ABSTRACT:
A fluid filtering device comprises an inner member having an inner axial passageway for the fluid, and an outer housing radially spaced from the inner member to define therewith an outer axial passageway for the fluid, the inner member being formed with a radial passageway providing a communicating path between the two axial passageways for the fluid. A filter is disposed with the device upstream of the radial passageway in the path of the fluid flowing through the passageway, and a deflector is disposed within the axial passageway of the inner member on the upstream side of its radial passageway to deflect the fluid to flow through the radial passageway and through the filter. The deflector has a cylindrical wall disposed within the inner member and extending axially thereof, and a transverse wall extending transversely across the axial passageway of the inner member. A fluid flow control member is movable with respect to the cylindrical wall of the deflector and the radial passageway of the inner member to control the flow of the fluid through the radial passageway and through the filter.
