Abstract
Disclosed is a fire extinguisher comprising a container separated into two compartments, one compartment containing pressurized gas and the other containing an extinguishant. The container has a valve to release the extinguishant, which is forced from the container when the bladder is expanded by the pressurized gas. The center of the bladder has a force absorbtion means for protection against the impact of the bladder striking the inner wall of the container. The force absorbtion means has two disks clamped together to retain an annular bead of the bladder.
Claims17
A fire suppressant mechanism comprising a container;
- a flexible bladder subdividing the container into two separate chambers;
- a liquid fire extinguishant occupying one of the chambers;
- a gaseous pressurizing agent occupying the other chamber to bias the bladder in the direction of the liquid fire extinguishant;
- a liquid discharge valve communicating with said one chamber, whereby when the valve opens the pressurizing agent acts on the bladder to discharge the liquid fire extinguishant through the open valve;
- and rigid force absorber means carried by a central area of the bladder to impact against one end of the container for limiting bladder motion without damaging the bladder material;
- wherein the bladder has a central annular bead therein;
- said rigid force absorber means comprising two rigid plates clamped together, said plates having annular confronting grooves mated to said annular bead for securely retaining the plates on the bladder.
A fire suppresent mechanism comprising a container;
- a flexible bladder subdividing the container into two separate chambers;
- a liquid fire extinguishant occupying one of the chambers;
- a gaseous pressurizing agent occupying the other chamber to bias the bladder in the direction of the liquid fire extinguishant;
- a liquid discharge valve communicating with said one chamber, whereby when the valve opens the pressurizing agent acts on the bladder to discharge the liquid fire extinguishant through the open valve;
- and rigid force absorber means carried by the central area of the bladder to impact against one end of the container for limiting bladder motion without damaging the bladder material;
- and further comprising a guide structure located on the movement axis of the bladder for slidable engagement with the rigid force absorber means.
A fire suppressant mechanism comprising an elongate container;
- a flexible bladder subdividing the container into two separate chambers;
- a liquid fire extinguishant occupying one of the chambers;
- a gaseous pressurizing agent occupying the other chamber to bias the bladder in the direction of the liquid fire extinguishant;
- the bladder having an interface portion facing generally axially toward the one chamber and extending substantially entirely across the cross section of the container;
- a liquid discharge valve communicating with said one chamber, whereby when the valve opens the pressurizing agent acts on the bladder to discharge the liquid fire extinguishant through the open valve;
- rigid force absorber means carried by a central area of the bladder to impact against one end of the container for limiting bladder motion without damaging the bladder material;
- and a flush valve carried by the rigid force absorber means, the flush valve automatically opening when the force absorber means impacts against the one end of the container.
