ABSTRACT:
In a pneumatic pressure regulator comprising a ported housing having an internal bore, within the bore a spring-pressed piston mounted for reciprocation between advanced and retracted positions, and valve means associated with the piston and operative to direct the flow of air to the respective housing ports; the improvement comprising a housing the bore of which is inwardly tapered in the direction of spring-pressed piston retraction. This results in decreased friction, and improved hysteresis characteristics.
