Abstract:
A double directional valve and flow restriction combination, comprising:a housing for receiving a gas; an orifice poppet slidably mounted between first and second positions in said housing, said orifice poppet having an air flow orifice for flow of the gas through said orifice poppet; a poppet bias mechanism normally biasing said orifice poppet in said first position; a support provided in said housing; a taper cone carried by said support and disposed adjacent to said air flow orifice; wherein said air flow orifice approaches said taper cone as said orifice poppet moves from said first position toward said second position; wherein proximity of said air flow orifice with said taper cone and restriction of flow of the gas through said air flow orifice is directly proportional to the pressure of the gas; a first valve carried by said support in said housing; and a second valve carried by said support in said housing in spaced-apart relationship to said first valve.
