Patent number: 9995407Abstract: 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.Type: GrantFiled: September 15, 2015Date of Patent: June 12, 2018Assignees: WESTPORT POWER INC., EMER, S.P.A.Inventors: Giulia Omesti, Roberto Defilippi, Soroush Farzin, Giulio Brizzolari

Patent number: 9562618Abstract: 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.Type: GrantFiled: January 27, 2015Date of Patent: February 7, 2017Assignee: Emer S.p.A.Inventors: Paulo Peli, Giorgio de Ruggieri, Roberto Defilippi
