Abstract

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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 182 words
A flow device for a fluid stream to control the direction of said stream, said device comprising a conduit having an inlet for the fluid and at least one outlet for the fluid, said inlet and the or each outlet being separated from each other within said conduit by a gap coaxial with the axis of the conduit and defined by opposed offsettable inner edges of two mutually opposite flexibly mounted stream-deflecting members extending inwardly of said conduit in a direction transverse to the axis of said conduit; the arrangement being such that at least one of the stream-deflecting members is movable relative to the other by flexing that member in a direction parallel to the axis of said conduit whereby said inner edge of said one member is brought out of opposition with respect to the inner edge of the other member thereby to effect a corresponding change in the direction of the axis of said gap and consequently a corresponding change in the direction of the stream as it flows through said gap towards the outlet end of the conduit.
Claim 2
Dependent Claim 182 words
A flow device for a fluid stream to control the direction of said stream, said device comprising a conduit having an inlet for the fluid and at least one outlet for the fluid, said inlet and the or each outlet being separated from each other within said conduit by a gap coaxial with the axis of the conduit and defined by opposed offsettable inner edges of two mutually opposite flexibly mounted stream-deflecting members extending inwardly of said conduit in a direction transverse to the axis of said conduit; the arrangement being such that at least one of the stream-deflecting members is movable relative to the other by flexing that member in a direction parallel to the axis of said conduit whereby said inner edge of said one member is brought out of opposition with respect to the inner edge of the other member thereby to effect a corresponding change in the direction of the axis of said gap and consequently a corresponding change in the direction of the stream as it flows through said gap towards the outlet end of the conduit.
Claim 3
Dependent Claim 53 words
A flow device as claimed in claim 1, wherein said conduit is provided with two outlets and wherein the movement imparted to the stream-deflecting member serves to shift the stream flowing through said gap from one of said outlets to the other depending upon the direction in which said deflecting member is moved.
Claim 4
Dependent Claim 98 words
A flow device as claimed in claim 1 wherein movement of one of said stream-deflecting members relative to the other is effected by means of an actuating member therefor extending through a flexible wall portion of said conduit and which is connected to actuating means movable longitudinally of the axis of said conduit in one direction or the other. 4. A fluid flow control device as defined in claim 1 wherein said conduit is made of a flexible material and wherein the movement imparted to one of the stream-deflecting members relative to the other is effected by bending
Claim 5
Dependent Claim 67 words
said conduit longitudinally. 5. A fluid flow control device as defined in claim 1 wherein said means for imparting a movement to one of said stream-deflecting members relative to the other is constituted by a pair of selectively expandable chambers incorporated in a flexible wall portion of said conduit at opposite sides of said stream-deflecting member and which are selectively expanded by introduction of a pressurized fluid
Claim 6
Dependent Claim 35 words
medium. 6. A fluid flow control device as defined in claim 1 wherein said means for imparting a movement to one of said stream-deflecting members relative to the other is constituted by a temperature responsive
Claim 7
Dependent Claim 22 words
bimetallic member connected therewith. 7. A fluid control device as defined in claim 6 wherein said bimetallic member is located interiorly of
Claim 8
Dependent Claim 23 words
said conduit. 8. A fluid flow control device as defined in claim 6 wherein said bimetallic member is located exteriorly of said conduit.
