Abstract

Una bomba de paletas de desplazamiento variable que tiene una pluralidad de juntas entre la superficie interior que define la cámara interna de la carcasa y una superficie exterior del anillo de control. Las juntas definen una pluralidad de cámaras de regulación de presión que comprende una primera cámara y una segunda cámara de cada uno para recibir fluido a presión. La primera cámara está definida entre u par de sellos situados en una dirección circunferencial del anillo en los lados del montaje pivotante del anillo de control opuestos y que tienen al menos una entrada para recibir fluido a presión. La extensión circunferencial de la primera cámaras es mayor a lo largo de una porción para aplicar fuerza al anillo en una segunda dirección pivotante a lo largo de una porción para aplicar fuerza en la primera dirección pivotante de tal manera que una fuerza neta ase aplica en la segunda dirección pivotante. La segunda cámara está definida entre un par de juntas situadas en la dirección circunferencial del anillo y tiene al menos una salida para recibir fluido a presión de tal manera que toda la extensión circunferencial de la segunda cámara aplica una fuerza al anillo en la segunda dirección pivotante.
