Double segment (Machine-translation by Google Translate, not legally binding)

摘要

A double segment, for pistons of all kinds, which, in its essence, consists of being constituted by two pieces or rings superimposed with the recesses that are their own, located in opposite position one from another, with a means of avoiding the relative displacement of said two pieces, consisting of a rectangular projection of the upper ring that penetrates into a notch of the lower one, being imprisoned by the grip that the lower one effects due to its natural elasticity.
