CA 2228779
A compressor having a two-piece piston formed from a separate piston head and piston stem. The piston head is made from a material having low porosity, such as steel, to minimize leakage of the compressing gas across the piston and the piston stem is manufactured from a lightweight material, such as aluminum, to minimize the force required to move the piston within the cylinder and thereby improve the efficiency of the compressor. A suction valve assembly is mounted on the piston head and the piston head, stem, and suction valve assembly are then connected tothe yoke of the compressor.
Compresseur muni d'un piston en deux pièces consistant en une tête et en une tige de piston indépendantes. La tête de piston est constituée d'un matériau de faible porosité, tel que l'acier, pour minimiser les fuites de gaz de compression du piston, la tige du piston étant composée d'un matériau léger, comme l'aluminium, pour minimiser la force nécessaire au déplacement du piston à l'intérieur du cylindre et améliorer l'efficacité du compresseur. Un ensemble de soupape d'aspiration est installé sur la tête du piston. Celle-ci, la tige et la soupape d'aspiration sont rattachées à la chape du compresseur.
