Zusammenfassung:	A screen assembly. The screen assembly may include a base pipe having an axial bore formed therethrough. An axial rod may be positioned radially-outward from the base pipe. A screen may be positioned radially-outward from the axial rod. A housing may be positioned radially-outward from the base pipe and axially adjacent to the axial rod, the screen, or both, and a first annulus may be formed between the housing and the base pipe. A first opening may be formed through the base pipe and radially-inward from the housing. A second opening may be formed through the base pipe and radially-inward from the housing, and the second opening may be axially offset from the first opening. A valve may be disposed within the first annulus and positioned axially between the first and second openings.
