Abstract (en)
[origin: EP0541046A1] Propeller pump with blade pitch adjustment, whose adjustment apparatus [lacuna] by a threaded spindle (8), an adjustment nut (11) axially adjustable thereon which is provided with a slide bar (14, 15) and, via a guide bar bracket (13, 7) arranged in the propeller hub (1, 2), determines the position of the blades (4) [lacuna]. Reduced manufacturing effort, while maintaining the guidance and bearings quality, is achieved by the slide bar (14, 15) being arranged in the propeller hub (1, 2) and comprising guide rods (15) whose ends are retained at the cover and at the bottom flange of the propeller hub (1, 2). The rods (15) may be rifled and may interact with simple guide bores (14). <IMAGE>
