Abstract

Valve pressure sensor and safety for pots, which being intended for application in pressure cookers, in order to detect an initial pressure when heating occurs inside the pot, and a rear opening to permit the release of steam when produced in heating a pressure above the operating, comprising a mounted mechanism between a valve body, associable to the corresponding hole in the lid of the pot, and an upper nut fixed to said body, the mechanism is constituted from a housed axially between the valve body and nut, with its ends located in holes in the opposing bases of said body and nut, with the particularity that in this bushing is mounted displaceably character freely cap a bolt longer than the cap, with its lower end provided with an O-ring in the rest position is separated from lower end cap, while heating and start of steam inside the pot upward movement of the pin occurs and the O-ring pressing thereof against the lower end cap, sealing the passage; further characterized in that the sleeve has an annular and intermediate under which is established a second O-ring seal bearing against an annular, internal of the valve body, sealing the outlet to the outside, the cap pushed constantly being toward said position a shoulder closing by a spring, which force is overcome by a pressure above the operating of the pot, in order to displace axially the sleeve, separating the O-ring with respect to the internal shoulder of the valve body, allowing passage of steam from inside the cooker to the outside.
