Abstract
A fluid regulator includes a housing that includes a flow path extending from an inlet to an outlet. A poppet valve is disposed within the flow path and that selectively allows a flow of fluid from the inlet to the outlet. A regulating interface adjusts a spring tension that is exerted toward the poppet valve. The regulating interface defines a boundary of the flow path and the spring tension defines a regulated flow of fluid through the flow path from the inlet to the outlet. A fluid purge mechanism is positioned within the regulating interface. The fluid purge mechanism adjusts the boundary of the flow path and manipulates the poppet valve to a maximum operating position to define a purging flow of the fluid from the inlet to the outlet.
