Abstract

An expanding tool comprising: an actuator comprising a cylindrical housing that defines an actuator housing cavity; a primary ram disposed within the actuator housing cavity, the primary ram defining an internal primary ram cavity; a secondary ram disposed within the internal primary ram cavity; a cam roller carrier coupled to a distal end of the secondary ram; a drive collar positioned within a distal end of the actuator housing cavity; a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar; a shuttle cam positioned between the roller clutch and a distal end of the primary ram; an expander cone coupled to the primary ram; and an expander head operably coupled to the drive collar.

First claim

We claim:

1. An actuator for use with a hydraulic tool comprising:
a housing defining a first cavity;
a primary ram disposed within the first cavity, the primary ram defining a second cavity;
a secondary ram disposed within the second cavity of the primary ram;
a drive collar positioned at a distal end of the first cavity; and
a shuttle cam at a first end of the primary ram, and
the shuttle cam moves along with the primary ram.

2. The actuator of claim 1 , wherein the shuttle cam is coupled to the primary ram such that the shuttle cam is suitable to move proximally along with the primary ram.

3. The actuator of claim 1 , wherein the shuttle cam is coupled to the primary ram such that the shuttle cam is suitable to move distally along with the primary ram.

4. The actuator of claim 1 , wherein the shuttle cam is suitable to rotate relative to the primary ram.

5. The actuator of claim 1 , wherein the shuttle cam is operatively coupled to the primary ram by way of a snap ring.

6. The actuator of claim 1 , further comprising a roller clutch disposed within an internal cavity defined by an inner surface of the drive collar.
