A device for operating a plurality of pneumatically controlled operative equipments, particularly of the articulated lever type, includes a pressure generator (40) for a gas, which comprises a main cylinder (48) provided with two chambers (56, 58) separated by a slidable piston (54), and an actuator (42) to move the piston (54); fluid lines (34, 36, 60, 62) for connecting the generator unit (40) with at least a chamber (30, 32) of a plurality of pneumatic cylinders (28) of the operative equipments (16), which lines make a closed circuit for the gas, and means (33) for detecting the end-of-stroke position of the levers (18) of said equipments (16), connected with an electronic control unit (ECU). The lines of connection (34, 36, 60, 62) connect the chambers (56, 58) of the main cylinder (48) with the chambers (30, 32) of the cylinders (28) of the equipments (16). |
