摘要： Vacuum-generating pumping system (SP) comprising a main vacuum pump which is a dry screw pump (3) having a gas inlet intake (2) connected to a vacuum chamber (1) and a gas delivery outlet (4) opening into a pipe (5) discharging the gases to a gas exhaust outlet (8) from the pumping system. The pumping system comprises a nonreturn valve (6) positioned between the gas delivery outlet (4) and the gas exhaust outlet (8), and an auxiliary vacuum pump (7) connected in parallel with the nonreturn valve. The main vacuum pump (3) is switched on to pump the gases contained in the vacuum chamber (1) and deliver these gases via its gas delivery outlet (4), at the same time as the switching-on of the auxiliary vacuum pump (7). Furthermore, the auxiliary vacuum pump (7) continues to pump all the time that the main vacuum pump (3) pumps the gases contained in the vacuum chamber (1) and/or all the time that the main vacuum pump (3) maintains a defined pressure in the vacuum chamber (1).
