Abstract

Die Erfindung betrifft eine Zylinderbaugruppe mit für den Steuerknüppel eines Zykloidalpropellers mit den folgenden Merkmalen:
einem Zylinder (1);
einem in dem Zylinder hin- und herbewegbaren Kolben (3);
einer mit dem Kolben verbundenen Schubstange (9) zum Verstellen von Zykloidalpropellerflügeln;
und einem die Bewegung des Kolbens steuernden Steuerhebel (25), welcher mit der Schubstange (9) gelenkig verbunden ist;
der Zylinder ist ein Hydraulikzylinder.The invention relates to a cylinder assembly for the control stick of a cycloidal propeller with the following features:
a cylinder (1);
a piston (3) reciprocable in the cylinder;
a push rod (9) connected to the piston for adjusting cycloidal propeller blades;
and a control lever (25) which controls the movement of the piston and which is articulated to the push rod (9);
the cylinder is a hydraulic cylinder.

Die Erfindung ist dadurch gekennzeichnet, daß
zwischen die Schubstange und den Steuerhebel eine sowohl mit der Schubstange als auch mit dem Steuerhebel gelenkig verbundene Zwischenstange geschaltet ist,
und daß der Zylinder an seinem schubstangenfernen Ende an einer Trägerstruktur anlenkbar ist.

Figure 00000001
The invention is characterized in that
between the push rod and the control lever there is an intermediate rod connected in an articulated manner both to the push rod and to the control lever,
and that the cylinder is articulated at its end remote from the push rod to a support structure.
