The device (10) has a lip seal (21) closing a chamber (20) between a bell shaped stator (11) and a rotor (12). The rotor defines a chamber (30). Pneumatic ports (15, 17) respectively open out from the chambers. The chambers are communicated when a valve (32) carried by the rotor is opened. An electromechanical actuator (24) switches the valve between stable closed and open states. The stator is received as push-fit in an axle and includes a base wall (19) carrying the port (15) to connect the device to a pneumatic unit by a pipe (16) running into the axle. The rotor extends inside the stator. |
