| 摘要 | PURPOSE:To obtain a small-sized electricity-displacement transducer free of mechanical loss due to friction, etc., by outputting the quantity of electricity applied to an electronic heat exchanger as variations of nozzle back pressure with the displacement of a bimetal. CONSTITUTION:An electricity-displacement transducer 10 which utilizes Peltier effect generates variations in heat between metallic plates 16 and 17 by a difference between potaintials applied to the electrodes 23 and 24 of a thermoelectric element 11, and a bimetal 19 flexes according to the variations in heat to control opening of a nozzle 20 for jetting air. Then, variations in air pressure at this time are amplfied by a pilot valve 25 to be led out as an output signal POUT, which is supplied to a pressure-electricity transducer 26. Its output IFB is supplied as a feedback signal to a preamplifier 12 through an adder 27. | ||||||
