Abstract

Un pistón perfeccionado para frenos de disco, tipo que comprende una porción cilíndrica mayor con una cara externa sometida a presión de fluido, con el funcionamiento del pistón, y una porción cilíndrica menor de inferior diámetro que la porción mayor y contigua a ésta, formándose un espaldón anular entre las superficies cilíndricas de dichas porciones, y presentando el pistón una cavidad ciega extendida axilmente, que desemboca en una cara extrema de la porción menor, caracterizado porque el pistón (4) se obtiene a partir de resina plástica, el espaldón (10) se forma con una superficie redondeada (11) y la citada cara extrema (12) de la porción mayor (8) tiene una superficie cóncava parcialmente esférica (14).
