Abstract

L'invention concerne un compresseur (10), en particulier un compresseur destiné à comprimer un agent frigorifique, comportant un ou plusieurs pistons (12), et un bloc-cylindres (16), ainsi qu'un boîtier de compresseur logeant au moins partiellement un compresseur, le(les) piston(s) (12) étant disposé(s) dans des alésages de cylindre ou des cylindres (14) correspondant au moins partiellement dans le bloc-cylindres (16) et/ou dans le boîtier de compresseur de manière à se déplacer dans un mouvement de va-et-vient, le compresseur (10) comportant en outre un tube d'impédance (36) ainsi qu'une sortie (30) destinée à faire sortir l'agent frigorifique provenant du compresseur, (10) en particulier une bride de sortie (32). Le compresseur (10) comporte pour un ou plusieurs cylindres (14), en particulier pour deux cylindres (14), un volume sous haute pression (24) associé ainsi qu'un volume sous haute pression commun (26), dans lequel débouchent les volumes individuels sous haute pression (24). Selon l'invention, le volume commun sous haute pression (26) est en liaison avec la sortie (30) et le tube d'impédance (36) est disposé dans la liaison entre le volume commun sous haute pression (26) et la sortie (30) ou forme la liaison entre le volume commun sous haute pression (26) et la sortie (30). L'invention concerne également une installation frigorifique et une climatisation correspondante.
