Abstract
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.

Method for the manufacture of a safety valve of a boiler of a device for making hot beverages, particularly coffee, comprising the stages of:
- manufacturing an intermediate valve body defining a seat designed to receive a plug and opening towards the exterior of the valve body through a first opening and a second opening, the said valve body comprising at least one peripheral wall located close to the said first opening,
- inserting the plug into the seat of the intermediate valve body,
- inserting resilient means into the seat of the intermediate valve body,
- subsequently folding over the said at least one peripheral wall to define a reaction portion of the resilient means and positively pressing the said plug against the said second opening of the said valve body, obtaining a final valve body.
Intermediate valve body of a safety valve of a boiler of a device for making hot beverages, in particular coffee, the said intermediate valve body comprising a seat designed to receive a plug and open towards the exterior through a first opening and a second opening, the said intermediate valve body also comprising at least one peripheral wall located close to the said first opening and designed to be folded over to define a reaction portion of the said resilient means of the said safety valve and to positively press the said plug against the said second opening of the said valve body to obtain a final valve body.
