摘要：The invention relates to an individual blade (7) pitch control device for a

rotorcraft rotor, using rotating linear jacks (29), which are fitted in a rotating support (25),which is driven in rotation together with the rotor. The rods (31) of the jacks (29) actuatethe pitch control levers (24) by rockers (33). The jacks (29) are linear, electrohydraulic,double acting and have at least one body, and are fed by servo control valves (36), whichare likewise mounted in a rotating reference system. These servo valves (36) are fed froma hydraulic circuit in a fixed reference system on the aerodyne by means of at least one atleast partially rotating hydraulic collector (27). ……
