Abstract
EL DISPOSITIVO CONSTA DE UN CUERPO (1,2) CON UNA PRIMERA Y UNA SEGUNDA ABERTURAS (3,4) QUE PUEDEN COMUNICARSE ENTRE SI A TRAVES DE UNA CAMARA (8,9) DEFINIDA EN EL CUERPO Y DESTINADAS A CONECTARSE CON UNA FUENTE DE VACIO Y UN ACUMULADOR U OTRO DISPOSITIVO QUE UTILICE VACIO, RESPECTIVAMENTE. EL CUERPO TIENE ASIMISMO UNA TERCERA ABERTURA (19) A TRAVES DE LA CUAL LA CAMARA (8,9) SE COMUNICA CON LA ATMOSFERA. UNA VALVULA DE CONEXION-DESCONEXION (11,13) ESTA FORMADA EN LA CAMARA (8,9) PARA INTERRUMPIR LA COMUNICACION ENTRE LA PRIMERA Y LA SEGUNDA ABERTURAS (3,4). ESTA VALVULA (11,13) CONSTA DE UN ASIENTO (11) Y UN OBTURADOR MOVIL (13) CONTROLADO POR UN PISTON OPERATIVO (10) QUE SE DESLIZA POR LA CAMARA (8,9) Y QUE SEPARA HERMETICAMENTE LA PRIMERA Y LA SEGUNDA ABERTURAS (3,4) DE LA TERCERA ABERTURA (19). EL PISTON (10) ESTA ADAPTADO PARA CERRAR LA VALVULA (11,13) CONTRA LA ACCION DE ELEMENTO DE EMPUJE ELASTICO (18) QUE TIENEN A ABRIR LA VALVULA (11,13) CUANDO EL VACIO APLICADO A LA SEGUNDA ABERTURA (4) DEL CUERPO SOBREPASA UN VALOR PREDETERMINADO.
