Hydraulic setting tool
Patent
·
OSTI ID:6490012
Apparatus for setting in a bore a well tool of the type having radially expandable anchor means and a mandrel-actuated slidable valve for permitting flow through the tool. Inner and outer sleeves are telescopically interengaged for suspension from a conduit string for lowering into a well bore. A shearable tension sleeve connects the tool to the lower end of the inner sleeve. A vertically shiftable mandrel having a longitudinal bore therethrough is received within the inner sleeve for engaging the well tool valve. A ball is received within a slot in the inner sleeve and is urged into a groove formed in the mandrel by a locking collar disposed about the inner sleeve. Annular pistons are provided between the inner and outer sleeves for moving the inner sleeve upwardly responsive to pressurization of the conduit string. Such upward movement shifts the mandrel downwardly with respect to the inner sleeve and shifts the locking collar to effect locking of the inner sleeve to the mandrel in its shifted position.
