1. A peristaltic pump assembly for moving a working fluid comprising:
- an expandable fluid that changes in volume due to the presence of at least one of a magnetic field and an electric field;
a flexible member interposed between the working fluid and the expandable fluid; and
a field generator operable to cause the expandable fluid to change in volume by applying at least one of a magnetic field and an electric field to the expandable fluid, which, in turn, moves the flexible member to increase the pressure of the working fluid to thereby move the working fluid.

Abstract
A peristaltic pump assembly for moving a working fluid. The pump assembly includes an expandable fluid that changes in volume due to the presence of a magnetic and/or electric field. The pump assembly also includes a flexible member interposed between the working fluid and the expandable fluid. The pump assembly further includes a field generator operable to cause the expandable fluid to change in volume by applying the magnetic and/or electric field to the expandable fluid. This, in turn, moves the flexible member to increase the pressure of the working fluid to thereby move the working fluid.

9. A vehicle comprising:
-
a first component;
a second component; and
at least one peristaltic pump assembly interconnecting the first component and the second component, the pump assembly operable for moving a working fluid between the first component and the second component, the at least one pump assembly comprising;
an expandable fluid that changes in volume due to the presence of at least one of a magnetic field and an electric field;
a flexible member interposed between the working fluid and the expandable fluid; and
a field generator operable to cause the expandable fluid to change in volume by applying at least one of a magnetic field and an electric field to the expandable fluid, which, in turn, moves the flexible member to increase the pressure of the working fluid to thereby move the working fluid between the first component and the second component. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A peristaltic pump assembly for moving a working fluid comprising:
-
an outer tube;
at least one wire coil embedded within the outer tube, the at least one wire coil operable to generate at least one of a magnetic field and an electric field;
a tubular flexible member disposed within the outer tube, the flexible member including an inner surface that defines a flow channel;
an expandable fluid disposed between the outer tube and the tubular flexible member, wherein the expandable fluid is chosen from a group consisting of an electro-rheological fluid and a magneto-rheological fluid, wherein the expandable fluid is operable to change in volume due to the presence of the at least one of a magnetic field and an electric field generated by the at least one wire coil, wherein the change in volume of the expandable fluid moves the flexible member and reduces the volume of the flow channel to thereby pressurize the working fluid and move the working fluid in the flow channel. - View Dependent Claims (18, 19, 20)
