Abstract:
1. A delivery assembly for a machine for preparing liquid products by means of cartridges that have a substantially cup-shaped body that houses an amount of at least one substance capable of forming a liquid product via water and/or steam, the delivery assembly having a substantially horizontal axis and including: an injector device, capable to introduce into a cartridge water and/or steam under pressure; an infusion chamber facing the injector device and capable to receive one said cartridge; an actuation system, capable to cause displacements of the infusion chamber between a spaced position and a close position with respect to the injector device, the delivery assembly also comprising a loading arrangement that includes an inlet passage and retention means, wherein the inlet passage is capable of enabling insertion of a cartridge into the delivery assembly and the retention means are capable of maintaining the cartridge in a position substantially coaxial to the infusion chamber and to the injector device, wherein the retention means are switchable between a retention condition and a release condition of the cartridge by means of said displacements of the infusion chamber with respect to the injector device, wherein the delivery assembly further comprises ejector means, which are functionally distinct from said retention means and capable to push the cartridge towards the outside of the infusion chamber in function of the displacement of the infusion chamber towards its spaced position with respect to the injector device, and wherein the delivery assembly also comprises coupling means borne by the infusion chamber, the coupling means being capable of assuming a condition of engagement and a condition of disengagement with respect to a cartridge in the course of the displacement of the infusion chamber towards said close position and towards said spaced position, respectively.
