Abstract
A flow modifying device comprises an outer shell, a central tube within an interior space of the outer shell, and a plurality of helix vanes within the interior space. The central tube extends along at least a portion of a length of the outer shell. Each of the helix vanes extend along the outer shell and along the central tube. An outer edge portion of each of the helix vanes is attached to the outer shell and an inner edge portion of each of the helix vanes is located within a central passage of the central tube. In this manner, a first portion of each of the helix vanes extends between the outer shell and the central tube and a second portion of each of the helix vanes is located within the central passage of the central tube.
Claims20
A flow modifying device, comprising:
- an outer body;
- a plurality of vanes each extending in a helical manner within the outer body along at least a portion of a length of the outer body, wherein at least a portion of an outer edge portion of each of the vanes is attached to the outer body, wherein an inner edge portion of each of the vanes is located adjacent to a centerline longitudinal axis of the outer body, and wherein the inner edge portion of each of the vanes is spaced away from the inner edge portion of each other one of the vanes;
- and
- a plurality of elongated bodies each extending between respective adjacent ones of the vanes, wherein each of the adjacent vanes is attached to the elongated body extending therebetween, wherein the elongated bodies and the vanes jointly define a central passage extending along the centerline longitudinal axis of the outer body, and wherein each of the elongated bodies is located at a position between the outer and inner edge portions of each of the respective adjacent ones of the vanes.
A flow modifying device, comprising:
- an outer shell;
- a central tube within an interior space of the outer shell, wherein the central tube extends along at least a portion of a length of the outer shell;
- and
- a plurality of helix vanes within the interior space, wherein each of the helix vanes extend along at least a portion of a length of the outer shell and along at least a portion of a length of the central tube and wherein at least a portion of an outer edge portion of each of the helix vanes is attached to the outer shell and an inner edge portion of each of the helix vanes is located within a central passage of the central tube such that a first portion of each of the helix vanes extends between the outer shell and the central tube and a second portion of each of the helix vanes is located within the central passage of the central tube.
A flow modifying device, comprising:
- an outer shell that is conically shaped;
- a central tube within an interior space of the outer shell, wherein the central tube is cylindrically shaped, wherein the central tube extends along at portion of a length of the outer shell such that a length of the central tube is less than the length of the outer shell;
- and
- a plurality of vanes extending in a helical manner within the outer shell, wherein each of the vanes extend along at least a portion of a length of the outer shell and along at least a portion of a length of the central tube, wherein at least a portion of an outer edge portion of each of the vanes is integral with the outer shell and an inner edge portion of each of the vanes is located within a central passage of the central tube such that a first portion of each of the vanes extends between the outer shell and the central tube and a second portion of each of the vanes is located within the central passage of the central tube, wherein each of the vanes extends contiguously from the outer edge portion thereof to the inner edge portion thereof, and wherein adjacent ones of the vanes, the outer shell and the central tube jointly define a respective helical fluid flow passage.
