Zusammenfassung:	A drive unit suitable for operating aircraft flight control surfaces comprises a hydraulic multi-piston rotary motor 90. The displacement of the motor 90 is varied through a wobbler 98 whose position is adjusted by a piston unit 73 and a valve 51 responsive to an input command from a valve 11. A feedback link 69 pivotted at 70 contacts a member 53 of the valve 51. A governor valve 50 containing flyweights 55 mechanically coupled to the motor 90 contains a valve member 64 and operates a direction control valve 81.
