Abstract: A spray nozzle assembly includes a body and a spray tip supported on the body. The spray tip includes a fluid inlet passage that terminates in an end wall. An annular discharge passage is arranged in the spray tip downstream of the end wall and the fluid inlet passage. The annular discharge passage defines a circular ridge in an external downstream surface of the spray tip. A plurality of discharge orifices through which fluid is discharged from the spray tip provided in the circular ridge. Each discharge orifice communicates with the annular discharge orifice and is formed in a respective notch in the circular ridge with each notch having at least one sidewall that defines a deflector surface for the respective discharge orifice.

Abstract: A spraying apparatus having an improved system for monitoring the flow of a spray nozzle or spray device and sensing malfunctions to the spray device is provided. The spraying apparatus includes sensors to monitor an input or instruction signal and a spray signal. The timing of the signals are analyzed to verify whether the spraying apparatus is opening and closing properly for each spray instruction signal.
