してシールするシール部材(16)とを備えている。第2駆動側収容部(3b1)は、シール部材(16)に接触する内周面に、耐摩耗部を備えている。
