ABSTRACT:
In accordance with an illustrative embodiment of the present invention, a one-way clutch mechanism is incorporated between the mandrel and housing of a rotary-operated pump apparatus that is used to inflate the packers of a drill stem testing system. The mandrel can be freely rotated to the right to operate the pump, however left-hand rotation causes the clutch mechanism to engage and the housing to be rotated with the mandrel to the left to disconnect a safety joint located in the tool string between the pump apparatus and the packers.
