IPC: F15B9/08
Filed: 1981-07-24
Abstract: PURPOSE:To quicken excitation-caused output response to an output section, by providing a flow rate control section between a pressure source and each of the output section and an electromagnetic control section for regulating the fluid pessure of the output section, to reduce the unnecessary supply of a pressurized fluid to the pressure source, the output section and the electromagnetic control section. CONSTITUTION:A working fluid from a pressurized fluid source 3 flows to a tank T through the hole 49 of a flow control valve C and chambers 17, 20. When an electromagnet 21 is not energized, a valve element 23 remains stopped where a thrust based  on the fluid pressure diffeence between a passage 33 and a chamber 58 becomes equal  to that of a spring 57. When the electromagnet 21 is energized, a poppet valve 22 is  pushed on a valve seat 39 to heighten the pressure of the chamber 58 to move the valve  element 23 leftward to increase the open area of the hole 49. As a result, the pressure  of the pressure chamber 17 rises so that a piston 37 is moved when the rightward thrust  of the piston has exceeded that of a spring 31. When the sum of the thrust of a spring  32 and that based on the pressure in a valve chamber 19 has exceeded the electromagnetic force, the valve 22 is opened to reduce the open area of the hole 49 by displacement of the valve element 23 to control the pressure of the chamber 17 depending on  the exciting current.

When the measuring range is within the S1, the outputs of the transmitting devices T3 and T2 are at the maximum level, and the output of the transmitting device T1 corresponds to the level. Conversion of the output level is performed by the converter 1 accordingly, and the output in the range of 0-4.8V is supplied to the operator 2.
