FIELD: fluid-pressure actuators. ^ SUBSTANCE: hydraulic circuit comprises hydraulic cylinder whose piston rod is connected with the slide. The compressed fluid is supplied to the hydraulic cylinder from the tank by means of a pump through the four-way three-positioned valve, check valve, and throttle valves interposed between them. The valves are controlled to provided increased pressure in one of the chambers of the hydraulic cylinder which is at a given moment under low pressure in order to decelerate the slide in its moving in both directions when it reaches a given position. The valve for manual control of the flow is interposed between the valves. ^ EFFECT: enhanced quality of working article. ^ 4 cl, 7 dwg |
