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 external tube-reservoir fixed in the stock guide and forming an annular cavity with a working cylinder. A piston with a stock is arranged inside the cylinder in movable manner. Upper and lower through working openings are made in the cylinder walls. Bypass valves are installed at the bottom of the cylinder and in the guide. Shock absorber includes a control unit and an adjustable electromagnetic valve of indirect action, which is installed in the tube-reservoir. Main valve pressed with a spring to the housing is arranged in the cavity of the main valve. Spring-loaded valve of direct action, which is rigidly connected to the electromagnet armature connected to the control unit, is arranged in the cavity of the control valve. A restricted closed cavity connecting an above-piston cavity through upper working opening to inlet cavity of electromagnetic valve is formed in annular cavity by means of a closed element. Below-piston cavity is connected via lower working opening through bypass valve to inlet cavity of electromagnetic valves, and annular cavity is connected to its outlet cavity.

EFFECT: improving reliability and simplifying the design of shock absorber.
