Abstract

UNA BOMBA NEUMATICA ELEVADORA DE PRESION, QUE TIENE UNA VALVULA (21) SITUADA PARA OPERAR FIJAMENTE INCLUSO BAJO UNA PRESION DIFERENCIAL CONSIDERABLE. EL INTERIOR DE UN ALOJAMIENTO (1) SE DIVIDE EN UNA CAMARA A PRESION CONSTANTE (3) Y UNA CAMARA A PRESION VARIABLE (4), MEDIANTE UN DIAFRAGMA (2). UN EMBOLO (15), Y UNA VALVULA (21), ESTAN SITUADOS EN UN CUERPO (6) DE VALVULA, SOPORTADO POR UN DIAFRAGMA TAL QUE EL EMBOLO Y LA VALVULA SE DESLIZAN EL UNO RESPECTO AL OTRO. LA VALVULA (22) ESTA FORMADA DE UN MIEMBRO (45) RIGIDO DE REFORZAMIENTO, Y UN MIEMBRO (45) ELASTICO UNIDO AL MIEMBRO DE REFORZAMIENTO. EL EMBOLO ES DESPLAZABLE JUNTAMENTE CON UN EJE PRIMARIO O DE ENTRADA (18). EL DESPLAZAMIENTO DEL EMBOLO SE TRANSMITE A LA VALVULA (21) MEDIANTE UN RESORTE (22) DE VALVULA, QUE HACE QUE LA VALVULA SE SEPARE DE UNA PORCION (19) DE ASIENTO QUE HAY SOBRE EL EMBOLO. DE ESTA FORMA, SE INTRODUCE AIRE COMPRIMIDO DENTRO DE LA CAMARA (4) A PRESION VARIABLE, DESDE UN DISPOSITIVO NEUMATICO, A TRAVES DE CONDUCTOS, PARA CREAR PRESION DIFERENCIAL ENTRE LA CAMARA (4) A PRESION VARIABLE Y LA CAMARA (3) A PRESION FIJA, EN TANTO SE SUMINISTRA CON UNA PRESION NEGATIVA PROCEDENTE DE UN MOTOR, ACCIONANDO ASI EL CUERPO DE VALVULA.
