Rotary throttle for control and regulation of hydropneumatic automated systems incorporates a housing (1) in which is threaded a revolvable plug (2) with a sealing ring (3) and diametrically opposed holes (6) alignable with an exit port (5) in the housing. The regulating of the throttle aperture is effected by movement of the plug and depends on the pitch of its thread and size and number of the peripheral passages.
