Abstract
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.
