FIELD: machine building. ^ SUBSTANCE: damper of hydraulic shock consists of swing-check gate with shutting component - disk installed in its case. Behind it there are arranged an angular differential automatic control valve consisting of vertically installed case and a seat located in the lower part of the case, of a rod composed of two sub-plungers with a shutting-off component, of a discharge pipe and of a pulse pipe connecting a cavity above the rod with a pipeline to the shutting-off component of the swing-check gate. A receiving chamber is located above the case of the control valve. The rod is composed of two parts interconnected with a pin and lock-nuts. The plunger facilitates control of flow section area between the plungers and their accurate positioning relative to flow openings. In its upper part the case of the control valve consists of two cylinder cartridges intercommunicated by means of side openings for working medium running. A receiving chamber for working medium discharge is located above the case of the control valve. ^ EFFECT: expanded functionality and increased rate of damping direct wave of working medium. ^ 2 cl, 2 dwg |
