Abstract
A backflush conduit for an automatic back flushing filter having an inlet portion with a symmetrical converging bell-shaped cross-section, an outlet portion with a generally cylindrical shape, and a converging and reorienting transition portion connecting the inlet and outlet portions. Converging convex surfaces of the bell shaped opening smooth fluid inflow and prevent fulid separation. The transition portion interior contour redirects the fluid flow without inducing turbulence, resulting in more efficient backflushing to clean the entire filter element even at small element pore sizes.
