Abstract
A lamellate type low noise fluid resistance device comprising a stack of identical segmented ring-shaped plates having alternate sectional openings which, when circularly displaced with one another, form narrow horizontal fluid passages between the inner and outer diameters of said plates; said stack being bolted together with upper means to close the interior stack passage and lower flange means having a central opening and extending radially outward from the stack outer diameter.
Claims5
Lamellate fluid resistance device comprising:
- a. a stack of flat ring-shaped plates, having inner and outer diameters, each plate being subdivided into a number of even segments, each segment containing at least one perforation, extending along a circle located approximately midway between each plate's inner and outer diameter, one of said segments having a wedge-shaped opening of a width several times the plate thickness and extending radially between the plates' inner and outer diameters, all stack plates being angularly displaced with respect to each other by an angular distance of at least one of said segments so that the wedge-shaped opening of one plate can overlap the closed segment of the next plate, defining thereby a fluid passage between the inner and outer diameter of said stack of plates;
- b. means to support said stack of plates having a central opening in close proximity to the inside diameter of said plates, and having an external diameter extending beyond the outside diameter of said stack of plates;
- c. means to close off the upper terminating plate of said stack;
- d. a number of fastening devices interconnecting the means to support the stack of plates, each individual plate by means of said perforations, and said means to close off the upper terminating part.
