Abstract
An essentially closed hollow body of the float receives liquid in a lower portion for ballast and air in an upper portion for floatation with a vertical guide sleeve therethrough being offset at one side of the hollow interior slightly spaced inwardly of a part of the body sidewall. A liquid and air flow opening is formed through the body sidewall part horizontally centered relative to the guide sleeve so that flow paths are created segregated approximately one half around either side of the guide sleeve. By arcuately forming the body interior and the guide sleeve, not only are the flow paths smoothly arcuate, but the circuitous nature thereof muffles echoing sounds created within the hollow body from passing outwardly of the body through the flow opening.
Claims14
In a float of the type for use with ball cocks and the like in controlling the liquid level in tanks, the combination of:
- a hollow body having top, bottom and sidewalls;
- a float guide extending vertically through an interior of said body between said top and bottom walls horizontally interrupting and surrounded by said body interior, said guide being horizontally offset in said body and spaced a proportionately short distance from a part of said body sidewall;
- a fluid flow opening formed through said body sidewall part communicating into said body interior horizontally centered directly horizontally of said guide and of not greater horizontal width than said guide so that a flow path through said fluid flow opening is generally horizontally aligned with and is separated horizontally approximately one half to each side of said guide into and from a remainder of said body interior.
In a method of reducing noise emanating from a float for use with ball cocks and the like in controlling the liquid level in tanks, the steps of:
- positioning a vertical float guide horizontally interrupting a generally closed hollow interior of a float body;
- during said guide positioning, horizontally offsetting said guide in said body interior spaced a relatively short horizontal distance from an adjacent part of a body sidewall;
- during use of said float, flowing fluid into and from said body closed interior through said adjacent sidewall part in a fluid flow path not substantially greater in horizontal width than said guide and generally horizontally aligned with said guide resulting in said fluid flow being separated horizontally approximately one half to either side of said guide and then into a remainder of said body closed interior.
