Co-axial solenoid and pressure regulator for diaphragm valve
First Claim
Patent Images
1. A valve assembly, comprising:
- a diaphragm valve;
a pressure regulator having a first coil spring and 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; and
a solenoid having a second coil spring and mounted on the pressure regulator so that an axis of the solenoid extends through the first coil spring of the pressure regulator, the solenoid being operatively coupled to the diaphragm valve through the pressure regulator for opening and closing the diaphragm valve.

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.
