A liquid supply (30, 130, 330) includes a lever (48, 348) that moves in response to expansion and contraction of a variable chamber (42, 342) within a liquid reservoir (56, 356). Movement of the lever (48, 348) moves a ball (52, 352) or sealing member (154, 354) to open or close an opening (60, 360) out of the liquid reservoir (56, 356).
