Abstract
A valve assembly for controlling fluid flow to a tube connected to the assembly by shifting of a sleeve mounted on the assembly. When the sleeve is shifted into a shutoff position, a fluid path through the assembly is completely occluded by a closure element in the sleeve. As the sleeve is rotated away from its shutoff position, the fluid path is gradually opened.
Claims16
A fluid flow controlling valve assembly comprising:
- a body including a first conduit having an aperture opening to a surface of said body, and a second conduit having an aperture opening to a surface of said body;
- and
- a sleeve mounted on the body forming a chamber therebetween defining a fluid flow passage between said first conduit and said second conduit, the sleeve being rotatable around the body and operable to change the dimension of the fluid flow passage to control fluid flow between said first and second conduits, said sleeve including a variable cross-section closure element therein having a helical configuration extending about a major portion of the closure element operable upon rotation of the sleeve to a first position to open said fluid flow passage and upon rotation of the sleeve to a second position to restrict such fluid flow passage.
A valve assembly comprising:
- a body having a first conduit defined therein having an outlet opening in a selected region of the surface of the body and a second conduit having an inlet opening at a second selected region of the surface of the body;
- a sleeve mounted in sealing engagement and for rotation on said body defining a chamber into which both said inlet and outlet openings extend, said chamber providing a fluid flow passage between said inlet and outlet openings, and an adjustable fluid controller mounted within said chamber shiftable between selected positions to vary the fluid flow passage between the outlet and the inlet openings of said conduits, said controller including a closure element having a substantially helical configuration extending about a major portion of the closure element operable on rotation of the sleeve to selectably occlude one of the conduit openings at the surface of the body to selectively open and close the opening of the conduit on said body.
A valve assembly connectable to a fluid source comprising
- an elongate body having a first end and a second end;
- a first fluid flow passageway in said body having an inlet and an outlet;
- a second fluid flow passageway in said body having an inlet and an outlet, the inlet of the second passageway being positioned adjacent to the outlet of the first passageway, and
- valve means mounted on the body and configured for defining a fluid flow path from the outlet of the first passageway to the inlet of the second passageway and for regulating the flow of fluid therebetween, said valve means comprising a sleeve mounted in sealing engagement on and rotatable about said body, and having an internal bore with a helical groove extending about a major portion of the sleeve configured and positioned on said sleeve to gradually occlude the outlet of the first passageway as the sleeve is rotated in one direction.

A fluid flow controlling valve assembly comprising:
- a body including a first conduit having an aperture opening to a surface of said body, and a second conduit having an aperture opening to a surface of said body;
- and
- a sleeve mounted on the body forming a chamber therebetween defining a fluid flow passage between said first conduit and said second conduit, and a closure element in said sleeve, the sleeve and closure element being movable relative to the body and operable to change the dimension of the fluid flow passage to control fluid flow between said first and second conduits, said body and sleeve having mating helical threaded sections whereby said sleeve is threadably connected to the body for rotation thereabout and upon rotation about the body the sleeve and its associated closure element are shiftable longitudinally of the body between longitudinally spaced first and second positions, wherein the closure element is positioned to occlude one of said conduits when the sleeve is moved to said second position and is positioned to open said one conduit when the sleeve is moved to said first position.
A fluid flow controlling valve assembly comprising:
- a body including a first conduit having an aperture opening to a surface of said body;
- and a second conduit having an aperture opening to a surface of said body;
- a sleeve mounted on the body with an annular opening therebetween forming a chamber defining a fluid flow passage between said first conduit and said second conduit, and a closure element in said sleeve comprising an annular element sealingly interposed between the sleeve and body in said chamber, the sleeve and closure element being movable relative to the body and operable to change the dimension of the fluid flow passage to control fluid flow between said first and second conduits, said sleeve being threadably connected to the body for rotation thereabout and upon rotation about the body the sleeve and its associated closure element being shiftable longitudinally of the body between first and second positions, wherein the closure element is positioned to occlude one of said conduits when the sleeve is moved to said second position and is positioned to open said one conduit when the sleeve is moved to said first position;
- and
- a biasing element operatively urging said closure element toward one of its positions and said sleeve is operable to move the closure element against the urging of said element toward its other position upon rotation of the sleeve.
