FIELD: transport; machine building.SUBSTANCE: invention relates to transport engineering. Electro-hydraulic steering gear for redundant remote control systems contains a hydraulic cylinder with a stem position sensor and a control unit. Control unit has an electro-hydraulic power amplifier, check valve and inlet filter, electromagnetic valve connected by a hydrolysis line to the control chamber of a slide-on/damper valve. In the operating position of the valve of the slide-on/damping valve, the working cavities of the hydraulic cylinder are connected through the operating windows of the slide-on/damping valve with an electrohydraulic power amplifier. Valve plug of the on/off valve has additional radial grooves. In the position of the slide valve in the damping mode, the working cavities of the hydraulic cylinder are interconnected through the working windows of the valve, additional grooves of the spool and throttling radial and axial holes in the spool.EFFECT: higher reliability of the electrohydraulic steering gear is achieved.3 cl, 1 dwg
