Abstract
An energy attenuation apparatus for a system conveying liquid under pressure, and a method for attenuating energy in such a system, are provided. The apparatus includes a hose or tubular casing having an inlet opening for receiving liquid from the system, and an outlet opening for returning the liquid to the system. An inlet conduit extends concentrically into the hose or tubular casing, with an annular space being formed between the inlet conduit and the tubular casing. At least one aperture for introducing liquid into the annular space from the inlet conduit is provided on a portion thereof that is disposed in the tubular casing.
Claims21
An energy attenuation apparatus for a system conveying a liquid under pressure, wherein said apparatus is disposed in a liquid conveying means of said system, said apparatus comprising:
- a tubular means that forms a single chamber having either an inlet opening or an outlet opening that is in fluid communication with said liquid conveying means for receiving liquid from or returning liquid to said system;
- and
- a conduit coupled at one end thereof in a fluid communicating manner with said liquid conveying means for receiving said liquid from or returning said liquid to said system, wherein said conduit is disposed essentially concentrically in said single chamber of said tubular means, wherein an annular space is formed between said conduit and said tubular means, wherein said conduit is provided with at least one aperture for allowing said liquid to exit said conduit, and wherein a free end of said conduit extends to the vicinity of said inlet or outlet opening of said single chamber of said tubular means but is not connected to said liquid conveying means at that location.
An energy attenuation apparatus for a system conveying a liquid under pressure, wherein said apparatus is disposed in a liquid conveying means of said system, said system comprising:
- a tubular means that forms a chamber having an inlet opening that is in fluid communication with said liquid conveying means for receiving said liquid from said system, and having an outlet opening that is in fluid communication with said liquid conveying means for returning said liquid to said system;
- a restrictor disposed in said chamber and dividing same into an inlet chamber and an outlet chamber;
- a first conduit disposed essentially concentrically in said inlet chamber and connected in a fluid communicating manner to said restrictor, wherein an annular space is formed between said conduit and said tubular means, wherein a free end of said first conduit extends to the vicinity of said inlet opening of said chamber of said tubular means but is not connected to said liquid conveying means, and wherein said first conduit is provided with at least one aperture for receiving said liquid;
- and
- a second conduit disposed essentially concentrically in said outlet chamber and connected in a fluid communicating manner to said restrictor, wherein an annular space is formed between said second conduit and said tubular means, wherein a free end of said second conduit extends to the vicinity of said outlet opening of said chamber of said tubular means but is not connected to said liquid conveying means, and wherein said second conduit is provided with at least one aperture for returning said liquid.
A connector for interconnecting a conduit in a fluid communicating manner with a liquid conveying means, said connector comprising:
- a first hollow cylindrical portion for insertion into and for a crimped connection to said liquid conveying means;
- and
- a second hollow barbed or ridged portion for insertion into and connection to said conduit.
