摘要： An engine for a portable engine-pump assembly is designed to operate on a safe fuel such as JP5 or DFM. The engine is started by a starting fuel such as propane which is supplied to the engine from a pressurized propane-containing cartridge. The propane starting system uses a puncturing device which has a built-in check valve function to isolate the propane system from moisture and contaminants in the air.

摘要： A system supplies compressed air and foam to produce a fire stream comprising an aerated foam. The system includes a fire pump, an air compressor, a mixer, and a controller for automatically maintaining a desired ratio of air and water delivered from the mixer to a fire stream delivery device. An electronic control unit is arranged to sense both the flow rate of the water delivered by the fire pump and the air flow rate delivered by the air compressor, and modulates an air pressure signal used to vary the flow of air to the inlet of the air compressor so as to hold the air flow rate and the water flow rate at the desired ratio.

The water flow sensor is configured to sense a water flow rate through the conduit. The air flow sensor is configured to sense an air flow rate through the air conduit. The system controller has a user adjustable ratio input. The system controller is configured to receive the sensed water flow rate, to receive the sensed air flow rate, to output a first control signal to the air flow control valve and to output a second control signal to the foam proportioning apparatus. The system controller automatically adjusts the first and second control signals to maintain a ratio of air flow to foam flow based upon the user adjustable ratio input.

摘要： An improved ball valve assembly is provided for use on firefighting equipment and other applications. The ball valve assembly includes an improved seal assembly which includes both a load bearing seal element and a soft elastomeric seal element. Both seal elements are held in place by a seat member which is accommodated in a recess provided on the inside surface of the seat housing or valve body. The load bearing seal member provides support for the ball element and serves to wipe or remove debris from the ball element before the ball element engages the soft elastomer seal. As a result, the load bearing seal member removes the stress normally imparted to soft elastomer seals utilized in ball valve assemblies. Further, a lubrication fitting and passageways are provided which enable lubricant to be communicated through the housing and through the seal assembly to the ball element. The ball valve assembly may also be connected in-line between conduits using circular clamps thereby enabling the ball valve to be rotated about the central axis of the conduit for versatility in installation and positioning. The lubricant fitting may be incorporated into an overall lubrication system for lubricating other ball valves on the firefighting equipment. The ball valve assembly may also be connected to a relief valve and disposed between a firefighting pump and behind a protective panel or housing thereby disposing both the ball valve and relief valve behind a protective housing as opposed to outside of the housing or the truck body in an exposed position.
