Selbsttätige Achsenentlastung für Zentrifugalpumpen, Turbinen und Ventilatoren.
Bei der durch das Stammpatent geschützten Vorrichtung befindet sich von den senkrecht zur Richtung des Achsialschubes liegenden Dichtungsflächen ein Paar in der Nähe des äusseren Kolbenumfanges ; damit ist aber der Ubelstand verbunden, dass eine starke Abnutzung infolge der hohen Geschwindigkeit eintritt, mit der die Dichtungsflächen aneinander vorbeigleiten.
Dieser Umstand gewinnt insbesondere dann Bedeutung, wenn sandhaltiges Wasser zu fördern

Automatic axle relief for centrifugal pumps, turbines and fans.
In the device protected by the parent patent, a pair of the sealing surfaces lying perpendicular to the direction of the axial thrust is located in the vicinity of the outer piston circumference; but this is associated with the disadvantage that severe wear occurs as a result of the high speed at which the sealing surfaces slide past one another.
This fact becomes particularly important when pumping sandy water

there must be resistance by which the pressure p1 is throttled down to the pressure. This resistance arises from the fact that the surfaces cl and c are approximated to a certain extent.

It is further assumed that the axial pressure generated in the pump becomes smaller,

The described relief is not only characterized by the fact that the movement resistance is reduced and the operation is safer, but it is also an important one
