ABSTRACT:
A dual pressure regulator device for a spray gun is supplied with an input fluid under pressure and outputs a first regulated pneumatic pressure to a pressurized tank, and a second regulated pneumatic pressure to the spray gun. The dual pressure regulator device has a unitary body having a fluid passageway extending from an inlet port at a first end of the body, to which inlet port the input fluid is supplied, to a first valve chamber in which a first regulator valve is installed, and to a second valve chamber in which a second regulator valve is installed. The pressure in the nozzle device's main pressure internal line and the head pressure within the tank are maintained within specified tolerances, independent of pressure fluctuations in the main supply line to the nozzle device. The body has an inclined body wall portion that is conformal with the handle, such that the valve assemblies are physically accommodated and accessible in a space directly beneath the handle, adjacent to the tank.
