1. A vacuum pump having a pump inlet (10), a pump outlet (14) and a pump space (18) for a gas to be pumped, said gas space being arranged between the pump inlet (10) and the pump outlet (14), as well as having at least one cooling gas inlet (48) for a cooling gas for cooling the vacuum pump and having one or more hollow regions (50, 52, 54) for the cooling gas, said one or more hollow regions being connected in a gas conducting manner to the cooling gas inlet (48) and being arranged outside the pump space (18), wherein the or each hollow region (50, 52, 54) is bounded by at least one component (22, 58, 74) of the vacuum pump. |
