Abstract

UNA DISPOSICION PARA APLICAR UNA PRESION TRASERA A UN SELLO DEL EJE (26) DE UN MECANISMO, TAL COMO UNA BOMBA, COMPRENDE UN PISTON (30) DESLIZANTE EN UN CILINDRO, COMUNICANDO UNO DE SUS EXTREMOS CON EL FLUIDO QUE SE ESTA BOMBEANDO Y EL OTRO EXTREMO CONTIENE ACEITE QUE COMUNICA CON UNA CAMARA SELLADA (28) EN ESTE LATERAL DEL SELLO (26) LEJOS DEL FLUIDO. HASTA AHORA, EL PISTON HA CREADO UNA PREPONDERANCIA DE LA PRESION TRASERA SOBRE LA PRESION DEL FLUIDO MEDIANTE SU PESO. ESTA PREPONDERANCIA QUE ERA MUY PEQUEÑA, Y EL SELLO DEL DIAFRAGMA RODANTE NECESITADO SOBRE EL PISTON ROMPIA FACILMENTE SI SE PERDIA ACEITE, LO QUE SE PERMITIA POSIBLES ESCAPES PELIGROSOS DE FLUIDO. SE PROPORCIONA UNA MAYOR PREPONDERANCIA DE LA PRESION TRASERA, QUE PERMITE EL USO DE UN TIPO MAS FUERTE DE SELLO DE PISTON (48, 50, 52), EMPUJANDO EL PISTON (30) HACIA EL OTRO EXTREMO DEL CILINDRO (32) POR UN RESORTE (60) ASI COMO POR LA PRESION DEL FLUIDO. UN IMAN (72) QUE SE ENCUENTRA SOBRE EL PISTON ACCIONA A DISTANCIA UNA SERIEDE SOLAPAS (73) CON GOZMES A LO LARGO DEL EXTERIOR DEL CILINDRO (32) PARA OFRECER UNA INDICACION VISUAL DE LA POSICION DEL PISTON (30), Y TAMBIEN EFECTUA UN RELLENO AUTOMATICO DEL ACEITE SI ES NECESARIO, U OPERA UNA SEÑAL DE AVISO A DISTANCIA CUANDO SE NECESITA RELLENARLO
