ABSTRACT:
The rotating and non-rotating swash-plates are guided in axial translation and in tilting on the rotor axis by a non-rotating axial guide arrangement, such as two pillars, and slides on each of which slides one of two pads carrying diametrically opposite trunnions, enabling the pivoting of the non-rotating plate around a first diametrical axis, whereas the sliding movements of the pads on the slides guide the pivoting movements of the non-rotating plate around a second diametrical axis perpendicular to the rotor axis and first diametrical axis, and which is the axis of the cylindrical face of the slides.
