FIELD: engines and pumps.
SUBSTANCE: invention can be used in the internal combustion engines. Method of shock-absorbing of impact loads is designed for the gas distributing valve of the internal combustion engine and is performed by the hydraulic drive system of the gas distributing valve of the internal combustion engine comprising control system of gas distributing valve drive, gas distributing valve (7), slide valve (11) to control liquid flow, hydraulic accumulator (6) charged with work liquid, and piston (14) of the gas distributing valve drive. During movement of the gas distributing valve (7) from closed position to opened position, and vice versa the control system of the gas distributing valve drive (7) tracks the current position and speed of the gas distributing valve (7), determines time of start of movement braking of the gas distributing valve (7), and by the slide valve (11) of liquid flow control ensures the work liquid supply from the hydraulic accumulator (6) in the piston (14) cavity of the gas distributing valve drive, ensuring movement of the gas distributing valve (7) in the specified direction. Further the system by means of the slide valve (11) changes direction of the work liquid supply from the hydraulic accumulator (6) in the piston (14) cavity of the gas distributing valve drive, ensuring movement of the gas distributing valve in opposite direction, as result speed of the gas distributing valve (7) is reduced to value ensuring shockless contact when the gas distributing valve (7) achieves the final point of movement. Then the control system returns the slide valve (11) for liquid flow control to the previous position, and the work liquid from the hydraulic accumulator (6) ensure final setting of the gas distributing valve (7) to the specified position.
EFFECT: reduction of the impact loads on valve.
