Title: Current/pressure converting mechanism
Inventor: KIMURA ATSUSHI
IPC: F15B5/00
Filed: 1989-12-11
Abstract: PURPOSE:To use current effectively so as to make a converting circuit multifunctional by controlling output air pressure as well as the driving current to an actuator through operation of deviation between voltage signal and feed- back signal related to the output air pressure, and through division of deviation signal by output deviation signal. CONSTITUTION:An input processing circuit 23 is composed of a constant current circuit 231, a Zener-diode 232 and an input resistance 233. Source voltage Eb applied to a converting circuit is obtained between a common potential point COM and the Zener-diode 232. Divided current IS is controlled by dividing input current IL by a transistor 24 provided between the common potential point COM and an input terminal 10. By connecting an actuator 25 between the input terminal 10 and the common potential point COM, a flapper 251 is displaced by the current IS. Accordingly, the tolerance of fixed current is widened and the converting circuit is easily made multifunctional.
