Abstract

L'invention concerne un bloc hydraulique destiné à un moteur à combustion interne équipé d'une commande de soupapes électrohydraulique, comprenant ‑ un boîtier hydraulique (2) possédant un orifice de logement (33), ‑ un guide de piston (32) maté avec l'orifice de logement et, guidé dans celui-ci, un piston de pompe (8) mobile dans le sens longitudinal, ‑ et un suiveur de came réalisé sous la forme d'un poussoir pour transmettre une levée de la came au piston de pompe. Selon l'invention, le poussoir est réalisé sous la forme d'un poussoir à coupelle (23, 23') qui possède une face d'attaque de came et une chemise de coupelle (24) et qui est guidé dans un guide de poussoir (25) du boîtier hydraulique de façon à pouvoir se déplacer dans le sens longitudinal.
