<p>A safety valve (10) of a boiler (12) of a device (14) for making hot beverages, particularly coffee, comprises an intermediate valve body (18a), a plug (22) and resilient means (23) inserted into the seat (20) of the intermediate valve body (18a). The intermediate valve body (18a) comprises a peripheral wall (28) designed to be folded over to define a reaction portion of the resilient means (23) and positively press the plug (22), obtaining a final valve body (18). The peripheral wall (28) partly closes off a first opening (24) of the intermediate valve body (18a) and the plug (22) partly projects from the final valve body (18).</p> |
