Abstract
A machine for preparing liquid products via cartridges comprises a delivery assembly that includes at least: one injector device, to introduce into a cartridge water and/or steam under pressure; an infusion chamber, facing the injector device and designed to receive the cartridge; an actuation system, designed to cause relative displacements between the injector device and the infusion chamber, between a spaced position and a closed position; a loading arrangement that includes an inlet duct and retention means, which can be switched between a retention condition, where the cartridge is kept in a position substantially coaxial to the infusion chamber and to the injector device, and a release condition, where the cartridge is free to fall towards an outlet passage of the delivery assembly. The injector device, the infusion chamber, and the retention means are prearranged for obtaining a switching of the retention means from the retention condition to the release condition by means of a relative displacement between the injector device and the infusion chamber.
