Title
(EN) ROD FOR LINEAR COMPRESSOR
(FR) TIGE POUR COMPRESSEUR LINÉAIRE
Abstract
(EN)
The present invention relates to a rod (connecting rod) for interconnecting the piston to the end of the resilient member of linear compressors preferably operating at high frequency, comprised of an elongated rod (3) having at least two regions (4) with an increased cross section and at least one medial region (5) of reduced cross section, such elongated rod (3) having a great axial rigidity, high buckling resistance and low cross rigidity in a single and unbroken part.
(FR)
La présente invention porte sur une tige (tige de liaison) servant à relier le piston à l'extrémité d'un élément élastique de compresseurs linéaires, qui travaillent de préférence à une haute fréquence, composée d'une tige allongée (3) qui a au moins deux régions (4) ayant une section transversale augmentée et au moins une région moyenne (5) de section réduite, cette tige allongée (3) ayant une grande rigidité axiale, une haute résistance au flambage et une faible rigidité transversale en une seule pièce et non brisée.
