ABSTRACT:
In an orifice and nozzle for the passage of fluid which may contain solid particulates as contaminants, the orifice and nozzle includes an opening which is rectangular in a cross-sectional plane perpendicular to the axis of the fluid flow. The rectangular opening has a ratio of minimum width to minimum depth, or vice versa, of less than approximately 1.5, and preferably 1.0, and a ratio of the length of the opening to the lesser of minimum width and minimum depth of the opening of less than approximately 2.0, and preferably 1.0. The rectangular cross section together with these ratios prevents plugging by the solid contaminants.
