Abstract

UN DISPOSITIVO (S) DE CONTROL ELECTROHIDRAULICO PARA UN DISPOSITIVO DE SUJECION DE UN TORNO AUTOMATICO, CON UNA VALVULA (V) DE REDUCCION DE PRESION CONECTADA A UNA FUENTE (1) DE PRESION, PUDIENDO ESTAR CONECTADO SU POTENCIA POR MEDIO DE UNA VALVULA (W) DE CONTROL DIRECCIONAL A DOS LINEAS (11,12) UTILIZADORAS OPERABLES DE FORMA ALTERNATIVA, CON UN DISPOSITIVO DE CONEXION DE PRESION COLOCADO EN LA VALVULA (V) DE REDUCCION DE PRESION Y CON UNA ENTRADA (20) DE REGULACION A LA QUE PUEDE SER APLICADA LA PRESION DE CONTROL. EN LA VALVULA (W) DE CONTROL DIRECCIONAL SE DISPONE DE UNA TOMA (Z) DE PRESION DE UTILIZADOR Y EXISTE PRESION DE CONTROL SOLAMENTE EN LA POSICION DE CONTROL (A Y/O B) DE LA VALVULA DE MULTIPASOS DONDE LA POTENCIA (6) DE LA VALVULA (V) DE REDUCCION DE PRESION ESTA CONECTADA DE FORMA PROPIA A UNA LINEA (11,12) DE UTILIZADOR, Y EN DONDE LA TOMA (Z) DE PRESION ESTA CONECTADA A LA ENTRADA (20) DE CONTROL. EN LA VALVULA (V) DE REDUCCION DE PRESION, ENTRE EL EMBOLO (14) DE CONTROL Y EL DISPOSITIVO DE DESCONEXION DE PRESION SE DISPONE DE UN ENLACE MECANICO, DE TRANSMISION DE MOVIMIENTO CON EL CUAL EL DISPOSITIVO DE DESCONEXION DE DEPRESION ES ACTUABLE DIRECTAMENTE MEDIANTE EL EMBOLO (14) DE CONTROL UNA VEZ QUE LA PRESION DE MONITORIZACION AJUSTADA POR MEDIO DE LA FUERZA DEL RESORTE (22) HA SIDO ALCANZADA.
