Abstract
A valve control mechanism for a paint spraying system provides for pressure relief prior to turn-off of the compressor. A pair of interlocking knobs, a pressure control knob and an off-prime-spray knob, are mechanically interlocked so that the compressor can only be turned on and off in a low pressure condition. When spraying has been completed, it is necessary to first operate the off-prime-spray knob to the prime position at which a cam structure opens the off-prime-spray valve for an immediate pressure relief prior to turn off of the pump.
