Method for making a safety valve of a boiler of a device for making a hot beverage, particularly coffee, and safety valve

摘要

A safety valve of a boiler of a device for making hot beverages, particularly coffee, comprises an intermediate valve body, a plug and resilient means inserted into the seat of the intermediate valve body. The intermediate valve body comprises a peripheral wall designed to be folded over to define a reaction portion of the resilient means and positively press the plug, obtaining a final valve body. The peripheral wall partly closes off a first opening of the intermediate valve body and the plug partly projects from the final valve body.
