Abstract
A two component spray gun with low/high flow rates allows the operator to spray in confined areas at lower flow without having to change the mix module. The lower flow reduces undesirable 'spray back' and will also help reduce material waste. Pneumatic pistontravel, which determines on/off fluid flow, can be selected on the fly to either close the fluid portswhich stops fluid flow, partially open the fluid portswhich limits fluid flow, or to fully open the fluid portsto allow for maximum flow. Pneumatic pistontravel can be limited by means of a simple multi-position mechanical stop plunger. The stop barcan be connected to a knobor other operator input and turned or adjusted to the desired position.
