Abstract
A fluid resistance device being part of a fluid system and having high resistance, fluid energy absorbing passages within the plane surfaces of equally shaped circular plates which overlap each other in a prearranged pattern, each plate consisting of equally spaced circular segments, one half of which have a number of small openings while the other half define a large opening allowing for communication in planar and perpendicular direction between said small passages in both the adjacent segments.
Claims11
A fluid resistance device comprising:
- a vertical axis stack of coaxial, abutting horizontal circular plates,
- each plate being subdivided into first and second, wedge-shaped segments,
- at least one first segment per plate having a number of small, vertical, flow throttling holes therethrough,
- at least one second segment per plate having at least one large, vertical, flow passing opening therethrough, said large vertical opening have a cross-sectional area exceeding the combined cross-sectional areas of the small vertical holes of said at least one first segment,
- all stack plates being angularly displaced with respect to each other about the vertical stack axis so that in successive stack plates the large opening second segments overlap the small hole first segments, and
- the small holes of successive vertically overlying small hole first segments being angularly displaced with respect to each other about the vertical stack axis
- whereby are provided a number of tortuous fluid passageways extending through said stack in a vertical direction generally perpendicular to the horizontal plane surfaces of said plates.
