Solenoid flow control valve device

Abstract

Abstract PURPOSE:To improve operative durability of a valve, by both inserting a sleeve onto a rotary shaft and integrally forming a rotary valve to an end part, exciting a permanent magnet provided to the sleeve with an electromagnetic coil, rotating the rotary shaft and selecting an input and output port through the rotary valve. CONSTITUTION:When an electric current is not conducted to flow in electromagnetic coils 33, 34, a rotary valve 24 is held to an initial position, and a communication hole 25 is opened while a communication hole 26 is closed, consequently the atmospheric air is supplied to an output port 13. If the coils 33, 34 are electrically conducted and excited, a rotary shaft 22 is rotated, and the rotary valve 24 is turned to decrease an opening of the hole 25 while increase an opening of the hole 26, consequently a negative pressure in accordance with an opening of the both holes 25, 26 is supplied to the output port 13. The opening of the communication holes 25 and 26 is arranged in a relation reversely obtained to each other.
