A liquid spraying system having a spray head and a recirculating liquid supply system for directing pressurized supply liquid to the spray head with a portion of the liquid being directed from the spray head as a discharging spray and a portion of the supply liquid exiting the spray head as a return liquid. The liquid supply system includes two separate selectively pressurizable liquid containable tanks each having a respective fluid conduit coupled to the spray head. The liquid supply system has (1) a first cycle of operation in which the first tank is pressurized and the second tank is depressurized so that pressurized liquid is supplied from the first tank to the spray head and return liquid is directed to the second tank, and (2) a second cycle of operation in which the second tank is pressurized and the first tank depressurized so that liquid is supplied to the spray head from the second tank and return liquid is directed to the first tank.
A liquid spraying system comprising a spray head having at least one spray nozzle for discharging a liquid spray, a liquid supply system for directing pressurized supply liquid to the spray head with a portion of the supply liquid being directed from said spray head as a discharging spray and a portion of the supply liquid exiting the spray head as a return liquid,
A liquid spraying system comprising a spray head having at least one spray nozzle for discharging a liquid spray, a liquid supply system for directing pressurized supply liquid to the spray head with a portion of the supply liquid being directed from said spray head as a discharging spray and a portion of the supply liquid exiting the spray head as a return liquid, said liquid supply system including a plurality of selectively pressurizable liquid containable tanks, said tanks each having a respective fluid conduit coupled to said spray head, and said liquid supply system being operable for successively directing pressurized liquid to said spray head from said plurality of tanks without disconnecting the fluid conduits of said tanks from said spray head.
A method of supplying liquid to a spray head having at least one spray nozzle comprising the steps of providing first and second pressurizable liquid containable tanks, filling the first tank with supply liquid to a level above a predetermined low level, pressurizing said first tank and depressurizing said second tank so that pressurized liquid is supplied from said first tank to said spray head with a portion of the supply liquid being directed from said spray head nozzle as a discharging spray and a portion of said supply liquid exiting said spray head as a return liquid, and directing said return liquid to said second tank while said second tank is depressurized.
A method of supplying liquid to a spray head having at least one spray nozzle comprising the steps of providing a first pressurizable liquid containable tank having a first conduit coupled to said spray head, providing a second pressurizable liquid containable tank having a second conduit coupled to said spray head, filling said first tank with supply liquid to a level above a predetermined low level, pressurizing said first tank and depressurizing the second tank so that pressurized liquid is supplied from said first tank through said first conduit to said spray head with a portion of the supply liquid being directed from said spray head nozzle as a discharging spray and a portion of said supply liquid exiting said spray head as a return liquid, and directing said return liquid through said second conduit to said second tank while said second tank is depressurized.
