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

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.
