Activation mechanism for a reserve battery cell

1. A biasing mechanism for pressurizing an electrolytic solution contained in a chamber of a reserve battery cell, the biasing mechanism comprising:

a compressed spring;

a casing having an opening;

a barrier covering the opening in the casing;

a trigger operatively associated with the compressed spring, wherein the trigger is configured to release the compressed spring to pressurize the electrolytic solution;

a ram that is spring-loaded within the casing via the compressed spring, wherein

the ram is configured to be displaced to puncture the barrier upon release of the compressed spring,

the ram further comprises a pair of apertures,

the trigger comprises a pair of balls inserted into the apertures of the ram to keep the ram spring-loaded, the trigger being configured such that the balls can be pushed from the apertures by the ram to release the compressed spring; and

a trigger sleeve comprising a body that defines a cavity and a pair of apertures, wherein

the trigger further comprises a spacer biased within the cavity via a second spring such that the spacer is held between the balls to keep the balls inserted into the apertures of the ram through the apertures of the trigger sleeve, and

the spacer is configured to be dislodged from between the balls to overcome the bias of the second spring in response to an external force such that the balls are pushed into the cavity by the ram.

2. The biasing mechanism according to claim 1 , wherein the ram comprises a plurality of serrations configured to puncture the barrier upon displacement of the ram.

3. The biasing mechanism according to claim 1 , wherein the trigger further comprises a plug that can dislodge the spacer from between the balls in response to the external force being applied to the plug.

4. The biasing mechanism according to claim 3 , wherein the trigger further comprises a gasket disposed about the plug to prevent a flow of fluid out of the cavity between the plug and the trigger sleeve.

5. The biasing mechanism according to claim 3 , wherein the plug comprises a pair of arms that are spaced apart from one another and are configured to engage the spacer.

6. A method of assembling a biasing mechanism for releasing an electrolytic solution contained in a chamber within a reserve battery cell, the method comprising:

compressing a spring;

providing a casing having an opening;

providing a barrier covering the opening in the casing;

operatively associating a trigger with the compressed spring, the trigger configured to release the compressed spring such that the compressed spring decompresses to pressurize the electrolytic solution;

operatively associating a ram within the casing with the compressed spring, wherein the ram is configured to be displaced to puncture the barrier upon release of the compressed spring, wherein the ram comprises a pair of apertures;

inserting a pair of balls into the apertures of the ram to keep the ram spring-loaded, the trigger being configured such that the balls can be pushed from the apertures by the ram to release the compressed spring; and

providing a trigger sleeve comprising a body that defines a cavity and a pair of apertures, wherein the trigger further comprises a spacer biased within the cavity via a second spring such that the spacer is held between the balls to keep the balls inserted into the apertures of the ram through the apertures of the trigger sleeve; and the spacer is configured to be dislodged from between the balls to overcome the bias of the second spring in response to an external force such that the balls are pushed into the cavity by the ram.
