Abstract
(EN)
A compressor (1) is provided with: a bearing part (30) which rotatably supports a rotation shaft (20); a casing (10) which houses the rotation shaft (20), a drive part (50), and a compressor body (60) and in which a lubricant for lubricating the bearing part (30) is stored; and a plurality of suction pipes (80) which each supply, into the casing (10), a fluid that has not yet been compressed. The plurality of suction pipes (80) include: a first suction pipe (81) connected to the casing (10); and a second suction pipe (82) connected to the casing (10), at a position where relatively easy contact with the lubricant is enabled as compared to a position where the first suction pipe (81) is connected to the casing (10).
(FR)
L'invention concerne un compresseur (1) comprenant : une partie palier (30) qui supporte de manière rotative un arbre de rotation (20) ; un boîtier (10) qui loge l'arbre de rotation (20), une partie d'entraînement (50) et un corps de compresseur (60) et dans lequel est stocké un lubrifiant pour lubrifier la partie palier (30) ; et une pluralité de tuyaux d'aspiration (80) qui alimentent chacun, dans le boîtier (10), un fluide qui n'a pas encore été comprimé. La pluralité de tuyaux d'aspiration (80) comprend : un premier tuyau d'aspiration (81) relié au boîtier (10) ; et un second tuyau d'aspiration (82) relié au boîtier (10), à une position où un contact relativement facile avec le lubrifiant est permis par comparaison à une position dans laquelle le premier tuyau d'aspiration (81) est relié au boîtier (10).
