Action
When the gun recoils on firing it draws the
buffer cylinder with it to the rear, the liquid in the cylinder
in passing from front of piston to its opposite side is forced
through grooves in the cylinder, which owing to there [sic] shape
gradually diminish the space for the flow of the liquid
and brings the gun to rest, meanwhile the running out springs
have been further compressed, there [sic] subsequent expansion
causes the gun to return to the firing position, and in doing
so the controlling plunger displaced the liquid in the rear.
