Abstract
A tool for creating grooves or cut-away portions in the inwardly extending corrugations of a flexible corrugated hose in order to eliminate noises created by movements of fluids, such as air, through the interior passage of the hose. The tool is a generally cylindrical member having outwardly extending fins extending at an angle to the longitudinal direction thereof. The tool is placed within the hose and relative movement in an axial or longitudinal direction causes the fins to act as cutting members and create the grooves or cut portions. The movement causes the fins to create an angled pattern of grooves relative to the axial direction.
Claims20
In a flexible elastomeric hose having a longitudinal axis and a fluid conveying passage and comprising corrugations extending inwardly into said passage;
- the improvement comprising means for reducing noises produced by movement of said fluid through said passage, said means comprising grooves formed by cutting away segments of at least some of the innermost portions of said inwardly extending corrugations.
The hose of claim 2 wherein said grooves are aligned in said corrugations at an angle to said longitudinal axis.
A tool for forming noise-reducing means in a flexible elastomeric hose having a fluid conveying passage and comprising corrugations extending inwardly into said passage, said tool comprising a generally cylindrical body adapted for movement within said passage, said body having means on its outer surface adapted for cutting into at least some of the innermost portions of said corrugations to form said noise-reducing means.
In a flexible elastomeric hose having a fluid conveying passage and comprising corrugations extending inwardly into said passage, a method of reducing noises produced by movement of said fluid through said passage comprising the steps of forming grooves in the innermost portions of at least some of said corrugations, said forming step comprising the cutting of segments in said at least some of said innermost portions.
