Title: PRESSURE DEVICE FOR EXERTING A HOLDING FORCE ON A TRANSMISSION DEVICE AND ENGINE PROVIDED WITH SUCH A DEVICE
Abstract:
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.
