Title (EN) PRESSURE DEVICE FOR EXERTING A HOLDING FORCE ON A TRANSMISSION DEVICE AND ENGINE PROVIDED WITH SUCH A DEVICE
(FR) DISPOSITIF PRESSEUR POUR EXERCER UN EFFORT DE MAINTIEN SUR UN DISPOSITIF DE TRANSMISSION ET MOTEUR MUNI D'UN TEL DISPOSITIF
Abstract:
(EN) The invention relates to a pressure device (10) for exerting a holding force on a transmission device likely to move transversely in an engine block during an engine cycle, the pressure device (10) comprising a piston (21) moving in a chamber (22) filled with a fluid and defined by a jacket (23), a check valve between the chamber and a fluid source, the fluid having a first pressure and the check valve making it possible to maintain the fluid of the chamber at a pressure no lower than the first pressure, and at least one calibrated leakage opening for the fluid retained in the chamber. According to the invention, the calibrated leakage opening is provided with a check valve calibrated to a second pressure higher than the first pressure. The invention likewise relates to an engine provided with such a pressure device.
(FR) L'invention porte sur un dispositif presseur (10) pour exercer un effort de maintien sur un dispositif de transmission susceptible de se déplacer transversalement dans un bloc moteur au cours d'un cycle moteur, le dispositif presseur (10) comprenant un piston (21) évoluant dans une chambre (22) emplie d'un fluide et définie par une chemise (23), un clapet anti-retour entre la chambre et une source de fluide, le fluide présentant une première pression et le clapet anti-retour permettant de maintenir le fluide de la chambre à une pression supérieure ou égale à la première pression, au moins un orifice de fuite calibré du fluide retenu dans la chambre. Selon l'invention, l'orifice de fuite calibré est muni d'un clapet de retenue taré à une seconde pression supérieure à la première pression. L'invention porte également sur un moteur muni d'un tel dispositif presseur.
