A horizontal unit for making beverages using capsules containing powdered food substances comprises a first part (4) and a second part (6) which are mobile between an operating position in which they form an extraction chamber (8) for a capsule (2), and a capsule (2) insertion position in which they are distanced, and movement means (17) for reciprocal movement of the two parts (4), (6) comprising a connecting rod (21) - crank (19) mechanism connected to the mobile part (4), (6). In the operating position the crank (19) rests on a part of the unit supporting structure (3). The crank (19) also comprises at least a first resting portion (56) and/or a second resting portion (58) which in the unit closed position act in contact respectively against at least a first should (57) and/or a second shoulder (59) formed by the supporting structure (3), said shoulders being positioned respectively in such a way as to prevent movements of the crank (19) towards the shaft parallel with the axial line and/or movements of the crank (19) transversally to the plane in which it rotates. |
