Abstract
The present invention relates to a unit for the preparation of infusions comprising a stationary piston, a mobile chamber () and a mobile piston concentric to the mobile chamber, arranged to co-operate for the preparation of infusions and to generate a tablet of exhausted powder apt to be ejected by an ejection device (). The unit comprises also a plate () moved by a motor and elastically linked to the mobile chamber () so that such a resilient link is arranged to allow relative movement of the chamber () as to the plate () and to induce the activation of the ejection device. Advantageously, the resilient link between the plate and the chamber makes the unit of particularly simple realization. The invention also relates to an infusion machine, to the ejection device and to a method for realizing the unit.
