A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, and a retaining member, the valve housing being configured to pass fluid through the fluid conduit, and a flexible diaphragm comprising a flexible material having resiliency, wherein the retaining member and the fle
A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, and a retaining member, the valve housing being configured to pass fluid through the fluid conduit, and a flexible diaphragm comprising a flexible material having resiliency, wherein the retaining member and the flexible diaphragm are configured so that the retaining member retains a portion of the flexible diaphragm so as to use the resiliency of the flexible material to bias the flexible diaphragm against the valve seat to a closed position of the self-sealing valve to provide a self-seal of the fluid conduit, and to facilitate movement of the flexible diaphragm under a fluid bias against a first side of the flexible diaphragm in a first direction away from the valve seat to an open position, and wherein the retaining member and the flexible diaphragm are configured so that the self-sealing valve can be contacted to move a portion of the flexible diaphragm away from the valve seat to the open position.

1. A fluid controller configured to supply fluid to a bladder including a first chamber, the fluid controller comprising: a housing;a pump located at least partly within an interior of the housing and configured to provide fluid to the first chamber; anda plurality of self sealing valves fluidly coupling an interior of the housing to the first chamber;wherein at least two of the plurality of self sealing valves are biased open to provide a fluid path between the interior of the housing and the first chamber during inflation of the first chamber;wherein the housing includes a wall separating the interior of the housing from the first chamber,wherein the wall includes a plurality of orifices each configured to be sealed by one of the plurality of self sealing valves, respectively,wherein a first plurality of orifices and respective self-sealing valves are employed during inflation, andwherein a single self-sealing valve and orifice is employed for fluid release. 2. The fluid controller of claim 1, wherein the single self-sealing valve and orifice employed to release fluid from the first chamber is also included in the plurality of self sealing valves employed during inflation of the first chamber. 3. The fluid controller of claim 2, wherein a minimum of at least three self sealing valves are included in the plurality of valves employed during inflation of the first chamber. 4. The fluid controller of claim 1, wherein the fluid controller is located at least partly within a profile of the bladder. 5. The fluid controller of claim 4, wherein the fluid controller is included in an inflatable mattress. 6. The fluid controller of claim 5, wherein the inflatable mattress includes a plurality of chambers including the first chamber, and wherein each of the plurality of valves is fluidly coupled to each of the plurality of chambers. 7. The fluid controller of claim 1, further comprising a valve actuator configured to open the single self-sealing valve. 8. The fluid controller of claim 7, wherein the valve actuator is manually operated without aid of electricity. 9. The fluid controller of claim 7, wherein the valve actuator is electrically operated. 10. The fluid controller of claim 1, wherein each of the plurality of self sealing valves includes a flexible diaphragm. 11. The fluid controller of claim 1, wherein the total area provided by the first plurality of orifices is at least twice a total area provided by the single orifice. 12. The fluid controller as claimed in claim 1, wherein the housing is at least partly recessed within a wall of the first chamber. 13. A fluid controller configured to supply fluid to a bladder including a first chamber, the fluid controller comprising: a housing;a pump located at least partly within an interior of the housing and configured to provide fluid to the first chamber; anda plurality of self sealing valves fluidly coupling an interior of the housing to the first chamber;wherein during inflation each of the at least two of the plurality of self sealing valves is biased open solely by fluid pressure provided by the pump to provide a fluid path between the interior of the housing and the first chamber. 14. A fluid controller configured to adjust fluid pressure in an inflatable comfort device including an inflatable bladder, the fluid controller comprising: a housing;a pump located at least partly within an interior of the housing and configured to provide fluid to the inflatable bladder; anda plurality of valves fluidly coupling an interior of the housing to the bladder;wherein the housing includes a housing wall including a plurality of openings each associated with one of the plurality of valves, respectively,wherein each opening defines a cross-sectional area of a fluid pathway from the interior of the housing to the bladder, respectively, andwherein a total cross-sectional area provided by at least one opening selected from the plurality of openings for use during inflation is greater than a total cross-sectional area provided by at least one opening selected from the plurality of openings for use during deflation. 15. The fluid controller of claim 14, wherein the total cross-sectional area for use during inflation is at least twice the total cross-sectional area for use during deflation. 16. The fluid controller of claim 15, wherein the at least one opening selected for use during inflation includes at least two openings each associated with one of the plurality of valves, respectively. 17. The fluid controller of claim 15, wherein a ratio of the total cross-sectional area for use during inflation to the total cross-sectional area for use during deflation is substantially 2:1. 18. The fluid controller of claim 14, wherein at least two of the plurality of valves are biased open during an inflation of the inflatable bladder by the fluid provided by the pump. 19. The fluid controller of claim 18, wherein at least one of the plurality of valves is biased open with a valve actuator during deflation of the inflatable bladder. 20. The fluid controller of claim 14, wherein each of the valves includes a self sealing valve having a diaphragm, respectively. 21. The fluid controller of claim 20, wherein each diaphragm includes a flexible diaphragm, respectively. 22. The fluid controller as claimed in claim 14, wherein the housing is at least partly recessed within a wall of the inflatable bladder. 23. A fluid controller configured to adjust fluid pressure in an inflatable comfort device including an inflatable bladder, the fluid controller comprising: a housing including a housing wall having a plurality of openings, each opening respectively associated with one of a plurality of valves fluidly coupling an interior of the housing to the inflatable bladder, wherein each opening and respective valve defines a respective cross-sectional area of a fluid pathway from the interior of the housing to the inflatable bladder;a pump located at least partly within an interior of the housing and configured to provide fluid to the inflatable bladder;wherein a total cross-sectional area provided by a plurality of valves and respective openings during inflation is substantially different from a total cross-sectional area provided by at least one valve in combination with the at least one opening during deflation. 24. The fluid controller as claimed in claim 23, wherein the housing is at least partly recessed within a wall of the inflatable bladder.
