Abstract
Un cilindro hidraulico con amortiguacion de fin de carrera que comprende al menos un cilindro dispuesto en al menos un embolo, el que esta unido con al menos un vastago del embolo y que se puede desplazar en direccion axial, donde el cilindro se divide desde el embolo en un lado del embolo y un lado del vastago y el aceite hidraulico necesario para la fijacion del embolo es bombeado desde una bomba hidraulica pasando por conductos de entrada y salida a traves de las aberturas de entrada y salida previstas en el cilindro, en que al cilindro se le agrega una preestrangulacion mecanica, a traves de la cual se puede derivar el aceite hidraulico durante el desplazamiento del embolo en el lado del vastago a traves de una primera perforacion en tanto y hasta que el embolo cierre la primera perforacion durante el desplazamiento y con ello derive el aceite hidraulico a traves de una segunda perforacion, desde donde es conducido a una valvula limitadora de presion que, a una presion prefijada, fuerza a la bomba hidraulica en una funcion de corte de presion regulada de forma electronica, que reduce el caudal del aceite hidraulico y conduce al embolo frenado hacia su posicion final
