LIQUID DEVICE HAVING FILTER |
摘要 |
A liquid containing receptacle having a filter is disclosed that in one form includes a nozzle. The filter includes a passage having a portion with a size that restricts the flow of a liquid there through unless sufficient pressure is applied to overcome a liquid and filter property such as surface tension. The pressure in the liquid at the filter can be varied by changing a gas overpressure above a surface of the liquid, changing a head height of the liquid, and/or changing the liquid and filter property, among possible others. In one embodiment the liquid containing receptacle can be used to contain a molten metal that is used in an investment casting mold. The molten metal can be selectively poured into a mold by selectively changing pressure of the molten metal at the filter or by changing the pressure at which molten metal flows through the filter. |
