Closed cylinder tilt module

摘要

A tilt mechanism for adjusting an angular position of an automotive steering column. The tilt mechanism includes an adjustment cylinder assembly having a fluid power cylinder, a fluid conduit and a valve. The adjustment cylinder assembly is configured in a closed-loop manner such that the fluid that is displaced from one side of the cylinder is directed to the other side of the cylinder. The valve is employed to inhibit the flow of fluid between the sides of the cylinder to thereby lock the tilt mechanism in a desired position.
