APPARATUS FOR HYDRAULICALLY ENERGIZING DOWN HOLE MECHANICAL SYSTEMS
First Claim
1. A pumping system for a downhole tool positionable in a wellbore penetrating a subterranean formation, comprising:
- an actuator having a body slidably positionable in a vessel, the body defining a first chamber and a second chamber in the vessel;
a fluid movement source having at least one port for selectively moving fluid in at least two directions; and
a passive flow distribution block adapted to selectively divert fluid from the fluid movement source to one of the first and second chambers whereby the body is selectively reciprocated.

Abstract
A pumping system for a downhole tool positionable in a wellbore penetrating a subterranean formation. The pumping system includes an actuator, a fluid movement source and a passive flow distribution block. The actuator has a body slidably positionable in a vessel. The body defines a first chamber and a second chamber in the vessel. The fluid movement source has at least one port for selectively moving fluid in at least two directions. The passive flow distribution block is adapted to selectively divert fluid from the fluid movement source to one of the first and second chambers whereby the body is selectively reciprocated.

11. A down hole tool positionable in a well bore having a wall and penetrating a subterranean formation, the formation having a fluid therein, the down hole tool comprising:
-
a housing; and
a pumping system, comprising;
an actuator having a body slidably positionable in a vessel, the body defining a first chamber and a second chamber in the vessel;
a fluid movement source having at least one port for selectively moving fluid in at least two directions; and
a passive flow distribution block adapted to selectively divert fluid from the fluid movement source to one of the first and second chambers whereby the body is selectively reciprocated. - View Dependent Claims (12, 13, 14, 15, 17, 18, 19)

20. A method for moving a body of an actuator of a downhole tool in at least two directions, the body slidably positionable in a vessel with the body defining a first chamber and a second chamber in the vessel, the downhole tool positionable in a well bore having a wall and penetrating a subterranean formation, the formation having a fluid therein, the method comprising the steps of:
-
actuating a fluid movement source to move fluid in a first direction through a passive flow distribution block and into the first chamber of the actuator to cause the body of the actuator to move in one direction; and
actuating the fluid movement source to move fluid in a second direction through the passive flow distribution block and into the second chamber of the actuator to cause the body of the actuator to move in another direction.
