    摘要: An apparatus for diluting gas. The apparatus has a primary passage having at opposite ends an inlet for component gas and an inlet for a diluent gas, a secondary passage for collecting the mixture of the component gas and the diluent gas, and a plurality of gas pressure reducing tubes each having the same structure for reducing the pressure of gas flowing therethrough by the same amount and which are connected in parallel between the primary passage and the secondary passage. An exhaust outlet has a changeover device connected thereto and a plurality of exhaust passages each has one end connected with the change-over device, one exhaust passage having the other end connected to the primary passage between one inlet and the next adjacent pressure reducing tube, another exhaust passage having the other end connected to the primary passage between the other inlet and the next adjacent pressure reducing tube, and the remaining exhaust passages having their other ends connected to the primary passage between respective pairs of pressure reducing tubes. A pressure control device is connected to the secondary passage for making the pressure of the mixed gas in the secondary passage a definite pressure, and a pressure difference control device is connected between the primary and secondary passages for making the pressure difference between the primary passage and the secondary passage a definite constant value.
