Fluid regulator having integral fluid purge mechanism

A fluid regulator comprising:

• a housing that defines an internal flow path and an internal regulating path that intersects the internal flow path;
• an operable seal that separates the internal regulating path into a poppet portion and a regulating portion, wherein the poppet portion intersects the internal flow path;
• a poppet valve that is disposed within the internal regulating path and the internal flow path, wherein the poppet valve in a standard state defines a selectively regulated flow of fluid through the internal flow path, wherein a poppet biasing force biases the poppet valve to a closed position;
• a regulating interface positioned within the internal regulating path, wherein the regulating interface operates to overcome the poppet biasing force to define the selectively regulated flow of fluid, wherein the regulating interface includes a biasing spring that engages the operable seal wherein operation of a regulating member of the regulating interface defines a predetermined spring force of the biasing spring;
• and
• a fluid purge mechanism positioned within the regulating interface, wherein the fluid purge mechanism manipulates the poppet valve to define a maximum operating position that defines a purging flow of fluid through the internal flow path, wherein the regulating interface includes a threaded bolt that rotates about a central rotational axis and within the threaded bolt, purge mechanism is positioned along the central rotational axis and within the threaded bolt, wherein the fluid purge mechanism is a pin that slidably operates within the threaded bolt to engage a bypass plate, wherein the bypass plate adjusts the predetermined spring force to a bypass force that places the poppet valve in the maximum operating position, wherein the biasing spring is positioned between the bypass late and a spring-force transfer member that engages the operable seal.

A fluid regulator comprising:

• a housing that defines an internal flow path and an internal regulating path that intersects the internal flow path;
• an operable seal that defines a boundary of the internal flow path and separates a portion of the internal regulating path from the internal flow path;
• a poppet valve that is disposed within the internal regulating path and the internal flow path, wherein the poppet valve in a standard state is configured to define a selectively regulated flow of fluid through the internal flow path;
• a threaded regulating interface positioned within the internal regulating path, wherein the threaded regulating interface adjusts a spring force exerted against the operable seal to define a rate of the selectively regulated flow of the fluid;
• and
• a fluid purge mechanism slidably disposed within the threaded regulating interface, wherein the fluid purge mechanism manipulates the spring force independent of the threaded regulating interface to define a maximum operating position that defines a purging flow of fluid through the internal flow path.
