Abstract

Bei einer hydraulischen Verdrängermaschine mit einem in einem Gehäuse gelagerten Rotor, der mindestens einen in einer mit elektrorheologischer/magnetorheologischer Flüssigkeit gefüllten Kammer des Gehäuses ragenden Dehkolben aufweist, wobei der Drehkolben mindestens einen Drehkolbenflügel aufweist, mit über den Umfang der beiden Stirnwände verteilten einzeln elektrisch ansteuerbaren Kondensatorplattensegmente und/oder einzeln elektrisch ansteuerbaren Spulenanordnungen, wobei durch deren Feldbeaufschlagung und der Beeinflussung der dazwischen befindlichen elektrorheologischen/magnetorheologischen Flüssigkeit gebildeten Trennabschnitte einerseits und durch den mindestens einen Drehkolbenflügel andererseits die Saug- und Druckseite gebildet wird, sollen höhere Drücke, größere Durchflüsse und eine höhere Leistungsdichte realisiert werden, dies wird dadurch erreicht, daß mindestens ein Paar einander gegenüberliegende Kondensatorplattensegmente (9) und/oder Spulenanordnungen aufeinanderzu bewegbar ausgebildet sind.

Figure 00000001
In a hydraulic displacement machine with a rotor mounted in a housing, which has at least one expansion piston projecting in a chamber of the housing filled with electrorheological / magnetorheological fluid, the rotary piston having at least one rotary piston wing, with individually electrically controllable capacitor plate segments distributed over the circumference of the two end walls and / or individually electrically controllable coil arrangements, the suction and pressure side being formed by their field application and the influencing of the separating sections formed therebetween on the one hand and by the at least one rotary piston wing on the other hand, higher pressures, greater flow rates and a higher power density are intended This can be achieved in that at least one pair of opposing capacitor plate segments (9) and / or coil arrangements n are designed to be movable towards one another.
