A Operation
Fiqure22 shows a cross section of the water inlet valve in its ciosed position and Figure 23 shows it in its open
position. The water pressure al B and C has equalized because the bleed hole opening permits water to flow from
B to C Pressure at A is atmospheric (Figure 22)
The valve remains dosed because the higher water line pressure al C is greater than the atmospheric pressure at
A When the solenoid coil is energized by the timer, the plunger is withdrawn from the diaphragm opening Water
in comDariment C wiil then escape through the diaphragm opening causing the pressure in the comparimenl to fall
to almost almoshpheric pressure. The higher water line pressure al B forces the diaphragm away from its seal,
opening the valve Water then flows through the screen under the diaphragm and out the valve.
When the solenoid releases the plunger, the hole in the center of the diaphragm is sealed. Water then flows through
the bleed hold in the diaphragm until the pressure in compartment C rises to water Ime pressure
the diaphragm at water line pressure in compartment C is greater than the area al water line pressure in compartment
B, the diaphragm is forced dosed. The pressure al A is always lower than full ime pressure because water passing
through the valve is escaping to the open air.
