Abstract:
Apparatus for damping a pulsation of a fluid conveyed through a fluid flow system comprising a housing defining a cavity, said housing including a flexible element adjacent said cavity, a first tubular element positioned in said cavity for receiving fluid, said first tubular element having an outlet end within said cavity, and a second tubular element positioned in said cavity for directing fluid out of said cavity, said second tubular element having an inlet end within said cavity positioned along side of said first tubular element, each of said tubular elements having a length less than the length of said cavity, the sum of the lengths of said tubular elements being greater than the length of the cavity, said tubular elements overlapping one another such that fluid flowing out of said outlet end of said first tubular element must flow in a generally reverse direction from the direction of flow within said first tubular element in order to reach said inlet end of said second tubular element.
