Abstract

LA PRESENTE INVENCION PRESENTA UN DISPOSITIVO DE SUSPENSION PARA UN VEHICULO QUE CONSTA DE UN ACCIONADOR (11) QUE TIENE UN PISTON (12) COLOCADO DENTRO DE UN CILINDRO (13), CUYO PISTON (12) DIVIDE AL CILINDRO (13) EN DOS CAMARAS POR LO MENOS (A Y B), ACTUANDO UNA PRIMERA SUPERFICIE DEL PISTON (12) EN UNA PRIMERA CAMARA (B) DEL CILINDRO QUE TIENE UN AREA MENOR QUE LA SEGUNDA SUPERFICIE DEL PISTON (12) QUE ACTUA EN UNA SEGUNDA CAMARA (A). EL DISPOSITIVO CONSTA TAMBIEN DE UNA FUENTE DE SUMINISTRO DEL FLUIDO A PRESION (16), UN ORIFICIO PARA LA SALIDA DEL FLUIDO A PRESION (19) Y UNA VALVULA (30). LA VALVULA (30) TIENE UN PRIMER Y UN SEGUNDO MODO DE FUNCIONAMIENTO. EN EL PRIMER MODO DE FUNCIONAMIENTO, LA VALVULA CONECTA LA PRIMERA CAMARA (B) A LA FUENTE DE SUMINISTRO DEL FLUIDO A PRESION (16) Y CONECTA DE MANERA SELECTIVA LA SEGUNDA CAMARA (A) BIEN A LA FUENTE DE SUMINISTRO DEL FLUIDO A PRESION (16) O BIEN AL ORIFICIO DE SALIDA DEL FLUIDO A PRESION (19), DETERMINANDO LA VALVULA (30) EL CAUDAL DE FLUIDO QUE ENTRA O SALE DE LA SEGUNDA CAMARA (A) PARA CONTROLAR EL MOVIMIENTO DEL PISTON. EN EL SEGUNDO MODO DE FUNCIONAMIENTO, LA VALVULA (30) CONECTA LA SEGUNDA CAMARA (A) A LA FUENTE DE SUMINISTRO DEL FLUIDO A PRESION (16) Y CONECTA LA PRIMERA CAMARA (B) AL ORIFICIO DE SALIDA DEL FLUIDO A PRESION (19), DETERMINANDO LA VALVULA EL CAUDAL DE FLUIDO PROCEDENTE DE LA PRIMERA CAMARA (B) PARA CONTROLAR EL MOVIMIENTO DEL PISTON. EN UN ASPECTO PREFERENTE DE LA INVENCION, EL ACCIONADOR (11) SOPORTA, JUNTO CON UN ELEMENTO DE RESORTE (35), PARTE DEL PESO ESTATICO DEL VEHICULO.
