Abstract

Cette invention concerne un dispositif de rattrapage de jeu hydraulique pour soupapes, monté dans un culbuteur et comprenant des pièces formant un cylindre et un piston, guidées à coulissement l'une dans l'autre à l'intérieur d'un alésage prévu dans le culbuteur et fermé à une extrémité. Pour l'alimentation en huile, il est prévu un perçage qui part de l'axe du culbuteur et qui débouche vers une extrémite de l'alésage, dans laquelle il est prévu un interstice annulaire permettant à l'huile de parvenir directement sur la paroi extérieure du piston. Celui-ci présente dans cette partie des orifices pour le passage de l'huile ou d'autres moyens permettant à l'huile de parvenir dans une chambre de pression à l'intérieur de la pièce formant cylindre. Cet agencement est utilisable sur les moteurs à combustion interne à commande des soupapes par culbuteurs.This invention relates to a valve hydraulic backlash adjuster, mounted in a rocker arm and comprising parts forming a cylinder and a piston, slidably guided into one another within a bore provided in the rocker arm. and closed at one end. For the oil supply, a bore is provided which starts from the rocker arm axis and which opens out towards an end of the bore, in which an annular gap is provided allowing the oil to reach the wall directly. outside of the piston. The latter has in this part orifices for the passage of oil or other means allowing the oil to reach a pressure chamber inside the part forming the cylinder. This arrangement can be used on internal combustion engines with rocker arm valve control.
