Abstract

Bei einem Druckmittelmotor für elektrorheologische Flüssigkeiten, mit einem zwei Arbeitskammern (A, B) umgebenden Gehäuse (1), einem in dem Gehäuse (1) bewegbaren Kolben (3), einem Einlaßkanal (22) für die Zuführung und einem Auslaßkanal (23) für die Abführung einer elektrorheologischen Flüssigkeit und elektrorheologischen Ventilen (1a, 1b, 2a, 2b) mit einem jeweils eine Arbeitskammer (A bzw. B) mit dem Einlaßkanal (22) oder dem Auslaßkanal (23) verbindenden Ringspalt (8), dessen Begrenzungsflächen Elektroden zur Erzeugung eines elektrischen Feldes bilden, werden die elektrorheologischen Ventile (1a, 1b, 2a, 2b) durch die Gehäusewand in Längsrichtung durchdringende Bohrungen (6) und in den Bohrungen (6) angeordnete, gegenüber dem Gehäuse (1) isolierte Dorne (7) gebildet, wobei die Bohrungen (6) und die Dorne (7) miteinander Ringspalte (8) konstanter Spaltweite begrenzen und die Dorne (7) an eine Hochspannung und das Gehäuse (1) an Massepotential anlegbar sind.

Figure 00000001
In a pressure medium motor for electrorheological liquids, with a housing (1) surrounding two working chambers (A, B), a piston (3) movable in the housing (1), an inlet channel (22) for the feed and an outlet channel (23) for the discharge of an electrorheological fluid and electrorheological valves (1a, 1b, 2a, 2b) with an annular gap (8) connecting a working chamber (A or B) to the inlet channel (22) or the outlet channel (23), the boundary surfaces of which electrodes for To generate an electric field, the electrorheological valves (1a, 1b, 2a, 2b) are formed by bores (6) which penetrate in the longitudinal direction through the housing wall and mandrels (7) arranged in the bores (6) and insulated from the housing (1) , wherein the bores (6) and the mandrels (7) delimit annular gaps (8) of constant gap width and the mandrels (7) can be connected to a high voltage and the housing (1) to ground potential.
