RADIALPUMPE

The pump (1) has a rotor disk (2) supported in a housing (3), and a split-ring slide valve (7) axially movably arranged between the rotor disk and an outlet section (6). A sealing element (8) e.g. O-ring seal, rests on a sealing surface (13) in a closing position of the valve, where the sealing surface is formed by the housing or a housing-fixed part (3a). The sealing element is arranged in a region of a ring-shaped outlet (11) of the valve and is released against the sealing surface in an open position. Another sealing element (9) is arranged at a disk-sided front surface (15) of the valve.

Controllable radial pump for conveying cooling medium for motor vehicle, has split ring feeder secured against rotation and directly mounted on shaft of impeller, and piston rod acting transverse to mechanical force deflecting element

The pump (1) has an impeller (2) mounted in housing (3) through a shaft (2b), and a split ring feeder (7) axial-movably formed between the impeller and an outlet section (6). An actuating element (11) actuates the split ring feeder, and a mechanical force deflecting element (13) is arranged between the split ring feeder and actuating element. The split ring feeder is secured against the rotation and directly mounted on the shaft of the impeller, and a piston rod (12) of the actuating element acts transverse to the mechanical force deflecting element. The split ring feeder is made of carbon-fiber reinforced plastic.

Radialpumpe

Radialpumpe (1) mit einem in einem Gehäuse (3) gelagerten Laufrad (2), mit einem Spaltringschieber (7), welcher zwischen dem Laufrad (2) und einem Austrittsbereich (6) axial verfahrbar ausgebildet ist, wobei zwischen dem Spaltringschieber (7) und dem Gehäuse (3) oder einem gehäusefesten Teil (3a) zumindest ein erstes Dichtelement (8) angeordnet ist, wobei das erste Dichtelement (8) in einer Schließposition des Spaltringschiebers (7) an einer durch das Gehäuse (3) oder den gehäusefesten Teil (3a) gebildeten ersten Dichtfläche (13) dichtend anliegt, dadurch gekennzeichnet, dass das erste Dichtelement (8) im Bereich eines ringförmigen Absatzes (11) des Spaltringschiebers (7) am Spaltringschieber (7) angeordnet ist und in zumindest einer Öffnungsposition gegenüber der ersten Dichtfläche (13) freigestellt ist, und wobei vorzugsweise zumindest ein zweites Dichtelement (9) an einer laufradseitigen Stirnfläche (15) des Spaltringschiebers (7) angeordnet ist.

Radial-flow pump for use as cooling-fluid pump in motor vehicle, has sealing element released against sealing surface in open position, and another sealing element arranged at front surface of split-ring slide valve

The pump (1) has a rotor disk (2) supported in a housing (3), and a split-ring slide valve (7) axially movably arranged between the rotor disk and an outlet section (6). A sealing element (8) e.g. O-ring seal, rests on a sealing surface (13) in a closing position of the valve, where the sealing surface is formed by the housing or a housing-fixed part (3a). The sealing element is arranged in a region of a ring-shaped outlet (11) of the valve and is released against the sealing surface in an open position. Another sealing element (9) is arranged at a disk-sided front surface (15) of the valve.
