ABSTRACT:
A well tool having reciprocating portions can be locked in a predetermined position by a latching mechanism which is responsive to externally applied pressure, as opposed to mere movement of the reciprocating elements to the predetermined position. The actuating pressure can be applied through the annulus or through a pipe string in which the tool is located.
