GAS GENERATION DISPENSER APPARATUS FOR ON-DEMAND FLUID DELIVERY
First Claim
1. An on-demand fluid dispenser comprising:
- an expandable gas chamber comprising a first moveable structure forming a first wall of the expandable gas chamber and moving along a linear path, the first moveable structure comprising a first mechanism to inhibit movement of the first moveable structure in a backward direction along the linear path;
a second moveable structure forming a second wall of the expandable gas chamber and moving along the linear path, the second moveable structure comprising a second mechanism to inhibit movement of the second moveable structure in the backward direction along the linear path;
a fluid chamber, wherein the first moveable structure forms a wall of the fluid chamber; and
an on-demand gas cell to generate a gas on demand and to direct the gas to the expandable gas chamber to expand the expandable gas chamber, wherein expansion of the expandable gas chamber moves the first moveable structure in a forward direction along the linear path to reduce a volume of the fluid chamber and to dispense an amount of fluid from the fluid chamber, and contraction of the expandable gas chamber moves the second moveable structure in the forward direction along the linear path.

Abstract
An on-demand fluid dispenser to dispense fluid in response to gas generation by a gas cell. The on-demand fluid dispenser includes an expandable gas chamber, a fluid chamber, and an on-demand gas cell. The expandable gas chamber includes a moveable plunger forming a wall of the expandable gas chamber. The moveable plunger also forms a wall of the fluid chamber. The on-demand gas cell is configured to generate the gas on demand. The on-demand gas cell is also configured to direct the gas to the expandable gas chamber to expand the expandable gas chamber. Expansion of the expandable gas chamber moves the moveable plunger to reduce a volume of the fluid chamber and to dispense an amount of fluid from the fluid chamber.
