Abstract

Bei einem elektrohydraulischen Betätigungsgerät, umfassend eine in einem Gehäuse (1) angeordnete, von einem Elektromotor (2) angetriebene Pumpe (3), wobei das von der Pumpe abgegebene Druckmittel einen im Gehäuse geführten Kolben (4; 30) beaufschlagt, dessen Kolbenstange (7) als Betätigungselement aus dem Gehäuse (1) vorsteht, wird zur Erzielung einer möglichst kompakten Bauform der hochdruckseitige Zylinderraum (5, 5a) des Kolbens (4; 30) um einen Abschnitt der Pumpe (3) bzw. um einen Abschnitt der Motor-Pumpeneinheit ausgebildet.

Figure 00000001
In an electrohydraulic actuating device comprising a pump (3) arranged in a housing (1) and driven by an electric motor (2), the pressure medium emitted by the pump acting on a piston (4; 30) guided in the housing, the piston rod (7 ) protrudes from the housing (1) as an actuating element, the cylinder chamber (5, 5a) of the piston (4; 30) around a section of the pump (3) or a section of the motor-pump unit is compressed to achieve the most compact possible design educated.
