Abstract

LA VALVULA TIENE SU CHAPELETA O TRAMPILLA (19) UNIDA EN MOVIMIENTO AL EMBOLO-BUZO (20) DE UN SOLENOIDE (21) DE ABERTURA DE LA CHAPELETA, Y A LA MEMBRANA (12) IMPULSADA POR UN RESORTE (22) DE RETORNO HACIA EL CIERRE DE LA CHAPELETA SOBRE LA SALIDA (18) UNIDA AL CONDUCTO DE ADMISION DEL MOTOR. LA CAMARA (14) DE LA CHAPELETA (19) ESTA UNIDA AL CANISTER A TRAVES DEL CALIBRADOR FIJO (17) LA CAMARA (13) DEL OTRO LADO DE LA MEMBRANA (12) ESTA A LA PRESION ATMOSFERICA O A LA PRESION DEL CANISTER. LA DEPRESION QUE ACTUA SOBRE EL CALIBRADOR (17) SE APLICA A LA MEMBRANA (12) IGUALMENTE SOMETIDA A LOS ESFUERZOS DEL RESORTE (22) Y DEL SOLENOIDE (20 GENERACION DEL CANISTER A TRAVES DEL CALIBRADOR (17) DE FORMA CONTINUA, MEDIANTE UNA DEPRESION VARIABLE CONDUCIDA POR LA MODULACION DE LA CORRIENTE MEDIA DE MANDO DEL SOLENOIDE. APLICACION DE LA VALVULA PROPORCIONAL AL CONSUMO CONTINUO PARA LA REGENERACION DE CANISTER DE MOTOR DE COMBUSTION INTERNA.THE VALVE HAS ITS PADDLE OR TRAMP (19) MOVED TO THE PLUNGER-DIVER (20) OF A SOCKET OPENING SOLENOID (21), AND TO THE MEMBRANE (12) PUSHED BY A RETURN SPRING (22) OF THE PADDLE ON THE OUTLET (18) ATTACHED TO THE ENGINE INTAKE DUCT. THE CHAMBER (14) OF THE CHAPELETA (19) IS ATTACHED TO THE CANISTER THROUGH THE FIXED GAUGE (17) THE CHAMBER (13) ON THE OTHER SIDE OF THE MEMBRANE (12) IS AT ATMOSPHERIC PRESSURE OR CANISTER PRESSURE. THE DEPRESSION ACTING ON THE CALIBRATOR (17) APPLIES TO THE MEMBRANE (12) ALSO SUBMITTED TO THE EFFORTS OF THE SPRING (22) AND THE SOLENOID (20 GENERATION OF THE CANISTER THROUGH THE CALIBRATOR (17), BY A DEPRESSION VARIABLE DRIVEN BY THE MODULATION OF THE AVERAGE CONTROL CURRENT OF THE SOLENOID APPLICATION OF THE PROPORTIONAL VALVE TO CONTINUOUS CONSUMPTION FOR THE REGENERATION OF THE INTERNAL COMBUSTION ENGINE CANISTER.
