Abstract

Perfeccionamientos en los cilindros hidráulicos lineales, dotados de medios amortiguadores para amortiguar el impacto del pistón sobre el cilindro en un extremo o en cada extremo de su carrera, caracterizados porque los medios amortiguadores comprenden un elemento sellador cilíndrico llevado por el vástago del pistón y susceptible de cooperación con una cara de sellado anular cerca de un primer extremo del cilindro para sellar el espacio del cilindro entre el pistón y el elemento sellador a medida que el pistón se acerca a dicho extremo, y porque el cilindro comprende además un paso de fuga restringida en la pared del cilindro que pone en derivación la superficie de sellado para permitir el escape de fluido de dicho espacio de cilindro, siendo susceptible el elemento sellador cilíndrico de desplazamiento axial hacia el pistón contra un fuerza elástica.
