Abstract
A method and apparatus for a pressure regulator to control the flow of gases through the regulator and control the escape of gases from the regulator base to the regulator bonnet. The pressure regulator contains a flexible rubber diaphragm contacting a flexible diaphragm plate. The flexible diaphragm plate flexes upward or downward in response to changes in the control pressure and engages a pintle valve that controls the entry of gases to the pressure regulator. A system of chambers and passages controls the escape of gases by funneling escaped gases from a catch chamber to an exhaust port.
