Abstract: A flow selector device 10 makes use of a cover member 59 rotatably mounted to a base member 21. The cover member 59 includes a plurality of exposed, outwardly oriented flow control nozzles 14 spaced about its external parametrial wall 62. The cover 59 spans the base 21 which includes a fluid conduit 32 formed therein for connection to a source of fluid 11. The cover 59 is selectively rotated to bring any one of the nozzles 14 therein into alignment with an open end 34 of the conduit. A clamp device 43 and seal 48 is manually operable to securely clamp the seal 48 against a selected nozzle 14, such that fluid will flow from the source 11 through the conduit 32 and out through the selected nozzle 14 without leakage about the seal 48. The clamp device 43 is also operable to release clamping pressure and thereby allow selective rotation of the cover 59 to bring another selected nozzle 14 into alignment with the conduit 32.

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.
