<p>An injection device, e.g. for the metering of textile softener products in wash tubs, automatically supplies product(s) into water fed to the tub by means of an electrovalve sluice. The temp, and thus the viscosity of the products is maintained by a double-walled container, so that the precision of the dosage is improved. The two walls confine a space which is connected to a water discharge tube feeding the tube of a household appliance. This space surrounds a container which is connected to the flask of the product. The injection process is effected by suction, using a metering system described in the parent patent.</p> |
