FIELD: machine building.
SUBSTANCE: invention relates to field of mechanical oscillations antihunting, particularly in suspensions of vehicles. Pneumatic shock absorber contains casing with fixation facilities to one part of object. In casing it is installed hollow piston (3) with fixation facilities to other part of object. Piston (7) is connected by bar to casing. Switching-valve package allows spring-loaded gate, installed with ability of communication to each other of adjacent head ends. Control assembly of gate contains electronic commutator, connected at inlet to electronic sensors, and at outlet to drive of gate of switching-valve package. Bar is implemented as hollow. In bar there are implemented drain ports with all head ends. Gate in the form of hollow cylinder is located nearby drain port of middle head end.
EFFECT: design simplification, refinement of damping.
