Abstract

Le compresseur à spirales (1) comporte une enveloppe de compresseur (2) ayant une sortie de refoulement (4) ; une volute fixe (7) comprenant une plaque de base fixe (11) et un passage de refoulement (16) formé dans la plaque de base fixe (11) et doté d’un orifice de refoulement (17) débouchant dans un volume de pression de refoulement (18) défini par l’enveloppe de compresseur (2) et la volute fixe (7) ; et un déflecteur (29) agencé dans le volume de pression de refoulement (18), recouvrant l’orifice de refoulement (17) et délimitant une ouverture de refoulement (31) située en regard de la sortie de refoulement (4), le déflecteur (29) étant configuré pour forcer un flux de gaz frigorigène comprimé sortant de l’orifice de refoulement (17) à passer d’une direction axiale à une direction radiale et étant configuré pour diriger ledit flux de gaz frigorigène comprimé vers la sortie de refoulement (4). Figure 2The scroll compressor (1) is provided with a compressor casing (2) having a discharge outlet (4); a fixed volute (7) comprising a fixed base plate (11) and a discharge passage (16) formed in the fixed base plate (11) and provided with a discharge orifice (17) opening into a pressure volume discharge (18) defined by the compressor casing (2) and the fixed volute (7); and a deflector (29) arranged in the discharge pressure volume (18), covering the discharge orifice (17) and delimiting a discharge opening (31) located opposite the discharge outlet (4), the deflector (29) being configured to force a flow of compressed refrigerant gas exiting the discharge port (17) from an axial direction to a radial direction and being configured to direct said flow of compressed refrigerant gas towards the discharge outlet (4).
