Abstract
A flow control device is described comprising a body including a first flow control member 24a and a second flow control member 24b, each of which is provided with apertures or recesses 30, 36, 38, the apertures or recesses 30 of the first flow control member 24a overlapping the openings or recesses 36, 38 of the second flow control member 24b to define a flow path extending between a first surface 26 of the body and a second surface 28 of the body, wherein the shapes and/or sizes of at least some of the apertures or recesses 30, 36, 38 of at least one of the flow control members 24a, 24b are adapted to promote tangential or transverse fluid flow within the body.
Claims20
A flow control device comprising a body including a first flow control member and a second flow control member, each of which is provided with apertures or recesses, the apertures or recesses of the first flow control member partially overlapping the apertures or recesses of the second flow control member in a radial extension to define a flow path extending between a first surface of the body and a second surface of the body, at least a portion of the first flow control member or the second flow control member defining a tongue projecting into the respective aperture or recess, the tongue being located relative to the aperture or recess in an off-center location, whereby at least some of the apertures or recesses of at least one of the flow control members are adapted to promote, relative to a radial extension between the first surface and the second surface, non-radial fluid flow within and through the apertures or recesses, and thereby within the body.
A flow control device comprising a body including a first flow control member and a second flow control member, each of which is provided with apertures or recesses, the apertures or recesses of the first flow control member partially overlapping the apertures or recesses of the second flow control member in a radial extension to define a flow path extending between a first surface of the body and a second surface of the body, and further overlapping in a non-radial fluid flow dimension, wherein shapes and/or sizes of at least some of the overlapping apertures or recesses of the first and second control members present a relatively larger restriction to fluid flow and relatively smaller restriction to fluid flow and/or comprise flow-directing regions, within the aperture or recess, whereby at least some of the apertures or recesses of at least one of the flow control members are adapted to promote, relative to a radial extension between the first surface and the second surface, non-radial fluid flow within and through the apertures or recesses, and thereby within the body, wherein the apertures or recesses provided within the first flow control member are of a substantially uniform radial extent, and the apertures or recesses provided in the second flow control member are of a varying radial extent.
A flow control device comprising a body including a first flow control member and a second flow control member, each of which is provided with apertures or recesses, at least some of the apertures or recesses of the first flow control member partially overlapping apertures or recesses of the second flow control member in a radial extension to define a flow path extending between a first surface of the body and a second surface of the body, wherein at least one of the first flow control member and the second flow control member has at least one tongue which projects into at least one of the overlapping apertures or recesses of the first flow control member or the second flow control member, the at least one tongue segmenting the aperture or recess into a first segment and a second segment, the first segment and second segment in fluid communication with each other for at least some non-radial fluid flow across the first and second segments, the arrangement of the control members and the apertures or recesses being such that (a) a radially inner part of each aperture or recess partially overlaps a relatively small aperture or recess and partially overlaps a relatively large aperture or recess and (b) a radially outer part of each aperture partially overlaps with a relatively small aperture or recess and partially overlaps a relatively large aperture or recess, whereby each of the first segment and the second segment of each aperture or recess registers with both a relatively small aperture or recess and a relatively large aperture or recess, thereby providing differently sized restrictions to fluid flow in the first segment and the second segment of the aperture or recess.
