ADAPTIVE SHOCK ABSORBER OF SUSPENSION OF TRANSPORT VEHICLE Russian patent published in 2013 - IPC F16F9/16 F16F9/34 F16F9/50 

FIELD: machine building.

SUBSTANCE: shock absorber includes an operating cylinder, inside which a piston with a hollow stock moved in the guide and covered with a cover plate from above is arranged in a movable manner. A limiting sleeve enclosing a stock is installed in the operating cylinder. Upper working through openings are made in lower part of the stock. A tube is rigidly and concentrically fixed inside the stock on the piston. A spring-loaded valve with through lower working openings is installed on lower tube end in a movable manner in axial direction. A closed cavity between a stock and the tube is connected via a pipeline to an inlet cavity of the controlled electromagnetic valve. Shock absorber includes a control unit, an accumulating tank and a controlled hydraulic differential valve with electromagnetic control. The inner tube cavity is connected to the outlet cavity of the electromagnetic valve. Through tangential openings (throttle and valve one) are made on the plunger and the sleeve. A bypass valve is arranged on side cylindrical surface of the tube.
