ELECTRO HYDRAULIC CONVERTER

摘要

FIELD: engines and pumps. ^ SUBSTANCE: proposed device is designed to control high fluid flow rates at higher pressures in fuel feed system and gas turbine control systems. The torque motor shaft accommodates a shutter with a flexible element. Axes of nozzles feeding fluid to the said shutter are arranged parallel to the motor shaft. The shutter pressure forces are transmitted onto the motor bearings are compensated by the motor torque, i.e. shutter turn is proportional to supply current at low motor torques. Possible variations in working fluid pressure onto shutter can be compensated by the position pickup fitted on the motor shaft and connected to the control system controller. ^ EFFECT: higher reliability. ^ 2 cl, 5 dwg
