ABSTRACT:
A flow restrictor to minimize noise and cavitation, or other adverse effects, in regulating the flow of a high pressure fluid. The restrictor defines a myriad of tortuous, dissimilar, intertwined, and commingled energy dissipating chambered flow paths edgewise through a stack of sheets of perforated stock material. Adjacent sheets have their perforations out of registration with one another, the inlet and outlet to the restrictor being edgewise through the stack through open-sided ones of the perforations of the several sheets of stock.
