Abstract

DISPOSICION PARA EL FRENADO FINAL DEL PISTON DE TRABAJO DE UN CILINDRO DE TRABAJO DE DOBLE EFECTO. CARACTERIZADA PORQUE EL CILINDRO DE TRABAJO DE DOBLE EFECTO ESTA SUBDIVIDIDO POR UN PISTON DE TRABAJO (21), PROVISTO DE UNA BIELA (1, 36), EN UNA PRIMERA CAMARA (19) DE MEDIO A PRESION SITUADA EN EL LADO DE LA BIELA, Y EN UNA SEGUNDA CAMARA (22) DE MEDIO A PRESION SITUADA AL OTRO LADO DEL PISTON DE TRABAJO; PORQUE LA BIELA (1, 36) ESTA SUBDIVIDIDA EN UNA PARTE MAGNETIZABLE (36) Y EN UNA PARTE NO MAGNETIZABLE (1); PORQUE EL CILINDRO DE TRABAJO TIENE DOS CONEXIONES (13, 23) PARA EL MEDIO A PRESION, CON UN MANANTIAL DE MEDIO A PRESION, A TRAVES DE UNA VALVULA DE MULTIPLES VIAS; Y PORQUE EN UNA DE LAS CONEXIONES (13) DEL CILINDRO DE TRABAJO SE DISPONE UNA VALVULA DE RETENCION. DE APLICACION EN DISPOSICIONES AUTOMATICAS PARA EL CIERRE DE PUERTAS.
