A compressor apparatus has a housing (22) having first (53) and second (58) ports along a flowpath. One or more working elements (26, 28) cooperate with the housing to define a compression path between suction and discharge locations along the flowpath. A check valve (70) has a valve element having a first condition permitting downstream flow along the flowpath and a second condition blocking a reverse flow. Sound suppressing means (120, 220, 320) at least partially surround the flowpath upstream of the valve element (70).
L'invention concerne un compresseur, qui comprend un boîtier (22) présentant un premier (53) et un second (58) orifices le long d'un circuit d'écoulement. Un ou plusieurs éléments de travail (26, 28) coopèrent avec le boîtier pour délimiter un circuit de compression entre des emplacements d'aspiration et d'évacuation, le long du circuit d'écoulement. Un clapet anti-retour (70) comprend un élément de clapet qui présente un premier état permettant un écoulement vers l'aval le long du circuit d'écoulement, et un second état de blocage d'une inversion de débit. Des moyens d'atténuation du bruit (120, 220, 320) entourent au moins partiellement le circuit d'écoulement en amont de l'élément de clapet (70).
