Abstract: A safety device for a cylinder holding gaseous fluids under pressure is disclosed. The safety device has a device body in which a passage is defined for a fluid; the passage extends from an entry aperture, suitable for being placed in fluidic communication with a cylinder, to an exit aperture. An obturator air tightly engages the passage, the obturator is movable from a first position, in which it indicates the presence of fluid at a pressure below a first predefined pressure threshold value, inside the cylinder, and a second position, in which it indicates the presence of fluid at a pressure above the first predefined pressure threshold value inside the cylinder. At least one temperature and/or pressure-sensitive relief device is positioned in the obturator in such a way that, upon exceeding a predefined temperature threshold or upon exceeding a second predefined pressure threshold, the relief device opens the passage for the fluid and permits the flow of fluid from the entry aperture towards the exit aperture.

Abstract: A coupling device comprises a body in which a passageway is formed which extends from an end aperture of such body to receive a pipe. A collar is positioned partially within the passageway to allow axial translation and has an annular flange outside the end aperture and flexible arms which extend in the passageway. The coupling device further comprises a safety mechanism having a cylindrical portion capable of being fitted on the portion of pipe straddling the end aperture so as to position the cylindrical portion between the pipe and the collar. The safety mechanism also has a safety fork connected to the cylindrical portion and which accommodates positioning of the collar between the body and the annular flange of the collar to inhibit axial movement of the collar towards the body of the device.

Abstract: A device has a body made of a first material, for example aluminum, and a component coupled to the body and made of a second material different from the first. The device further includes, between the body and the component, a spacer element of annular shape arranged around the component so as to be in contact on the one hand against the body and on the other against an abutment surface of such component, preventing, or at least reducing, direct contact between the component and the body. In some embodiments, the spacer element is made of a third material having an electric potential value between the first two materials.

Abstract: A thermal safety device includes a device body with an inlet duct and at least one outlet hole in communication with the atmosphere, a shut-off device mounted in the device body and movable between a closed position and an open position, and a retaining element that keeps the shut-off device in the closed position. The retaining element includes a casing containing a heat sensitive substance configured to expand upon reaching a first predetermined temperature and break the casing and allow the valve to open. A yielding support element provides support for and protects the casing until the temperature reached by the support element is higher than a second predetermined temperature which is higher than the first. The support element is configured to yield upon reaching the second predetermined temperature to place the shut-off device in the open position.
