In addition, this valve closure body has two one behind the other, the other two shut-off valves forming shoulders, which two the scope of the valve limit the body surrounding circumferential grooves. ùie for making the Connection between the cannulas dispensing from the servo valve with the ducts leading to the servo motor are used. The servo valve and the three shut-off valves are advantageously located in a common housing which is attached directly to the cylinder of the servo motor or which forms a whole with the cylinder housing of the servo motor.

Auf der Zeichnung ist schematisch ein Ausführungsbeispiel der Neuerung dargestellt. An exemplary embodiment of the innovation is shown schematically in the drawing shown.

Hierbei ist der Servomotor mit 10 bezeichnete dessen Zylinder 11 den hin und her verschiebbarem Kolben 12 enthält, der an einer Kolbenstange 13 sitzt) die an beiden Stirnseiten aus der Zylinder 11 hervorsteht. Die Stange hat überall gleichen Durchmesser. In this case, the servomotor is its cylinder 11, denoted by 10 contains the reciprocating piston 12, which sits on a piston rod 13) which protrudes from the cylinder 11 at both ends. The pole has everywhere same diameter.

Ferner ist ein Servoventil 14 vorgesehen, dessen Gehäuse 15 unmittelbar am Servomotor 10 sitzt oder aber ein Ganzes mit dem Gehäuse des Servomotors bildet. Dieses Servoventil hat einen Kolben 16 der in der Bohrung 17 des Gehäuses 15 verschiebbar ist.Furthermore, a servo valve 14 is provided, the housing 15 of which is seated directly on the servomotor 10 or as a whole forms the housing of the servomotor. This servovalve has one Piston 16 which is displaceable in the bore 17 of the housing 15.

Der Kolben weist am Umfang zwei Nuten 18 19 auf, welche durch drei Schultern 20, 21, 22 begrenzt sind.
