A rotary distributor device comprises rotors (10) each having a central longitudinal bore (19) and lateral inlet (111) and exhaust (112) ports, and also peripheral inlet (117) and exhaust (118) ports. A control shaft (9) having alternating sections (92, 93) of different diameter linked together by transition surfaces (94) slides in the longitudinal bore (19). First and second means (30, 40, 50) are provided on the lateral face (11, 12) of each rotor (10) to partially cover and adjustably uncover the lateral (111, 112) and peripheral (117, 118) ports, said means (30, 40, 50) being arranged to cooperate with the sections (92, 93) and the transition surfaces (94) of the control shaft. |
