Abstract
Abstract A dampener is disclosed for use in a pipeline, to reduce noise, vibration and peak pressures. A housing receives intake and outlet manifold structures which impart an orbital spin flow pattern to the liquid causing it to move in a circle about the axis of the major flow pattern. The manifolds as disclosed are somewhat flat members defining radially-extending peripheral shoulders which are ported to communicate with radially-extending passages through which fluid is communicated into and out of the orbital flow pattern. As disclosed herein, the housing is spherical with axially-aligned inlet and outlet ducts, and nozzles are provided in the ports of the inlet manifold.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
172 words
A liquid pUlsation dampener, as for use in a liquid stream, comprising: a housing means defining an internal cavity as a figure of rotation about a central axis; a first manifold member affixed in said housing, adapted to receive said liquid stream, said first manifold member defining a central intake duct connected to a plurality of first passages extending radially to the axis of said figure of rotation and terminating at first sections extending substantially tangentially to said figure of rotation to communicate with said internal cavity; and a second manifold member affixed in said housing in opposed relationship to said first manifold member, said second manifold member defining a central exhaust duct connected to a plurality of second passage extending radially to the axis of said figure of rotation and terminating at second sections extending substantially tangentially to said figure of rotation to communicate with said internal cavity, said exhaust duct extending out of said housing substantially aligned with said central intake duct at the axis of said figure of rotation.
Claim 2
Dependent Claim
172 words
A liquid pUlsation dampener, as for use in a liquid stream, comprising: a housing means defining an internal cavity as a figure of rotation about a central axis; a first manifold member affixed in said housing, adapted to receive said liquid stream, said first manifold member defining a central intake duct connected to a plurality of first passages extending radially to the axis of said figure of rotation and terminating at first sections extending substantially tangentially to said figure of rotation to communicate with said internal cavity; and a second manifold member affixed in said housing in opposed relationship to said first manifold member, said second manifold member defining a central exhaust duct connected to a plurality of second passage extending radially to the axis of said figure of rotation and terminating at second sections extending substantially tangentially to said figure of rotation to communicate with said internal cavity, said exhaust duct extending out of said housing substantially aligned with said central intake duct at the axis of said figure of rotation.
Claim 3
Dependent Claim
19 words
A liquid pulsation dampener according to claim 1 further including nozzle means affixed in said plurality of first sections.
Claim 4
Dependent Claim
35 words
A liquid pulsation damper according to claim 1, wherein the total cross-sectional area of said radial first passages defined in said first manifold member is smaller than the cross-sectional area defined in said intake duct.
Claim 5
Dependent Claim
31 words
A liquid pulsation damper according to claim 1, wherein said manifolds each comprise a somewhat flat structure, defining a plurality of radially extending shoulders wherein ports are defined into said sections.
Claim 6
Dependent Claim
15 words
A liquid pulsation damper according to claim 4, wherein said housing means comprises a sphere.
