Abstract

EL DISPOSITIVO CONMUTADOR DE FLUJO (10) DE UN APARATO DE IMPULSION DE UN FLUIDO COMPRENDE UN CONMUTADOR (10) ACCIONADO POR LA PRESION DEL FLUJO DEL FLUIDO QUE SE ACTIVA EN CASO DE FALLO O DEGRADACION DEL FLUJO DEL FLUIDO. UN CUERPO (14) CONTIENE EN EL MISMO UN ORIFICIO CIEGO (15) QUE RECIBE UN PISTON (71) EMPUJADO POR UN MUELLE (17) SITUADO EN EL FONDO (13) DEL ORIFICIO (15). UN ALOJAMIENTO DE CONMUTACION (11) QUE ESTA MOLDEADO ALREDEDOR DE UN CONTACTO (20) SE INSERTA DE FORMA ROSCADA EN EL INTERIOR DE UN EXTREMO ROSCADO ABIERTO (16) DEL ORIFICIO. EL ORIFICIO COMUNICA CON UNA ABERTURA PARA EL FLUJO DEL FLUIDO DE MANERA QUE LA PRESION DEL FLUIDO HACE QUE EL PISTON SE CONTRAIGA EN CONTRA DEL MUELLE (17). EL CONTACTO (20) SE EXTIENDE AXIALMENTE MAS ALLA DE UNA PARED (11A) DEL ALOJAMIENTO DEL CONMUTADOR (11) DE MANERA QUE UNA PARTE RADIALMENTE ALARGADA (21) SUMINISTRE UN ASIENTO PARA UN OBTURADOR (30) QUE ENCAJA LA PARTE AXIALMENTE ALARGADA Y UNA SUPERFICIE DEL ORIFICIO. SI EL FLUJO DEL FLUIDOSE DETUVIESE O CALLESE POR DEBAJO DE UN NIVEL DE PRESION PREDETERMINADO, EL PISTON SE DESPLAZARA MEDIANTE LA ACCION DEL MUELLE Y ENCAJARA EN EL CONTACTO PARA COMPLETAR UN CIRCUITO Y ACTIVARA UNA BOMBA DE MOTOR ELECTRICO QUE SUMINISTRA PRESION DE FLUIDO AL APARATO ASOCIADO.
