  • Pressure regulating valve
    Patent number: 6026850
    Abstract: A pressure regulating valve adapted to be interposed between a pressurized liquid supply whose pressure varies and a spray nozzle or other liquid applicator from which the liquid is discharged. The valve, actuated only when the pressure of the incoming liquid exceeds a predetermined minimum level, functions to maintain the flow of liquid fed to the applicator at a substantially constant pressure level regardless of variations in the pressure of the liquid supply, and to cut off flow automatically should the supply pressure fall below an acceptable level.
