Abstract:
A one valve compressed air foam apparatus comprising:a source of compressed gas;a manifold having at least two ports wherein said source of compressed gas is placed in fluid communication with said manifold by way of the first of said ports;a valve, having an inlet port and an outlet port, wherein said inlet port is placed in fluid communication with said second port of said manifold, wherein said valve controls the flow of the compressed gas from said compressed gas source to said outlet port of said valve;a regulator place in fluid communication with said outlet port of said valve wherein flow of compressed gas is regulated;a compressed gas driven pump having a compressed gas inlet port, a fluid inlet port and a fluid outlet port wherein said compressed gas inlet port is placed in fluid communication with said regulator by a means for communication;a fluid storage means containing foam concentrate and water, said fluid storage means placed in fluid communication with said fluid inlet of said compressed gas driven pump;a mixing means having two inlet ports and one outlet port, wherein the first inlet port is placed in fluid communication with said fluid outlet port of said pump and said second inlet port is placed in fluid communication with said regulator by a means for communication, whereby said mixture of foam concentrate and water is mixed with said compressed gas forming the foam and communicating the foam to said outlet port of said mixing means; anda delivery hose, having an inlet end and a delivery end, wherein said inlet end is placed in fluid communication with said outlet port of said mixing means, whereby the foam is communicated through said delivery hose and allowed to discharge from said delivery end of said delivery hose.
