SHOCK ABSORBER Russian patent published in 2015 - IPC F16F9/516 F16F9/49 F16F9/342 F16F9/18 

FIELD: machine building.

SUBSTANCE: shock absorber contains a cylinder with work fluid. The piston is inserted in the cylinder and separates the cylinder to two chambers. The piston rod is connected with the piston. The damping valve is installed in the first channel. The through section regulation mechanism is installed in the piston and regulates the through section of the second channel based on the piston rod position. The damping force decreases for tension and increases for compression in the set rod position at large extension. The damping force increases for tension and decreases for compression in the set rod position at small extension. In the shock absorber under the second option the damping force decreases for tension and compression in set rod position at small extension. In the shock absorber under the third option the damping force decreases for tension and compression in set rod position at large extension. The damping force increases for tension and decreases for compression in the set rod position at small extension. The shock absorber under the 4th option is installed between the wheel and body of the vehicle. Mechanism regulating the vehicle height is installed in parallel with the shock absorber.

EFFECT: extension of dampening characteristics.
