Abstract
Fluid flow control devices, systems, and methods may include a body extending along a longitudinal axis. The body has a fluid inlet at a first axial end of the body and a fluid outlet at a second axial end of the body. Channels may extend through an interior portion of the body between the fluid inlet at the first axial end and the fluid outlet at the second axial end. The channels collectively define fluid pathways through the body.
Claims20
A fluid flow control device, comprising:
- a single-piece substantially cylindrical body extending along a longitudinal axis, the single-piece substantially cylindrical body having a fluid inlet at a first axial end of the single-piece substantially cylindrical body and a fluid outlet at a second axial end of the single-piece substantially cylindrical body;
- and
- arcuate intersecting channels having a curved shape along a length of the channels, the channels extending through an interior portion of the single-piece substantially cylindrical body from the fluid inlet at the first axial end to the fluid outlet at the second axial end, the channels collectively defining fluid pathways through the single-piece substantially cylindrical body to reduce a pressure of a fluid traveling through the fluid pathways, each of the arcuate channels intersecting two or more other channels of the channels, wherein the channels extending between the fluid inlet at the first axial end and the fluid outlet at the second axial end are interior to, enclosed by, and entirely defined by the single-piece substantially cylindrical body;
- and
- wherein at least some of the channels extend longitudinally at a first substantially constant radial position from the longitudinal axis through the substantially cylindrical body and then vary from the first substantially constant radial position to extend toward the longitudinal axis as the channels approach the fluid outlet.

A fluid flow control device, comprising:
- a substantially cylindrical body extending along a longitudinal axis, the substantially cylindrical body having a fluid inlet at a first axial end of the substantially cylindrical body and a fluid outlet at a second axial end of the substantially cylindrical body;
- and
- channels extending through an interior portion of the substantially cylindrical body from the fluid inlet at the first axial end to the fluid outlet at the second axial end, the channels collectively spiral within the substantially cylindrical body to define curved intersecting fluid pathways through the substantially cylindrical body to reduce a pressure of a fluid traveling through the fluid pathways, each of the channels intersecting at least one other channel of the channels, wherein radial positions of at least some of the channels remain at a first substantially constant radial position along a length of the cylindrical body and change from the first substantially constant radial position as the channels approach the fluid outlet where the radial positions of the at least some of the channels vary from the first substantially constant radial position to extend radially inward and angle toward the longitudinal axis such that the at least some of the channels are positioned relatively closer to the longitudinal axis at the fluid outlet as compared to at the fluid inlet.
A fluid flow control device, comprising:
- a single-piece substantially cylindrical body extending along a longitudinal axis, the substantially cylindrical body having a fluid inlet at a first axial end of the substantially cylindrical body and a fluid outlet at a second axial end of the substantially cylindrical body;
- and
- curved intersecting channels extending through an interior portion of the substantially cylindrical body from the fluid inlet at the first axial end to the fluid outlet at the second axial end, the channels collectively defining fluid pathways through the substantially cylindrical body to reduce a pressure of a fluid traveling through the fluid pathways, each of the channels intersecting at least one other channel of the channels, wherein at least some of the channels extend longitudinally at a substantially constant radial position from the longitudinal axis and then vary from the substantially constant radial position as the channels approach the fluid outlet, and wherein the single-piece substantially cylindrical body comprises an axially extending cavity at the second axial end integrally defined within and extending into the single-piece substantially cylindrical body and being radially surrounded by an outer portion of the substantially cylindrical body, the axially extending cavity exhibiting a tapered shape having an enlarging cross-sectional area as the axially extending cavity opens at a terminal end of the substantially cylindrical body and wherein the fluid outlet is defined within the axially extending cavity.
A fluid flow control device, comprising:
- a substantially cylindrical body extending along a longitudinal axis, the substantially cylindrical body having a fluid inlet at a first axial end of the substantially cylindrical body and a fluid outlet at a second axial end of the substantially cylindrical body;
- and
- channels extending through an interior portion of the substantially cylindrical body from the fluid inlet at the first axial end to the fluid outlet at the second axial end, the channels collectively defining fluid pathways through the substantially cylindrical body to reduce a pressure of a fluid traveling through the fluid pathways, each of the channels intersecting at least one other channel of the channels, wherein the substantially cylindrical body includes a substantially cone-shaped protrusion to direct fluid flow at the fluid outlet, the substantially cone-shaped protrusion being surrounded by outlets of the fluid pathways.
