Compressed air foam discharging apparatus

Claim 2

A compressed air foam discharging apparatus for fighting fires and for containing hazardous material spills, the apparatus comprising: an engine having a first end; a drive shaft driven by the engine where at least a portion of the drive shaft extends outwardly from the engine's first end; a centrifugal fluid pump driven by and directly engaging the portion of the drive shaft extending outwardly from the engine's first end for pumping a first fluid through a first fluid channel; a rotary screw air compressor operatively associated with and driven by the portion of the drive shaft extending outwardly from the engine's first end for directing a second fluid through a second fluid channel; a connecting joining the first and second fluid channels allowing the first and second fluids to combine, where the connection includes an outlet; and a third fluid channel extending from the outlet of the connection.

Claim 3

The apparatus of claim 1 where the connection includes an air/water mixing tank.

Claim 4

The apparatus of claim 1 further comprising a foam concentrate reservoir operatively associated with the first fluid channel and an oil/air separator operatively associated with the second fluid channel.

Claim 5

The apparatus of claim 1 which further comprises an on/off valve connected to the third fluid channel.

Claim 6

A foam discharging apparatus for fighting fires and for containing hazardous material spills, the apparatus comprising: an air/water mixing tank operable to mix air and water admitted thereto; a hose having two ends with one end connected to the air/water mixing tank and the other end having a nozzle; an engine having a drive shaft extending from one end thereof; a centrifugal fluid pump having a drive shaft aligned with and directly engaging the drive shaft of the engine, the centrifugal fluid pump having an intake and an exhaust; a water reservoir; means connecting the water reservoir to the centrifugal fluid pump's intake; a first fluid output channeling means connecting the centrifugal fluid pump's exhaust to the mixing tank, the first fluid output channeling means including an aspirator and a foam concentrate reservoir connected to the aspirator; a rotary screw air compressor having a drive shaft; a belt extending around both the engine's drive shaft and the rotary screw air compressor's drive shaft; the rotary screw air compressor having an exhaust through which the compressed air flows; and second fluid output channeling means connecting the rotary screw air compressor's exhaust with the air/water mixing tank.

Claim 7

A foam discharging apparatus for fighting fires and for containing hazardous material spills, the apparatus comprising: an air/water mixing tank operable to mix air and water admitted thereto; a hose having two ends with one end connected to the air/water mixing tank and the other end having a nozzle; an engine having a drive shaft extending from one end thereof; a centrifugal fluid pump having a drive shaft aligned with and directly engaging the drive shaft of the engine, the centrifugal fluid pump having an intake and an exhaust; a water reservoir; means connecting the water reservoir to the centrifugal fluid pump's intake; a first fluid output channeling means connecting the centrifugal fluid pump's exhaust to the mixing tank, the first fluid output channeling means including an aspirator and a foam concentrate reservoir connected to the aspirator; a rotary screw air compressor having a drive shaft; a belt extending around both the engine's drive shaft and the rotary screw air compressor's drive shaft; the rotary screw air compressor having an exhaust through which the compressed air flows; and second fluid output channeling means connecting the rotary screw air compressor's exhaust with the air/water mixing tank.

Claim 8

A compressed air foam discharging apparatus for fighting fires and for containing hazardous material spills, the apparatus comprising: an engine having two ends; a drive shaft driven by the engine where at least a portion of the drive shaft extends outwardly from both ends of the engine; a centrifugal fluid pump directly engaging and driven by the portion of the drive shaft extending outwardly from one end of the engine for pumping a first fluid through a first fluid channel; a rotary screw air compressor driven by the portion of the drive shaft extending outwardly from the other end of the engine for directing a second fluid through a second fluid channel; a connection joining the first and second fluid channels allowing the first and second fluids to combine, where the connection includes an outlet; and a third fluid channel extending from the outlet of the connection.

Claim 9

A compressed air foam discharging apparatus for fighting fires and for containing hazardous material spills, the apparatus comprising: an engine having two ends; a drive shaft driven by the engine where at least a portion of the drive shaft extends outwardly from both ends of the engine; a centrifugal fluid pump directly engaging and driven by the portion of the drive shaft extending outwardly from one end of the engine for pumping a first fluid through a first fluid channel; a rotary screw air compressor driven by the portion of the drive shaft extending outwardly from the other end of the engine for directing a second fluid through a second fluid channel; a connection joining the first and second fluid channels allowing the first and second fluids to combine, where the connection includes an outlet; and a third fluid channel extending from the outlet of the connection.
