Abstract
Pistón perfeccionado por resorte neumático u otro sistema telescópico con cilindro y varilla introducible, estando el aludido pistón destinado a montarse deslizante dentro del cilindro y a guiar aquella varilla, así como a subdividirlo en dos cámaras neumáticas, situadas a una y a otra parte de tal pistón y unidas entre si por un paso calibrado practicado a través del repetido pistón, el cual se caracteriza por el hecho de que, siendo monobloque y estando constituído totalmente de una sola y única pieza homogénea obtenida por moldeo, el mismo presenta una configuración geométrica elaborada definida por una profunda garganta anular que as extiende alrededor, de un alma central maciza prácticamente indeformable y que separa esta última de un faldón periférico flexible que se aplica, de modo estanco y deslizante, contra la pared del cilindro, siendo la materia de este pistón monobloque así conformado una resina acetal (polímero de formaldehído) designada con la marca "Delrin" o cualquier otramateria plástica similar de débil coeficiente de roce.
