ABSTRACT:
The device relates to the distribution under pressure of the hot water coming from a tank, boiler or the like in a coffee-machine and the delivering of the water itself to the chamber where the coffee powder is contained, as well as the filtering of the infusion obtained by the passing of the hot water through the coffee powder as far as the coming out of the infusion itself. The device allows to avoid the clogging of the inlet holes of the hot water into the chamber containing the coffee powder and the clogging or the variation of the holes of the usual filters through which the infusion passes so that the total passing surface of the infusion for filtering remains constant in the time. For filtering the infusion, the device provides a solid disk having a central hole the outer diameter of which is smaller than the diameter of the chamber containing the coffee powder and the inner diameter is partially closed, the whole so that in all the infuse passing port is equivalent to what is considered the optimum surface of the usual filters, which is formed by the addition of all the surfaces of the single passing holes through the filter. The infusion water is then let into the chamber containing the coffee powder, passes through the same and comes out from the circular peripheral and central crowns laying between the disk and the containing chamber, coming out from the outlet holes of the unit.
