摘要：
The coffee machine (1) comprises a controller, a boiler for heating a flow of infusion water, a movable infusion unit (3) that comprises an open infusion chamber (4) connected to a dispensing line (6) for dispensing the coffee infusion and an ejection piston (9) slidably supported in the infusion chamber (4), a supply line (5) for supplying said flow of infusion water to the infusion unit (3), a closing piston (8) that is engageable for closure of the infusion chamber (4), the controller being programmed to subject the infusion unit (3), prior to execution of the infusion process, to a first course of translational movement for closure of the infusion chamber (4) by the closing piston (8), and to subject the infusion chamber (4) and the ejection piston (9) or only the ejection piston (9), following execution of the infusion process, to a second course of translational movement in the same direction as the first course of translational movement, for compression of the load of spent coffee grounds (33) against the closing piston (8) and drainage of the liquid contained therein.
