The condensate is conducted to the vater side of the pump while the normal suction line is connected at the pump to the gas 2one. Thus, the water ring pump (10) draws condensate from the lowest point (4) of the jacket (3) to the water side, and gas from the jacket space (3) to the normal suction inlet. During the io process of sterilizer cooling, a stream of water and air (17) from the water ring pump (10) is conducted to the upper part of the jacket space (3) of the steam sterilizer (1) and is allowed to flow as a film down the inner wall of the jacket space (3). Evaporation takes place with cooling of the jacket (3) inner wall. This evaporation is enhanced by the lowering of pressure in the jacket (3) due to the action of the water ring pump (10). Thus, is the autoclave (1) is cooled by a film of water flowing across the jacket (3) inner wall while evaporating.
