Telescopic shock absorber for motor vehicle - has decreasing damping force provided by valve body moving against force of annular spring assembly

摘要

The assembly consists of a cylinder closed by a lid at the top. The piston has valves operating in axially opposite directions. The opposite cylinder end has axial openings (118), covered with a disc valve (119) loaded by a conical spring (120). The cylinder space (107) is separated from the equalising space (115) with which it communicates via openings (127) above the disc valve (125), and via openings (129) below the disc valve. Openings (118) in the cylinder end (103) serve as filling openings during the pulling phase, for the cylinder space. During the compression phase oil flows to the space above the disc valve.
