ことを特徴とする電空変換器。 An electro-pneumatic converter that controls pneumatic output in response to an input current, comprising: a drive means for driving a first flapper in response to an input current; and a drive means provided opposite to one end of the first flapper, A first nozzle whose one end constitutes a nozzle flapper mechanism, a back pressure chamber into which the back pressure of the first nozzle is input, an exhaust valve that performs exhaust, and an air supply valve that engages with one end of the exhaust valve. a pilot relay that amplifies the back pressure of the first nozzle and outputs it as output pressure; a spring having one end fixed to the other end of the exhaust valve; a second flapper attached to the other end of the spring; The same pressure as the output air pressure of the control relay is input to a second nozzle, which has one end facing the two flappers and the other end is open to the atmosphere and is attached to the back pressure chamber and forms a nozzle-flapper mechanism with the second flapper. 1. An electro-pneumatic converter comprising: a feedback bellow, and feedback means for feeding back a force signal of the feedback bellow to an input side.
