Abstract
A back pressure regulator is provided which utilizes laminar flow at all times to minimize degradation of paint which might have metallic particles passing there through. The pressure drop across the regulator is accomplished by utilizing this viscous friction rather than velocity change through an orifice as is common with a conventional pressure regulator.
