  • Single-pressure actuated control system for compressed air spraying of water
    Patent number: 4591095
    Abstract: In a single-pressure actuated control system for compressed air spraying of water, a rising pressure of an air supply line actuates an air valve to supply the air to the nozzle and to a tank, and a water valve is subsequently actuated by the pressure from the air valve to supply water to the nozzle. As the air supply pressure falls, first the air valve and then the water valve closes, and the air stored in the tank drains water downstream of the water valve to prevent dripping from the nozzle.
