Espresso coffee machine

An espresso coffee machine comprising:

• a work station (14), a loading station (13) and an unloading station (18) for wafers (6), said loading and unloading stations (13, 18) being separate from said work station (14);
• a boiler (35) having an outlet (38) for providing a stream of hot water;
• a spout (17);
• supply means (41) for supplying pressurized water to said boiler (35);
• a conveyor disk (8) having a number of seats (11) respectively for said wafers;
• actuating means (20) for rotating said conveyor disk (8) in steps about an axis (7) to successively feed said seats (11) through said loading (13), work (14) and unloading (18) stations, each one of said seats (11) and, thereby, said wafers (11) being interposed at said work station (14) between said outlet (38) and said spout (17);
• hydraulic connecting means (34) connected hydraulically to said supply means (41) in parallel to said boiler (35) for connecting said outlet (38) and said one of said seats (11) interposed at said work station (14) in a fluidtight manner;
• a pusher (40) located at said unloading station (18);
• and
• a hydraulic actuator (33) connected hydraulically to said supply means (41) and connected mechanically to said pusher (40) to move said pusher (40) through each of said seats (11) as successively fed through said unloading station (18) between a raised idle position and a lowered operating position.
