A fluid manifold includes an inlet comprising an opening into an interior of the fluid manifold, an outlet end that is positioned opposite the inlet and that is in fluid communication with the inlet, a shroud extending between the inlet and the outlet end and surrounding a flow path of the fluid manifold, and a first flow distributor positioned within the interior of the fluid manifold. The first flow distributor includes a hollow body including a first surface at a downstream side of the first flow distributor and a second surface at an upstream side of the first flow distributor, a central cavity defined by the second surface of the hollow body, and openings extending from the first surface to the second surface such that a fluid can pass from the central cavity through the openings. The first flow distributor and the fluid manifold are integrally formed.

A fluidic device comprises a first channel conduit, a valve apparatus, and an additional element adjacent to the first channel conduit. The first channel conduit transports fluid from a first fluid entrance to a fluid exit. In one embodiment, the additional element is a pump chamber that receives fluid from a second fluid entrance and pumps fluid into the first channel conduit in accordance with fluid pressure. Alternatively, the additional elements include a second channel conduit and a neck of the first channel conduit. The first channel conduit and the second channel conduit share a common wall. Fluid pressure in the first channel conduit controls a valve apparatus. The value apparatus controls a rate of fluid flow in the first channel conduit by deforming the common wall to change a cross-sectional area of the neck, which changes a rate of fluid flow in the second channel conduit.

Embodiments of apparatus for controlling the movement of matter, including but not limited to one-way fluid valves, are disclosed. The apparatus may include a transition nozzle, a funnel nozzle, and a reverse flow blocker arranged in series in a case. A counter-flow area may be disposed about the funnel nozzle. The apparatus may permit matter to flow in a first direction, and discourage or prevent flow in a direction reverse to the first direction. Control over the flow of matter may also enable the matter to be harvested, sorted, separated or combined with injected matter.

A flat reverse vortex ring is sized and shaped to either attach to or be formed as part of a distal end of a sleeve bearing or seal. The ring has a series of evenly spaced radial channels that extend from an inner diameter to an outer diameter of the ring. The channels have a depth. The ring has an upper surface with an alternating series of planar surfaces and openings located at an upper end of the channels. The ring may have an interior diameter equal to an interior diameter of the sleeve bearing or seal. The ring may have an exterior diameter equal to an exterior diameter the sleeve bearing or seal. The channels may be semi-cylindrical. The channels have a diameter and the depth is a predetermined portion of the diameter. The channels may be rectangular in cross-section with a height-to-width ratio of between 0.5 and 1.5.

There is disclosed a unidirectional liquid transport system. The system, or a liquid diode, has an array of elongate units. Each unit is defined by a surrounding fencing, and includes a region generally resembling a U-shaped micro-scale island with a proximal end on one side having an opening and a distal end on the opposite side thereof. A channel is defined between a lateral side of the island and an adjacent fencing thereof, and the channel is divergent from the proximal end towards the distal location on the opposite side thereof. The island includes a reentrant member configured to, upon contact with droplets of a liquid to be transported, initially arrest flow of the liquid and produce a pinning acting to allow building up of excess surface energy, and subsequently cause coalescence of the liquid thus converting the surface energy to kinetic energy for movement of the liquid; and surfaces of the units are fabricated on silicon wafer.
