Abstract

The hydraulic valve comprises a pump driven servo member, a collecting tank and a discharge valve. A control valve can be moved from a neutral position into a position connecting the servo member to the collecting tank or a position connecting the servo member via a supply line to the pump. In its neutral position and the position connecting tank andservo member, the control valve is connected via the discharge valve to the tank. The supply line is connected via a bypass pipe with a regulating valve to the pressure pipe, bypassing the control valve and the discharge valve. The regulating valve includes a throttle member and a non-return valve.
