Abstract
Método para formar un aro de pistón destinado a situarse en un surco circunferencial formado en un pistón que puede desplazarse en el orificio del cilindro de un motor de combustión interna, estando dicho aro de pistón constituido por una tira de acero en forma de anillo hendido y teniendo una porción de pared intermedia y un par de paredes laterales que se extienden radialmente hacia el interior a partir es ésta, y estando provisto en su periferia externa un par de superficies cilíndricas separadas dispuestas axialmente para acoplar por transporte de aceite con el agujero de cilíndro y que están situadas respectivamente en el extremo exterior de un reborde rígido macizo que se extiende radialmente hacia el exterior con respecto a la porción de pared intermedia.
