FORCE MOTOR DISPLACEMENT DEVICE AND PRESSURE REGULATING DEVICE USING THIS FORCE MOTOR DISPLACEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a force motor displacement device which can perform high speed/high accuracy control without causing displacement in the coil even if impact is applied from outside to a moving coil of a transducer which sets input pressure to a booster. SOLUTION: A detection circuit 13, a phase inverter 14, and an amplifier 15 are connected to a coil of a transducer 11 which sets up input pressure Pinto a booster 10, and output of the amplifier 15 is supplied to an input terminal of another side of an adder 12 into which a command signal is input.
