Abstract
An insert securable to the end of a hose is disclosed, the insert primarily intended to improve flow of a fluid emerging from the hose. The insert includes a generally cylindrical body portion, said body portion comprising an internal helical channel, the axis of said helical channel being offset from the insert axis, and conveniently parallel thereto.
Claims11
An apparatus, comprising:
- an insert (10) securable within a fluid pathway of a fluid delivering conduit, the insert comprising:
- a body (11, 21);
- a first fluid inlet disposed at a first end of the body;
- a body length axis (e.g., A-A, FIG. 3b) disposed normal to a plane passing through the first body end and extending, from a center of the first fluid inlet, between the plane and a second body end disposed opposite the first body end;
- a first fluid outlet disposed at the second body end;
- an internally disposed fluid-guiding channel (13, 23) extending as an uninterrupted path through the body between the first fluid inlet and the first fluid outlet, the channel being defined in-part, by a circumferentially disposed arcuate boundary line segment swept along a helical path with respect to the body length axis;
- and
- a flowpath, for fluid in the channel, defined by a centroid location of corresponding channel cross-sections along the helical path such that the flowpath is offset from the body length axis to guide fluid, that is flowing through the channel, toward a corresponding helical flow, the channel having a channel length extending along the flowpath;
- wherein:
- first coupling structure is associated with the body, the first coupling structure being operable to place the fluid inlet in fluid-tight communication with cooperating second coupling structure carried at a discharge end of the fluid delivering conduit;
- and
- a boundary edge of the channel is disposed at a radius from the body length axis by a distance larger than an outside radius of the fluid delivering conduit.

- and
- the body further comprises a flange (12) disposed to protrude radially at the first body end;
- and
- a frusto-conical section (41) connects the flange to the body, the frusto-conical section tapering from a larger diameter to a smaller diameter in the direction of the first fluid outlet.
