1. An adapter for beverage preparation machines, comprising a supporting element which can be associated with water dispensing means by means of a bayonet coupling of said adapter, and a cartridge holder associated with said supporting element, said cartridge holder comprising a plurality of receptacles for respective cartridges for infusions, said cartridge holder being movable with respect to said supporting element from a position for dispensing the infusion to a position for loading and unloading said cartridges, said supporting element being provided with a front opening for moving said cartridge holder from said position for dispensing the infusion to said position for loading and unloading said cartridges and vice versa, wherein said adapter comprises at least one guide for the translational motion of said cartridge holder with respect to said supporting element, said at least one guide comprising a first straight portion which is adapted to allow a sliding of said cartridge holder with respect to said supporting element between two intermediate positions comprised between said loading and unloading position and said infusion dispensing position, said at least one guide further comprising a second portion that branches off from a first end of said first straight portion, said first end being adjacent to said front opening of said supporting element, said second portion being inclined with respect to said first straight portion away from said cartridge holder and comprising a first stroke limiter, which is adapted to stop said cartridge holder with respect to said supporting element in said position for loading and unloading said cartridges, said adapter further comprising means with manual activation for moving said cartridge holder with respect to said supporting element in order to move said cartridge holder and move said cartridges closer to dispensing means, said means comprise a movement ring, which is associated with said cartridge holder by means of a cam integral with the movement ring for the relative translational motion of said cartridge holder with respect to said movement ring along a rotational axis of the movement ring as a consequence of the relative rotation of said movement ring with respect to said cartridge holder around the rotational axis of the movement ring.
