Abstract

CONJUNTO DE EMBOLO (1) Y GUIA (2) DE SU VASTAGO PARA AMORTIGUADORES HIDRAULICOS, COMPRENDIENDO LA GUIA UNA PIEZA ANULAR (3), DOTADA DE UN ORIFICIO CENTRAL (5) Y DE UN ARO ELASTICO (4) DE RETEN. EL EMBOLO (1) ESTA CONSTITUIDO POR UNA SOLA PIEZA (7) FORMADA POR UN CUERPO DE REVOLUCION DE GENERATRIZ (8) CURVO-CONVEXA. LA SUPERFICIE EXTERNA DEL EMBOLO Y LA PARED INTERNA DEL ORIFICIO CENTRAL (5) DE LA PIEZA ANULAR (3), AL MENOS PARCIALMENTE, DE RESPECTIVOS RECUBRIMIENTOS (6, 9) DE GROSOR UNIFORME, DE UN MATERIAL QUE REDUCE LA FRICCION Y MEJORA LA RESISTENCIA AL DESGASTE, COMO POR EJEMPLO DE POLITETRAFLUORETILENO (PTFE) CON UNA CARGA DE PARTICULAS CERAMICAS Y DE UN PIGMENTO. LA CITADA CARGA DE PARTICULAS CERAMICAS Y DE PIGMENTO COMPRENDE PREFERENTEMENTE MULLITA Y OXIDO DE TITANIO. LOS CITADOS RECUBRIMIENTOS (6, 9) DE LA PARED DEL ORIFICIO CENTRAL (5) DE LA PIEZA ANULAR Y DE LA SUPERFICIE EXTERNA DEL EMBOLO (1), TIENEN UN GROSOR UNIFORME COMPRENDIDO ENTRE 20 Y 60 MICRAS.
