发明名称 APARELHO PARA DOSAR UM FLUIDO EM ESCOAMENTO
摘要 <p>Apparatus for dosing a flowing fluid, particularly for dosing an airstream with lubricant. The apparatus includes a casing for connection into the fluid flow line and, within the casing, a cartridge with the additive therein. The cartridge comprises a bag and a nozzle, the nozzle including a metering bore and a spigot which closes the metering bore. Before the cartridge is placed in the casing for use, the spigot is removed so as to open the outlet end of the metering bore. The casing includes a cartridge plate having a stepped aperture therein, the step providing an axially facing shoulder, and the nozzle including a rib which inter-engages with said shoulder to locate the cartridge in the casing. There is a stop element in the bore which is positioned so that it is engaged by said spigot before the rib interengages with the shoulder if an operator attempts to push a nozzle into said bore without having removed the spigot. The preferred form of the stop element is a dished, disc with its concave side facing the nozzle and having a central aperture which exerts some metering influence on additive which has emerged through the metering bore of the nozzle.</p>
