Patent ID: 7316501

Claim:
An apparatus for the mixing of two or more dissimilar fluids together comprising a housing having a chamber and first and second fluid inlets and a fluid outlet in fluid communication with said chamber, one of said dissimilar fluids entering said chamber at one of said inlets and the other of said dissimilar fluid entering said chamber at the other one of said inlets, said first and second fluid inlets and said fluid outlet each opening exteriorly of said housing; a rotatable unit disposed centrally in said chamber and mounted for rotation within said chamber about an axis of rotation, said rotatable unit and said chamber defining an inlet region having first and second sub-regions, an exhaust region and a fluid mixing region, wherein said rotatable unit is provided with at least one circumferential row of bottom-ended holes formed on a face thereof, said fluid mixing region providing a unidirectional pathway for said dissimilar fluids upon entering said inlet region to reach said fluid outlet via said exhaust region, and said fluid outlet being nearer a distal end of said rotatable unit than said at least one circumferential row of bottom-ended holes; said rotatable unit further comprising a port formed on a face thereof, said port communicating with internally disposed fluid passageways disposed in said rotatable unit, said fluid passageways comprising a longitudinal passageway and a radial passageway, said radial passageway communicating with said second sub-region to supply one of said dissimilar fluids to said fluid mixing region, the supply of the other of said dissimilar fluids to said fluid mixing region being via said first sub-region, said first sub-region being nearer the proximal end of said rotatable unit than said second sub-region, said port being in fluid communication with one of said first and second fluid inlets and the other of said first and second fluid inlets being in fluid communication with said first sub-region, said radial passageway being spaced from the proximal end of said rotatable unit by said at least one circumferential row of bottom-ended holes and said at least one circumferential row of bottom-ended holes being intermediate said first and second sub-regions.
