All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Machine operating with capsules for the preparation of coffee and other hot beverages, comprising an inner compartment for housing a capsule during use, a lever hinged to the machine about a fulcrum for pushing the capsule into the compartment, closing means for enclosing the capsule inside an infusion chamber defined by a pair of oppositely arranged members and piercing the capsule on opposite sides, and circulation means for circulating a flow of hot pressurized water through the capsule inside the infusion chamber; the machine being characterized in that it is designed to be equipped selectively with a first motorized actuator module, which comprises a support and a first electro-mechanical locking assembly mounted on the support so as to form a preassembled interchangeable module, and with a second manually operated actuator module, which comprises a second mechanical locking assembly able to be releasably connected to a lever which can be operated by a user so as to be manually actuated by means of the lever,
wherein the mechanical locking assembly comprises a toggle mechanism configured to connect the lever to a thrust member and move the thrust member in a substantially straight sliding direction (S), and
wherein the toggle mechanism comprises at least one tie-bar, an arm and a rod; the tie-bar being hinged with the thrust member and with an articulation; the arm being hinged with the articulation and with the machine; the rod being hinged with the articulation and with the lever.
2. Machine according to claim 1, wherein the first actuator module is removably housed inside an inner receiving seat of the machine and is fixed to the machine by means of releasable fixing members so as to be removable from the receiving seat and replaced with a second manually operated actuator module.
3. Machine according to claim 1, wherein the first electro-mechanical locking assembly is connected to a first one of said members so as to move it towards the other member in an essentially straight sliding direction (S).
4. Machine according to claim 1, wherein the locking assembly comprises a gear motor and a connecting-rod and crank mechanism driven by the gear motor and connected to a thrust member by means of a joint, for displacing the thrust member in the sliding direction (S).
5. Machine according to claim 4, wherein the locking assembly comprises a crank connected to a shaft of the gear motor and to a connecting-rod hinged with the joint of the thrust member, the thrust member being mounted slidably in the sliding direction (S) inside a guide.
