Abstract:
An improved laminar nozzle assembly comprising:means for causing fluid to enter the nozzle assembly; a diffuser located within said assembly; said diffuser comprising a porous filter formed into a hollow hemisphere having a generally convex surface and a generally concave surface; said generally concave having a center spaced from said generally convex surface; an exit orifice spaced from said generally concave surface and located generally at said center, whereby as said fluid flows through said hollow hemispherical diffuser it has its Reynold's Number significantly reduced, and any turbulances on said convex surface tend to be converted to a very great number of micro-turbulances which tend to be self canceling and substantially all water flowing from the diffuser to the exit orifice has substantially the same distance to travel from substantially all directions, the fluid exiting said orifice is highly laminar.
