Abstract:

Assembly comprising a housing having valve and regulator portions, with the housing having an inlet, an outlet and a fluid path extending through the portions. The regulator portion includes a cavity, an inlet connected to the cavity and a outlet connected to the cavity. The regulator portion includes a member selectively covering an area of the cavity and a diaphragm connected to the member for selectively moving the covering member to cover the area. The regulator portion further includes a biasing member biasing the diaphragm to a position such that the member covers the area, with the diaphragm moving against the biasing member when pressure in the first area is above a predetermined amount, thereby forcing the member to cover the area such that fluid is not able to pass through the area and therefore the regulator portion. The valve portion includes a stop valve for stopping gas flow therethrough.
