Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR A HELICE
Abstract:
(EN) A scroll compressor in which a discharge muffler (24) is disposed on the stationary spiral blade frame (7) in such a way that a first discharge space (24a) is formed and first and second discharge passages (25), (26) to pierce through the stationary blade (7) and bearing member (29) for allowing the first discharge space (24a) to communicate with the inside of a closed vessel (1) are provided so that an opening part (52) of the second communicating hole toward the inside of the closed vessel (1) may be positioned higher than the level of lubricant oil in the lubricant oil reservoir (31) by means of guide parts (29). Because of the position of the opening part (52) of the second communicating hole directed toward the inside of the closed vessel (1), which position is kept by the guide parts (29) higher than the lubricant oil level in the lubrican oil reservoir (31), the discharge passage can easily be formed without using additional members.
(FR) Compresseur à hélice dans lequel un échappement de refoulement (24) est disposé sur le bâti de la pale hélicoïdale fixe (7) de telle manière qu'un premier espace de refoulement (24a) est formé, et des premier et deuxième passages de refoulement (25, 26), traversant la pale fixe (7) et le palier (29) pour mettre en communication le premier espace de refoulement (24a) avec l'intérieur d'un récipient fermé (1), sont prévus de sorte qu'une partie d'ouverture (52) du deuxième orifice de communication dirigée vers l'intérieur du récipient fermé (1) puisse être positionnée, au moyen de parties de guidage (29), plus haut que le niveau d'huile lubrifiante contenue dans le réservoir (31) prévu à cet effet. Du fait de la position de la partie d'ouverture (52) du deuxième orifice de communication dirigée vers l'intérieur du récipient fermé (1), laquelle position est maintenue par les parties de guidage (29) plus haut que le niveau d'huile lubrifiante contenue dans le réservoir (31), le passage de refoulement peut aisément être formé sans recourir à des éléments additionnels.
