The invention describes a packing cup (22) for the cylinder (10) of a reciprocating compressor. The packing cup (22) is formed from a first outer disc (28) and from a second inner disc (30), concentric to the first outer disc (28) and inside which a seat is formed for at least one sealing element for the piston (18). At least a part of the packing cup (22) is manufactured from a high- strength metallic alloy, obtained through a melting process and subsequent plastic deformation. The material is final-ly subjected to special heat treatments to improve the overall mechanical properties of the packing cup (22).
Cette invention concerne une coupelle de garniture (22) pour le cylindre (10) dun compresseur à piston. La coupelle de garniture (22) est formée dun premier disque externe (28) et dun second disque interne (30), concentrique au premier disque externe (28) et à lintérieur duquel est formé un siège pour au moins un élément détanchéité du piston (18). Au moins une partie de la coupelle de garniture (22) est faite dun alliage métallique de haute résistance obtenu par procédé de fusion et par déformation plastique subséquente. Le matériau est enfin soumis à des traitements thermiques spéciaux pour améliorer les propriétés mécaniques générales de la coupelle de garniture (22).
