  • Patent number: 6915786
    Abstract: A fluid damper includes a hollow body portion, a first end and a second end. The hollow body portion has a corrugated or shaped outer surface and is filled with a compressible medium. The first and second ends of the damper contact the inner wall of the fluid-carrying line to stabilize the position of the damper within the fluid-carrying line to optimize dampening of the pressure pulsations in the fluid. The damper is formed by extruding or forming the hollow body portion into the desired shape, trimming the hollow body portion to the desired length, crimping and sealing the first and second ends by a heat staking process. The damper can be made from a material or materials that is impermeable and resistant to the fluid within the fluid system. The damper is integrally formed, thereby eliminating welding or manufacturing steps and reducing cost of manufacture.
