Abstract

PURPOSE: To prevent vibrations due to the pressure of a fluid and the mass of a valve and plunger, by suppressing the sudden motion of the valve through the operation of a dashpot.
CONSTITUTION: Once fed with a current, coil 8 generates force pressing plunger 7 down. This action pushes valve 4 via push rod 13 and rod 6. The pressure of a fluid flowing out via outlet 2 depends upon the force operating on valve body 4. Damper room (a) operates as what is called a viscous resistance element suppressing the sudden motion of valve 4. Namely, the sudden motion of valve 4, i.e. the sudden motion of diaphragm 5 generates positive or negative pressure to the atmospheric pressure in damper room (a) and the pressure operates on disphragm 5 in the opposite direction to its motion direction at any time.
