The pumping circuit is equipped with an over-pressure valve (25) that is mounted directly downstream of a liquid-ring tank (21), where the gas passing through the valve in discharge mode is re-aspirated by a vacuum pump (16) mounted on the circuit. An independent claim is also included for a process for implementing the use of a tank device.",
