Abstract
A device for controlling two output elements pivotally mounted with respect to two stationary elements is provided with two coaxial rectilinear double action pressure fluid jacks. The two stationary elements are respectively secured to the ends of a stationary outer longitudinal elongated member while the two pivoting elements are respectively secured to the ends of pivotal inner longitudinal elongated member coaxially arranged in said outer member. The jacks are of annular configuration and formed between the outer and inner aforesaid members with a common median bottom and annularly slotted cylinder-heads remote from each other. The tubular piston rod of each jack extends in leak-tight manner through the annularly slotted cylinder-head and is angularly positioned on the one hand, with respect to the corresponding stationary element by a first set of guides and on the other hand with respect to the corresponding pivoting element by a second set of guides forming an angle relative to the first set of guides. The device is particularly suitable for the control of aircraft flaps.
