Abstract

Esta estructura de pistón para amortiguador de impactos, está constituida por la asociación de dos piezas anulares extremas, según su posicionado en el pistón, que están reunidas por una pieza anular central, también según su posicionado en el pistón, presentando las tres piezas su orificio central diametralmente dimensionado en forma ajustada al vástago del pistón en la pieza anular central y en forma holgada en las restantes dos piezas anulares extremas, las cuales son diametralmente mayores que la pieza anular central, la cual encaja entre aquellas, en su acoplamiento, conformando entre dichas tres piezas una ranura perimetral de asiento para una junta elástica. Es de principal aplicación en la industria del automóvil.
