Abstract
In an inside-out flow filter, a transition pressure recovery member is provided at the inlet and has structured contoured guide surfaces guiding fluid flow therealong into the hollow interior of an annular filter element to minimize transition pressure loss from the inlet to the hollow interior. The transition pressure recovery member includes transition flow deceleration surfaces gradually decelerating flow of fluid into the hollow interior and minimizing pressure drop.
Claims29
An inside-out flow filter comprising an annular filter element having a hollow interior receiving fluid flowing axially thereinto through an inlet, said annular filter element comprising filter media for filtering said fluid, said fluid flowing from said hollow interior radially outwardly through filter media to an outer surface of said filter element, a transition pressure recovery member at said inlet and having structured contoured guide surfaces guiding fluid flow therealong into said hollow interior to minimize transition pressure loss from said inlet to said hollow interior.
