Title (EN) HYDRAULIC TAPPET
(FR) POUSSOIR HYDRAULIQUE
Abstract:
(EN) Described is a hydraulic tappet of an internal combustion engine, comprising a bridge (2) configured to control the movement of two valves and having a central portion (2c) and two side arms (2a, 2b) designed to engage with respective rods of respective valves, the bridge (2) having at the central portion (2c) a blind cylindrical cavity (4) having an inner wall (4a), a bottom wall (4f) and an upper outlet (6); a plunger (7) engaged slidably inside the cavity (4) and emerging from it at least partly at its upper outlet (6), the plunger (7) being configured for engaging at the top with a respective element for pushing the tappet.
(FR) L'invention concerne un poussoir hydraulique d'un moteur à combustion interne. Le poussoir hydraulique comprend un pont (2) configuré pour commander le mouvement de deux soupapes et comporte une partie centrale (2c) et deux bras latéraux (2a,2b) conçus pour entrer en prise avec des tiges respectives des deux soupapes. Le pont (2) comporte au niveau de la partie centrale (2c) une cavité cylindrique borgne (4) ayant une paroi interne (4a), une paroi inférieure (4f) et une sortie supérieure (6). Un piston (7) vient en prise de manière coulissante à l'intérieur de la cavité (4) et sort de celle-ci au moins partiellement au niveau de sa sortie supérieure (6), le piston (7) étant configuré pour venir en prise au niveau de la partie supérieure avec un élément respectif pour pousser le poussoir.
