Patent ID: 6971403

Claim:
A pressure regulator comprising: a housing having a bore, the housing including an inlet port and an outlet port fluidly connected to the bore; a plug located within the housing and dividing the bore into an upper chamber and a lower chamber, the plug including a pair of parallel through holes, the plug further including a channel fluidly connected to the inlet port, the channel including a valve seat fluidly connecting the inlet port to the bore; a yoke extending through the plug and being adapted to move relative to the plug, the yoke being connected to a valve, the valve being adapted to selectively cover the valve seat, the yoke including a pair of parallel legs extending through the through holes of the plug, the valve being interconnected to the legs adjacent the valve seat; a diaphragm located in the upper chamber, the diaphragm being connected to the yoke; a vent fluidly connecting the upper chamber to the lower chamber; and a biasing member biasing the yoke through the plug such that the valve does not cover the valve seat; and wherein the diaphragm is configured to move against the biasing member when pressure in the lower chamber is above a predetermined amount, thereby forcing the yoke to slide within the plug and the valve to cover the valve seat such that fluid is not able to pass through the inlet port of the housing and the channel of the plug.
