Circulating system for a conductor

An actuator combination for use with a fluid source including a fluid, the actuator combination comprising:

• a first core;
• a substantially tubular shaped conductor;
• and
• a circulating system that circulates the fluid, the circulating system including (i) a circulation housing having a tubular shaped, housing cavity which receives the conductor and provides a fluid passageway between the circulation housing and the conductor, and (ii) a fluid inlet into the fluid passageway, the fluid inlet being in fluid communication with the fluid source so that fluid from the fluid source can be supplied to the fluid passageway.

A method for cooling a substantially tubular shaped conductor, the method comprising the steps of:

• providing a circulation housing including a tubular shaped housing cavity that receives the conductor and defines a fluid passageway between the circulation housing and the conductor;
• positioning the conductor in the housing cavity;
• and
• directing a fluid through the fluid passageway to cool the conductor.

A method for making an actuator combination adapted for use with a fluid source including a fluid, the method comprising the steps of:

• providing a first core;
• providing a substantially tubular shaped conductor that encircles a portion of the first core;
• and
• providing a circulating system including (i) a circulation housing that encircles the conductor and provides a fluid passageway between the circulation housing and the conductor, and (ii) a fluid inlet into the fluid passageway in fluid communication with the fluid source so that the fluid from the fluid source can be supplied to the fluid passageway.
