A fluid-driven multi-cylinder operating unit, particularly for tire removal machines comprising a rotor (3) with a radial series of equidistant coplanar, single-acting cylinder-piston units (5, 6) fed in succession by an annular distributor (15), with their rods interacting, by way of end rollers (9), with a track (10) which is coaxial to the rotor (3) and fixed to the stator (1) and which includes a succession of semicylindrical cavities (11) in a number less than the number of cylinder-piston units (5, 6) and joined together by cusps (12); there being provided a valve for throttling the pressurized fluid feed pipe to said cylinder-piston units.
