摘要: An electromagnetically controlled hydraulic servo-control valve includes a hydraulic slide activated by an electromagnet with a plunger. The distributed pressure hydraulically pushes the slide and the plunger toward each other. Constrictions in the hydraulic conduits attenuate oscillations. The plunger and the slide have slightly different cross-sections to provide a control loop for the distributed pressure, affecting the position of the side. Use of a polarized electromagnetic supplied by a current that ranges from a negative value to a positive value doubles the regulating capacity. To prevent hysteresis of the pressure curves, as a function of the current, the electro-magnet can be supplied by a pulsed current or an alternating current with a continuous component. The servo-control valve might be used in connection with an automatic gear box control.
