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.

Abstract:
The pressure regulator is designed for use with materials which are particularly subject to degradation such as metallic paints. The construction of the device allows for maintenance of laminar flow throughout the device. A circular disk is located a variable distance from the upper side of the pressure reducing chamber and leads to annular spaces around the stem of the disk, the clearance is being such as to maintain laminar flow.
