Estimating the term…
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 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 for causing a spray to be discharged from said spray head, said liquid supply system including two 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 (1) directing a pressurized fluid to one of said tanks while the other of said tanks is vented to atmosphere for directing liquid from said one tank to said spray head for discharge from said at least one spray nozzle and (2) directing a pressurized fluid to the other of said tanks while said one tank is vented to atmosphere for directing liquid from said other tank to said spray head for discharge from said at least one spray nozzle.
A liquid spraying system comprising:
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 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, directing liquid from said first tank to said spray head for discharging a liquid spray from said spray head, sensing the level of liquid in said first tank, and responsive to the liquid level in said first tank being lowered to a predetermined level automatically directing liquid from said second tank to said spray head and terminating the direction of liquid from said first tank to said spray head.
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 for causing a spray to be discharged from said spray head, 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, said tanks each having at least one liquid level sensor, and a control responsive to receiving signals from said liquid level sensors for successively directing liquid from said plurality of tanks to said spray head without disconnecting the fluid conduits of said tanks from said spray head.
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 for causing a spray to be discharged from said spray head, 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, 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, said liquid supply system having a first cycle of operation in which liquid is directed from one of said tanks to said spray head and a second cycle of operation responsive to the liquid in said one tank being lowered to a predetermined level for initiating a second cycle of operation in which liquid is directed from another of said tanks to said spray head.
