Abstract
"APARELHO DE ADMISSãO DE AR APERFEIçOADO PARA UMA BOMBA DE VáCUO DE ANEL LìQUIDO". Um aparelho de admissão de ar aperfeiçoado para uma bomba de vácuo de anel líquido é descrito, tendo uma porta de admissão de gás que possui uma área de seção reta, um conduto comunicando com a porta de admissão de gás. O conduto possui uma área de seção reta substancialmente igual à área de seção reta da porta de admissão de gás. Então, uma porta de saída de gás comunica com o conduto e a bomba de vácuo de anel líquido. A porta de saída de gás possui uma área de seção reta substancialmente igual à área de seção reta do conduto. O aparelho de admissão de ar aperfeiçoado tem também uma "boca" possuindo uma área de seção reta, um caminho de passagem de saída em comunicação com a "boca", uma área de seção reta substancialmente igual à área de seção reta da "boca" uma porta de descarga em comunicação com o caminho de passagem de saída, e uma área de seção reta substancialmente igual à área de seção reta do caminho de passagem de saída."PERFECTED AIR INTAKE APPLIANCE FOR A NET RING VACUUM PUMP". An air intake device optimized for a liquid ring vacuum pump is described, having a gas intake port that has a straight section area, a conduit communicating with the gas intake port. The duct has a straight section area substantially equal to the straight section area of the gas inlet port. Then, a gas outlet port communicates with the flue and the liquid ring vacuum pump. The gas outlet port has a straight section area substantially equal to the straight section area of the duct. The improved air intake device also has a "mouth" having a straight section area, an outlet passage path in communication with the "mouth", a straight section area substantially equal to the straight section area of the "mouth" a discharge port in communication with the exit passage path, and a straight section area substantially equal to the straight section area of the exit passage path.
