Abstract

L'invention concerne un compresseur alternatif (100) pour un dispositif de refroidissement (200) doté d'un circuit fermé (C) ayant une dérivation principale (M), dans laquelle un premier débit (X) de réfrigérant en circulation entre dans ledit compresseur et au moins une première dérivation d'économiseur ou dérivation secondaire (E), dans laquelle un second débit (XI) de réfrigérant circule à une pression différente de la pression dudit premier débit (X) de réfrigérant, ledit compresseur étant doté d'au moins un cylindre (110) et d'au moins un piston (111) effectuant un mouvement alternatif dans ledit au moins un cylindre, entre un point mort haut (S) et un point mort bas (I) et comprenant au moins un conduit d'aspiration pour l'entrée dudit premier débit de réfrigérant, ainsi qu'au moins un orifice (107) ménagé dans la paroi dudit cylindre pour l'entrée dudit second débit de réfrigérant, de telle manière que ledit piston expose au moins en partie ledit au moins un premier orifice d'entrée (107), au moins pendant sa course d'entrée et recouvre ledit au moins un orifice au moins pendant sa course de compression, caractérisé en ce que ledit au moins un premier orifice d'entrée (107) a une forme de fente dont la dimension principale est sensiblement transversale à l'axe (A) dudit cylindre.
