A dispensing assembly (30) for a machine for the preparation of liquid products using capsules includes: an injector device (50), for introducing into a capsule (10) water and/or steam under pressure; a capsule holder (40), facing the injector device (50) and designed to receive the capsule (10); and an actuation linkage (80), for causing displacements of the capsule holder (40) between a spaced position and a close position with respect to the injector device (50). The dispensing assembly (30) further includes ejector means (70), which are designed to push the capsule (10) towards the outside of the capsule holder (40) according to the displacement of the capsule holder (40) towards its spaced position from the injector device (50). The ejector means (70) are mechanically constrained to the actuation linkage by means of a mechanical connection.
