Title (EN) DISCHARGE VALVE ARRANGEMENT FOR A HERMETIC COMPRESSOR
(FR) ENSEMBLE SOUPAPE DE REFOULEMENT POUR COMPRESSEUR HERMÉTIQUE
Abstract: front page image
(EN)Discharge valve arrangement applied in a hermetic compressor used, for example, in household refrigeration systems comprising: a valve plate (10) closing an end of a compression cylinder (1) and provided with suction and discharge orifices (11, 12) contained within the inner contour of the axial projection (40) of the compression cylinder (1), said suction orifice (11) occupying an annular sector external to the axial projection of a discharge orifice (12) and being closed by a flexible suction vane (21) having a bending median portion (23). The valve plate (10) is provided with a plurality of discharge orifices (12) distributed in at least one of the regions defined externally and internally to the contour of the flexible suction vane (21), each discharge orifice (12) provided internally to the contour of the flexible suction vane (21) being axially aligned with a respective through opening (25) provided in said bending median portion (23).
(FR)L’invention concerne un ensemble soupape de refoulement installée dans un compresseur hermétique destiné, par exemple, à des systèmes de réfrigération domestiques, qui comprend: une plaque porte-soupape (10) fermant une extrémité d'un cylindre compresseur (1) et comportant des orifices d'aspiration et de décharge (11, 12) ménagés dans le contour interne de la projection axiale (40) du cylindre compresseur (1). L'orifice d'aspiration (11) occupe un secteur annulaire extérieur à la projection axiale de l'orifice de décharge (12) et est fermé par une aube d'aspiration souple (21) présentant une partie médiane cintrée (23). La plaque porte-soupape (10) est munie de plusieurs orifices de décharge (12) répartis dans au moins une des zones délimitées extérieurement et intérieurement par rapport au contour de l'aube d'aspiration souple (21), chaque orifice de décharge (12) disposé intérieurement par rapport au contour de l'aube d'aspiration souple (21) étant aligné axialement sur un trou débouchant (25) respectif ménagé dans ladite partie médiane cintrée (23).
