Abstract

An axial actuator includes an embodiment made of two integrated concentric cylindrical enclosures (1, 3) having differential height. Farthest away from the valve, a piston disk (4) divides the space (A and B) between the two enclosures. A cavity (18) or series of cylindrical cavities (18a) encircle the inner enclosure to acccomodate compression springs (17) and arms of rack gear (4B), projected toward the valve from the rim of said piston disk (4), which engage compounded pinions (G1, G2, G3, G4) where the opposite ends of the compounds pinions are engaged to a main bevel gear (2) nearest to the valve.
When the piston (4) is actuated by actuating means, the hub (23) of the bevel gear (2) actuates the shaft (A) of the quarter turn valve.
