Abstract

An air regulator, which allows precise control of air output pressure, includes a free-floating valve plunger 10 formed by two balls 12A and 12B connected by a bar 14. The valve plunger is free to align itself during operation of the regulator and operates virtually without friction, when opening and closing valve orifices 16 and 18. The ball 12B that contacts the overpressure relief orifice 18 is smaller than ball 12A that contacts the pressure control orifice 16, which is formed as a rubber seat. The air regulator has an over-pressure vent 20 to relieve excess pressure.

Precision Air Regulator

An air regulator, which allows precise control of air output pressure, includes a free-floating valve plunger 10 formed by two balls 12A and 12B connected by a bar 14. The valve plunger is free to align itself during operation of the regulator and operates virtually without friction, when opening and closing valve orifices 16 and 18. The ball 12B that contacts the overpressure relief orifice 18 is smaller than ball 12A that contacts the pressure control orifice 16, which is formed as a rubber seat. The air regulator has an over-pressure vent 20 to relieve excess pressure.

Air is supplied through an inlet 22 and directed through the control orifice 16 to the air outlet 24. The incoming air that enters the outlet chamber through the control orifice 16 increases the pressure within the outlet chamber, so that the forces acting on a diaphragm 26 will overcome the force of adjusting spring 30. The diaphragm will move away from the pressure control orifice 18 to a point where the valve plunger 10 will close the control orifice 16. At this point, the outlet air pressure has reached that level for which adjustment was initially made with adjusting knob 28 and adjusting spring 30.
