Abstract
PURPOSE: To continuously control pressure proportionally to current by a pressure controller and remotely control the pressure with high responsibility by connecting an electromagnetic drive unit to a governor having inlet and outlet.
CONSTITUTION: Uniform magnetic field is formed in an air gap between the magnetic pole of a center pole 21 and the magnetic pole of a yoke 22 to occur downward force FK when a coil 20 in the magnetic field is energized. FK=B.I.l becomes where B represents magnetic flux density, I current and l the length of the coil. This force is operated through a bobbin 16 to a diaphragm 2 together with the tension FS of the spring 15. With the governor designed so that the pressure receiving area AD of the diaphragm 2 is equal to the opening area AV of the valve seat 14, the governor secondary pressure becomes P2=F/AV. Accordingly, since the secondary pressure P2 can be varied in response to the current flown through the coil 20, it can remotely be controlled with high responsibility by the pressure controller.
