Abstract:
1. A valve apparatus comprising a cylindrical casing; a shaft arranged symmetrically in said casing; a member fixedly attached to said shaft and in close fit with said cylindrical casing, thereby defining separated chambers within the casing; at least one outlet fixedly arranged along the circumference of said casing; and a plurality of axially arranged inlets, each of which being constantly in fluid communication with a respective one of said separated chambers, wherein the separated chambers and thereby the axially arranged inlets are alternately in fluid connection with a circumferential reference point of said at least one outlet in response to rotation of said shaft and said member with respect to said casing, wherein said at least one outlet has a fluid path length that varies along the circumference of said casing depending on the rotational speed of said shaft and said member such that the interfaces between fluids originating from different ones of said axially arranged inlets will be essentially vertical to the flow direction of the fluids downstream of said at least one outlet; and wherein said valve apparatus comprises a plurality of outlets fixedly arranged along the circumference of said casing; and the separated chambers and thereby the axially arranged outlets are alternately in fluid connection with each of the outlets fixedly arranged along the circumference of said casing in response to the rotation of said shaft and said member with respect to said casing.
