Abstract
PURPOSE: To increase the moving stroke of a valve body despite a small solenoid pump applied, by displacing a responsive valve with controlled fluid pressure applied from the solenoid pump and open-close operating a valve device with the displacement of said response valve.
CONSTITUTION: If the first operating signal is fed to a coil 18 in a solenoid pump 12, fluid in the first chamber 23 is forced by a plunger 19 to the second and third chambers 24, 25 further circulated in such sequence that this fluid returns to the first chamber 23 while being applied with prescribed resistance, in this way pressure in the chambers 24, 25 goes up to the first value. Generated pressure in the chamber 24 depresses a responsive mover 16 to open a valve 13, for instance, to supply gas to a pilot burner. When the second operating signal is fed to the coil 18 and pressure in the chamber 25 is flow controlled by a flow control unit, not shownin the drawing, to increase to the second value, a responsive mover 17 slowly lowers to open a valve 15, for instance, to supply gas to a main burner.
