Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE DESCONEXION HIDRAULICA EN LAS POSICIONES FINALES DE UN SERVOCILINDRO. LOS DISPOSITIVOS DE DESCONEXION O CIERRE DE ESTE TIPO ESTAN DISEÑADOS PARA IMPEDIR EL CONTACTO DURO DIRECTO ENTRE EL PISTON EN FUNCIONAMIENTO (31) Y LOS TOPES LIMITADORES (47, 48) A LA PRESION DE TRABAJO, Y PARA PERMITIR LA RETIRADA DE LAS POSICIONES FINALES CON ASISTENCIA HIDRAULICA. LA INVENCION SE CARACTERIZA PORQUE UNOS PISTONES LOCOS (32, 33), CON UNA POSIBILIDAD LIMITADA DE DESPLAZAMIENTO, SE ENCUENTRAN SITUADOS SOBRE EL PISTON DE TRABAJO (31). LOS PISTONES LOCOS (32, 33) ACTUAN COMO CIERRE, ADAPTANDOSE FIRMEMENTE CONTRA LOS BORDES DE SELLADO (34, 35) DEL PISTON DE TRABAJO. LOS BORDES DE CIERRE (34, 35) CONTROLAN UN CANAL DE DERIVACION (36) SITUADO EN EL PISTON DE TRABAJO (31). SE INSERTA UN MUELLE (41) ENTRE LOS PISTONES LOCOS (32, 33), EN UNA CAMARA (40) QUE PUEDE ESTAR A PRESION. CUANDO EL PISTON DE TRABAJO (31) SE PONE EN CONTACTO, POR EJEMPLO, CON EL TOPE LIMITE (48)DEL MANGUITO (43), EL COLLARIN (45) SEPARA UN PISTON LOCO (33) DEL BORDE DE CIERRE (35). LA UNION CON LA CAMARA (40) OCURRE A TRAVES DEL CANAL DE DERIVACION (36), CON LO QUE LA PRESION DE TRABAJO EMPUJA AL PISTON LOCO (32) DE NUEVO CONTRA EL MUELLE (41), ALEJANDOLO DE SU BORDE DE CIERRE (34). LA PRESION DE TRABAJO PUEDE ENTONCES CAER ENTRE LA CAMARA A PRESION (37) Y LA CAMARA A PRESION (38) HASTA QUE EL MUELLE (41) VUELVE A SELLAR EL PISTON LOCO (33) CONTRA EL BORDE DE CIERRE (34). LA PRESION QUE SE REGULA ASI EN LA CAMARA DE PRESION (37) SOSTIENE EL PISTON DE TRABAJO (31), JUNTO CON EL PISTON LOCO (32, 33) EN LA POSICION FINAL. NO OBSTANTE, LA PRESION ASI AJUSTADA SE ENCUENTRA POR DEBAJO DE SU VALOR MAXIMO.
