ABSTRACT:
In one embodiment, a pneumatic power-supply assembly includes a refillable chamber having an interior capable for holding a pressurized fluid, a vent, and a fluid inlet. A pressure release mechanism within the chamber permits the pressure within the chamber to vent, when the pressure exceeds a predetermined optimum pressure. A pneumatic motor is mounted within the chamber and includes an inlet in fluid communication with the interior of the chamber. The pneumatic motor utilizes the pressurized fluid within the interior of the chamber to drive a gear rotatably attached to the pneumatic motor. In addition, the gear rotates an axle rotatably attached to the chamber such that the when the assembly is attached to a pneumatic operated device the rotatable axle may be used by the pneumatically operated device. In addition, a external pump is attached to the fluid inlet to continually recharge the chamber.
