DEVICE WITH CAMS USING INCOMPRESSIBLE FLUID AS STRUCTURAL ELEMENT TO BRING ABOUT THE DEFORMATION AND/OR DISPLACEMENT OF CAM PROFILES, IN ORDER TO VARY ENGINE VALVE TIMING

摘要

The device described comprises a cam type with a deformable contour and / or moved using a fluid (liquid) incompressible under pressure with calibrated channels and / or throttling passages and it allows to advance or retard the time of the opening and / or closing each of the valves of an internal combustion engine. The operation of the device is based on the effect of a fluid under pressure controlled by throttling passages and acting inside the cam on the overall structure thereof or on the resilient elements moving with it.
