  • Patent number: 4273270
    Abstract: An air powered dispenser connectable to a source of supply of pressurized air through a pressure reducing valve and a three-way valve. The air under pressure is supplied through a flexible air tube to a disposable syringe mounted on an adjustable guide fixed on a handle of a hand-held gun unit, in which is slidably mounted a trigger connected by a flexible tension cable unit to an actuator of the three-way valve. The hand-held gun unit is connected by the flexible tension cable unit and by the flexible air tube to the valves which may be located in a housing at a remote distance from the gun unit so as to eliminate the weight of the valves from the hand-held gun unit, while still providing finger control by the user of dispensing action.
