  • Foam additive supply system for rescue and fire fighting vehicles
    Patent number: 6725940
    Abstract: A system for supplying a pre-determined ratio of liquid foam concentrate and water to a mixing device immediately upstream from a fire fighting nozzle. The system is electronically balanced by measuring pressure from a plurality of pressure signal sensors and transmitting said pressure signals to a controller unit. A foam additive pump is powered by a fixed displacement piston motor which in turn is electronically modulated independently of the level of operation of the water pump by a control system that is responsive both to the water pressure developed by the water pump and to the foam liquid concentrate pressure developed by the additive pump.
