Patent ID: 7855006

Claim:
The combination of a device and a battery for providing energy to the device, the combination comprising at least one fluid consuming electrochemical cell and a fluid regulating system capable of regulating the flow of fluid into the cell, wherein the fluid regulating system comprises: a valve comprising a moveable plate for blocking the flow of a fluid into the cell when the valve is in a closed first position and for passing the fluid therethrough and into the cell when the valve is in a partially or fully open second position; and an electrical circuit comprising: an actuator for moving the valve from said first position to said second position in response to a flow of current therethrough, said actuator including a first end and a second end; a first pair of electrical contacts including first and second electrical contacts that are in contact with each other when the valve is in the first position and are not in contact with each other when the valve is in the second position; and a switch, not inclusive of the pair of electrical contacts, for initially closing the circuit when the valve is in the partially or fully open position, wherein said first electrical contact is mounted on said movable plate and is physically connected to said first end of said actuator in order to anchor said first end of said actuator to said moveable plate.
