FIELD: machine building. ^ SUBSTANCE: damper consists of cylinder chamber filled with fluid, of piston installed inside cylinder chamber, of rod connected to piston and of accumulator. The accumulator facilitates generation of damping force produced by the piston rod due to fluid flow from the side of compression in the cylinder chamber. One coil of spiral damping groove is formed on internal periphery of the cylinder chamber within the ranges of piston stroke. Width of the damping groove is constant along its whole length. Depth of the damping groove is gradually diminishes along the spiral in the direction whereto the piston rod is pushed out. The length of the piston along axial line is less, than pitch of the damping groove. ^ EFFECT: simplified design and more efficient control of damping force of damper. ^ 6 cl, 7 dwg |
