Fluid manager having a chassis-mounted actuator and a battery including the same

A battery comprising:

• at least one fluid consuming cell comprising:
• a cell housing comprising one or more fluid entry ports for the passage of a fluid into the cell,
• a first fluid consuming electrode disposed within said cell housing, and
• a second electrode disposed within said cell housing;
• and
• a fluid regulating system comprising:
• a valve for adjusting the rate of passage of the fluid into said fluid consuming electrode, said valve comprises a first plate and a second plate each having opposing surfaces adjacent each other, said second plate being movable relative to said first plate so as to open and close said valve,
• a chassis comprising an aperture slidably receiving said second plate, and
• an actuator disposed on said chassis for operating said valve, said actuator is responsive to a cell voltage;
• wherein said chassis completely surrounds said second plate and comprises a first race around at least a portion of said chassis aperture within which said second plate can slidably move, and said first race comprises a portion of a chassis body surrounding said chassis aperture and a first ledge extending inward from said body.
