  • Co-axial solenoid and pressure regulator for diaphragm valve
    Patent number: 7806382
    Abstract: A valve assembly comprises a diaphragm valve, a pressure regulator and a solenoid. The pressure regulator is operatively coupled to the diaphragm valve for maintaining a predetermined pressure in water exiting the diaphragm valve despite fluctuations in the pressure of water entering the diaphragm valve. The solenoid is mounted on the pressure regulator so that a plunger axis of the solenoid extends through a coil spring of the pressure regulator. The solenoid is operatively coupled to the diaphragm valve through the pressure regulator for opening and closing the diaphragm valve.
