ABSTRACT:
A flow selector device makes use of an annular plate having a plurality of flow control orifices spaced about its perimeter. The plate is rotatably received within a housing that includes a first fluid conduit formed therein. The plate is selectively rotated to bring any one of the orifices therein into alignment with an open end of the first conduit by means of a removable cover on the housing. The conduit includes an annular seal about its open end and against which the orifice plate is pressed to seal the selected orifice within a fluid flow passage. A second fluid conduit is also provided and is connected to a clamp device mounting an open end of the conduit and a second annular seal. A clamp device is manually operable to securely clamp the plate between the seals, securing the plate in position with the selected orifice in line with and connecting the fluid flow conduits. The clamp device is also operable to release clamping pressure and thereby allow selective rotation of the orifice plate to bring a selected orifice into alignment with the conduit openings. The plate includes two sets of orifices arranged so that the plate may be inverted to bring either of the sets of orifices into operative positions where they may be selectively rotated into alignment with the conduit openings.
