US Patent 9982738 Variable load control system in a hydraulic device

A hydraulic device includes a tubular housing, inside of which a rod is jointly attached to a piston separating upper and lower areas which hold hydraulic fluid so that, as the piston and rod move, the piston and the rod move together relatively and axially inside the tubular housing, displacing the hydraulic fluid inside the tubular housing, flowing from one of the upper and lower areas to the other of the upper and lower areas, and thus changing the respective volumes inside the upper and lower areas. The hydraulic device further includes a modular mechanism located inside the lower area that regulates shock absorption at a maximum level of compression of the hydraulic device, as well as in other relative positions.
