ABSTRACT:
A flow device for interaction with a fluid stream to control its direction comprises a conduit system which includes a cavity in communication with an inlet for the stream and at least one outlet for the stream. Controllable flexible means co-operative with the cavity are provided for interaction with the stream and function to deflect the stream in one direction or the other from its entering direction as it leaves the cavity. The fluid stream can be selectively directed into one or the other of two separate outlets, or a single outlet can be combined with a vortex arrangement so as to enable one to select the direction of rotation of the stream about the axis of the vortex. In one embodiment of the invention, the controllable flexible means by means of which the stream is made to change its direction or flow is constituted by a flexible diaphragm situated at the branching point of Y-shaped outlets which shifts the fluid flow from one branch to another; in another embodiment the stem of a Y-shaped arrangement is bent in one direction or the other to effect a shift in the fluid flow from one branch outlet of the Y to the other; in another embodiment, a deflectable vane is situated in the branching point of the Y-shaped arrangement; in still another embodiment, the conduit is provided with an inlet and an outlet separated by a gap established by the inner ends of two mutually opposite fluid stream-deflectable members together with means for imparting a turning movement to at least one of the deflectable members in one direction relative to the other to effect a corresponding change in direction of the fluid flow at the outlet; and according to still another embodiment, the conduit system takes the form of a vortex fluidister having a cylindrical primary flow-through passage and a secondary inlet including a rigid tube entering through the wall of the primary flow-through passage but which can be brought to varying angular positions from an initial position normal to the primary flow-through passage.
