Abstract

La présente invention concerne un compresseur alternatif comprenant : un boîtier ; des blocs-cylindres avant et arrière dans lesquels une pluralité d'alésages de cylindre est formée et qui sont accouplés au boîtier ; des pistons logés dans les alésages de cylindre respectifs de sorte que les pistons puissent être déplacés selon un mouvement de va-et-vient ; des orifices d'aspiration formés sur au moins un côté des blocs-cylindres avant et arrière ; des silencieux d'aspiration reliés aux orifices d'aspiration et formés sur au moins un côté des blocs-cylindres avant et arrière ; et des premiers passages d'aspiration permettant l'interconnexion des silencieux d'aspiration et de chambres à plateau cyclique formées dans les blocs-cylindres avant et arrière. Ainsi, la pulsation provoquée par l'aspiration et l'évacuation d'un réfrigérant peut être supprimée dans toute la mesure du possible au moyen des silencieux d'aspiration et des silencieux d'évacuation disposés au niveau des blocs-cylindres avant et arrière, ainsi que des premiers et seconds passages d'aspiration, ce qui permet de réduire le bruit et les vibrations.
