Abstract[English]
A piston compressor (1) has a cylinder (3) with a compartment (7) connected with a supply duct (5) and a delivery duct (6) for the gas and elastically supported so as to be able to oscillate along a longitudinal axis (A); a piston (4) movable with a reciprocating motion (3) so as to compress the gas; an actuator (15) for generating the reciprocating motion of the piston (4) and the cylinder (3) along a longitudinal axis (A); a lubrication duct (17) extending, at least partly, across the cylinder (3) so as to supply lubrication oil into an interstice between the piston (4) and the cylinder (3); and a Tesla valve (16), which is integral with the cylinder (3), is immersed in a lubrication oil bath and has an inlet opening (19) and an outlet opening (20) connected to the lubrication duct (17), and a valvular conduit (18) extending between the inlet opening (19) and the outlet opening (20) in a direction parallel to the given axis (A).[French]
L'invention concerne un compresseur à piston (1) comprenant un cylindre (3) avec un compartiment (7) relié à un conduit d'alimentation (5) et un conduit de distribution (6) pour le gaz et supporté élastiquement de manière à pouvoir osciller le long d'un axe longitudinal (A) ; un piston (4) qui peut se déplacer avec un mouvement de va-et-vient (3) de manière à comprimer le gaz ; un actionneur (15) destiné à générer le mouvement de va-et-vient du piston (4) et du cylindre (3) le long d'un axe longitudinal (A) ; un conduit de lubrification (17) s'étendant, au moins en partie, en travers du cylindre (3) de manière à fournir de l'huile de lubrification dans un interstice entre le piston (4) et le cylindre (3) ; et une valve de Tesla (16), qui est d'un seul tenant avec le cylindre (3), est immergée dans un bain d'huile de lubrification et présente une ouverture d'entrée (19) et une ouverture de sortie (20) reliées au conduit de lubrification (17), et un conduit valvulaire (18) s'étendant entre l'ouverture d'entrée (19) et l'ouverture de sortie (20) dans une direction parallèle à l'axe donné (A).
