ELECTROHYDRAULIC SPEED GOVERNOR FOR HYDRAULIC TURBINE Abstract of the Disclosure An electrohydraulic governor comprising a speed respon- sive element connected to a shaper of an electrical signal representing a given control law, connected with an input of an electromechanical servosystem coupled with a fixing means to fix the position of the distributor and with an input of an electrohydraulic servosystem converting a signal of the external hydraulic turbine control and a signal representing the given control law to a respective opening of the distri- butor. The electrohydraulic system comprises a summing amplifier connected to an electromechanical transducer coup- led with hydraulic actuator having a slide valve and a servomotor and coupled through an initiating and a main slide valve with the main servomotor of the distributor. The main servomotor is also coupled through an electromecha- nical feedback means with the summing amplifier. The slide valve of the hydraulic actuator is set with respect to its bushing in a position displaced with respect to its central position in the absence of the power supply of the governor in the direction of action of the main servomotor to open the distributor. The fixing means of the control device is made in the form of a double-arm lever mounted with a clearance with respect to the initiating slide valve, one arm of the lever being connected through a mechanical transmission with the rod of the main servomotor, while the other arm is coupled with an output self-braking reduction gear box of the electromechanical servosystem.
