Abstract
A safety valve includes a housing having a bore, a flow tube, and a valve closure member. The flow tube resides in the bore, is configured to move telescopically within the bore, and is adapted to shift the valve closure member between a closed position and an open position. The safety valve also includes an annular section between an inner surface of the housing and an outer surface of the flow tube, and means for preventing fluid flowing through the bore from entering the annular section.
