Abstract

A valve (500) comprising a member (514) subject to a first force operative to keep said value closed, said member being sensitive to an index pressure (P1); and an outlet (516) at a second pressure (P2), said index pressure (P1) providing a second force in opposition to said first force when a differential between said second pressure (P2) and said index pressure (P1) is provided to said member (514): and opening the valve when said second pressure (P2) is sufficiently less than the index pressure (P1) to overcome the first force, and a vent (520) operably associated with the member (514), said vent (520) opening when said valve is opened.

Claims

AMENDED CLAIMS [Received by the International Bureau on 26 January 2005 (26.01.05)]
1. A valve comprising a member subject to a first force operative to keep said valve closed and a first pressure associated with said valve, said member being sensitive to an index pressure; and an outlet at a second pressure, said index pressure being distinct from said first pressure and said second pressure and providing a second force in opposition to said first force when a differential between said second pressure and said index pressure is provided to said member; and opening the valve when said second pressure is sufficiently less than the index pressure to overcome the first force, and a vent operably associated with the member, said vent opening when said valve is opened.
2. The valve of claim 1 and said member providing the first force.
3. The valve of claim 1 wherein said valve closes under action of said second pressure when said index pressure provides said second force to said member of a magnitude less than that of said first force, and wherein said vent closes.
4. The valve of claim 1 wherein said valve closes under action of said second pressure when said second pressure on said member is substantially equal to said index pressure, and wherein said vent closes.
5. The valve of claim 1 and said member comprising a stop and a plug connected to the stop.
6. The valve of claim 5 wherein said vent is associated with the plug.
7. The valve of claim 5 wherein said plug comprises a frustoconical member extending therefrom, the vent associated with the frustoconical member.
8. The valve of claim 7 wherein said vent comprises a slit in a distal end of the frustoconical member.
9. The valve of claim 1 wherein said member comprises a diaphragm.
