Abstract

La presente invención se refiere a un dispositivo de ajuste para ajustar el ángulo del grado inclinación de las aspas propulsoras (4) de una bomba impulsora (1), y una bomba impulsora que incorpora este dispositivo. El dispositivo de ajuste comprende medios de ajuste (5;25;35) montados dentro del disco central (2) dispuesto para ser axialmente móvil en una dirección a lo largo del eje impulsor (7), estando los medios de ajuste (5;25;35) provistos con una pluralidad de ranuras de guiado (6;26a;26b;36) dispuestas con separaciones circunferenciales alrededor de la superficie; una pluralidad de medios de fijación (20) montados, a través de la rotación, en el disco central (2), estando cada uno de ellos acoplado de manera fija a una aspa propulsora (4) y soportado por al menos una ranura de guiado (6;26a;26b;36), en el que cada medio de fijación (20) y la correspondiente por lo menos una ranura de guiado (6;26a;26b;36) está dispuesta de manera que interactúa de manera tal que una fuerza aplicada sobre el medio de fijación (20) se distribuye simétricamente alrededor de un eje perpendicular al eje impulsor (7) y paralelo a un eje rotacional del medio de fijación (20); y en la que las ranuras de guiado (6;26a;26b;36) están dispuestas de manera tal que, al tener lugar un movimiento axial de los medios de ajuste (5;25;35), ocasionan que el medio de fijación (5;25;35) rote alrededor de su propio eje rotacional, con lo cual a su vez se hace rotar el aspa propulsora (4).The present invention relates to an adjustment device for adjusting the angle of the inclination degree of the propeller blades (4) of a driving pump (1), and a driving pump incorporating this device. The adjustment device comprises adjustment means (5; 25; 35) mounted within the central disk (2) arranged to be axially movable in a direction along the drive shaft (7), the adjustment means (5; 25 being) ; 35) provided with a plurality of guide grooves (6; 26a; 26b; 36) arranged with circumferential separations around the surface; a plurality of fixing means (20) mounted, through rotation, on the central disk (2), each of them being fixedly coupled to a propeller blade (4) and supported by at least one guide groove (6; 26a; 26b; 36), in which each fixing means (20) and the corresponding at least one guiding groove (6; 26a; 26b; 36) is arranged so that it interacts such that a force applied on the fixing means (20) is distributed symmetrically around an axis perpendicular to the driving shaft (7) and parallel to a rotational axis of the fixing means (20); and in which the guide grooves (6; 26a; 26b; 36) are arranged such that, when an axial movement of the adjustment means (5; 25; 35) takes place, they cause the fixing means ( 5; 25; 35) rotate around its own rotational axis, which in turn rotates the propeller blade (4).
