<p>An extraction unit (10) for extracting cartridges (la; lb) of two different dimensions (da , ha; db , hb) comprises a seat (14, 20) for receiving any of these cartridges (la; lb) for extraction thereof in the seat. The seat is delimited by a first part (20, 30 , 33) and second part (12, 13, 14) that are relatively movable between a cartridge extraction position and a cartridge loading and/or ejection position. The first delimiting part has a first member (30) and a second member (33) that are relatively movable between: - a first member position delimiting a cartridge cavity of a first depth (Ha) for receiving a cartridge (la) having a first height (ha); and - a second member position in which the cartridge cavity has a second depth (Hb) different to the first depth (Ha) for receiving a cartridge (lb) having a second height (hb) different to the first height (ha). The unit (10) further comprises an actuator (21, 25), in particular a motorized actuator having a motor (21), for relatively moving the first and second members (30 ,33) from the first to the second member position and/or vice versa depending on the dimension (da, ha; db, hb) of a cartridge (la; lb) to be received in the seat (30, 33, 14) and extracted.</p> |
