PURPOSE:To supply arbitrary amounts of two or more kinds of liquids at the constant rate by providing a plurality bellows containers having a cross sectional area rate corresponding to the ratio of a plurality of the liquids to be supplied, and providing a means to compress all the bellows by the same distance at the same time. CONSTITUTION:A plurality of the tubular bellows 1 and 1', which have the cross sectional area ratio corresponding to the ratio of a plurality of the liquid to be supplied and can be freeely expanded and contracted, are placed on a horizontal surface by supporting tables 5 and 5' in the up and down direction. On the bellows containers 1 and 1', liquid injecting ports 3 and 3', which are hermetically closed by freely detachable caps 4 and 4', are provided. Liquid outlet ports 2 and 2' are provided at the lower ends. An air cylinder 8, which applies a load to a compressing plate 6 that simultaneously compresses the bellows containers 1 and 1' by the same distance, is provided. The air cylinder 8 performs the required operation when the air is sent into either of a cylinder lowering air supply port 9 or a cylinder lifting air supply port 10. The constant rate liquid supplying device obtained in this way can be used e.g. in spray coating and the like. |
