Abstract
A dashpot type electrolyte ampule for a deferred action battery is descri. The dashpot is designed to provide a damping force which varies as a function of piston position within the ampule. A maximum damping force is provided at the initial position of the piston and a minimum damping force is provided at the further most point of piston travel, just before rupture of the ampule. Various ampule designs are described to provide the variable damping force desired.
Claims11
In an ampule for a deferred action battery including a container with a fluid electrolyte therein, said container having a piston mounted therein and resilient means for normally holding said piston at a first end of said container, means on one end of said piston for puncturing a second end of said container which is opposite said first end, whereby said container, resilient means, electrolyte, and piston form dashpot means for generating a damping force in opposition to the movement of said piston, the improvement in said dashpot means comprising:
- an annular orifice defined by said piston and the walls of said container which increases from a minimum size at said first end of said container to a maximum size at said second end of said container.
