Fluid energy reducing device
First Claim
1. A fluid energy reducing device, comprising:
- a body having multiple first flow restrictors projecting outwardly away from a first body side, and multiple second flow restrictors projecting outwardly away from a second body side, the second flow restrictors directed oppositely with respect to the first flow restrictors, each of the first and second flow restrictors including;
a tapered body having an inlet defining an inlet area; and
an aperture created in the body having a flow area, the inlet area being greater than the flow area of the aperture to increase a flow velocity of a fluid between the inlet and the aperture.

Abstract
A fluid energy reducing device includes a body having multiple, oppositely directed flow restrictors extending away from opposite sides of the body. Each flow restrictor can have a geometric shape such as a pyramid, triangle, or a conical shape. Fluid such as a fuel traveling in a wave entering the flow restrictors accelerates as the flow area in a flow passage of the flow restrictors decreases. The work performed by accelerating the fluid flow through one or more apertures created in each flow restrictor reduces the energy of the wave, thereby reducing noise in the fluid tank having the fluid energy reducing device when the reduced size and velocity wave subsequently strikes tank structure or walls.

10. A fluid energy reducing device, comprising:
-
a body having multiple, oppositely directed flow restrictors projecting outwardly away from opposite sides of the body; each of the flow restrictors having a geometric shaped flow passage reducing in a flow area between an entrance to an exit aperture; wherein a fluid entering the flow restrictors accelerates as the flow area in the flow passage of the flow restrictors decreases thereby accelerating the fluid flow through the exit aperture created in each flow restrictor to reduce an energy of the fluid. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A fluid energy reducing device, comprising:
-
a polymeric body having multiple first flow restrictors projecting outwardly away from a first body side, and multiple second flow restrictors projecting outwardly away from a second body side, the second flow restrictors directed, oppositely with respect to the first flow restrictors, each of the first and second flow restrictors including; a flow restrictor body having an inlet defining an inlet area; and an aperture defining a flow area created in the flow restrictor body opposite to the inlet, such that the body defines a tapered internal passageway with the inlet area being greater than the flow area of the aperture; all proximate ones of the first and second flow restrictors being positioned directly in contact with each other such that no portion of the body where the first and second flow restrictors directly contact each other is oriented perpendicular to a longitudinal axis of an internal passageway of any of the flow restrictors with respect to a fluid directed toward the body from either the first body side or an oppositely facing second body side, wherein the body has a thickness and the first body side is on one side of the thickness and a second body side is opposite the thickness from the first body side. - View Dependent Claims (19, 20, 21)

-
a body; multiple flow restrictors projecting outwardly away from a first body side, each of the flow restrictors including; a taper shaped body having an inlet defining an inlet area; an aperture created in the taper shaped body having a flow area, the inlet area being greater than the flow area of the aperture. all proximate ones of the flow restrictors being positioned directly in contact with each other such that no portion of the body where the flow restrictors directly contact each other is oriented perpendicular to a longitudinal axis of an internal passageway of any of the flow restrictors with respect to a fluid directed toward the body from either the first body side or an oppositely facing second body side, wherein the first body side is between the bad and the first flow restrictors and the second body side is between the body and the second flow restrictors. - View Dependent Claims (23, 24)
