ABSTRACT:
Device for controlling a flow limiting valve mounted in a cover of an appliance for cooking under pressure, the appliance further including a container to be closed by the cover, the cover having a central axis and the valve being movable between an open position for permitting flow of fluid out of the appliance and a closed position for blocking flow of fluid out of the appliance, the device comprising a cover handle and a bolt mounted in the cover handle for movement between first and second end positions along a line passing through the central axis, the bolt being operatively associated with the valve for permitting free displacement of the valve when the bolt is in the first end position and for preventing the valve from moving to the closed position when the bolt is in the second end position, and wherein: the bolt comprise biasing for elastically urging the bolt toward the first end position; and the device further comprises defining an automatic locking-unlocking system coupled with the bolt for controlling movement of the bolt between the first and second end positions, the system having a first state for locking the bolt in the second end position and a second state for automatically unlocking the bolt when the cover is brought into a position to close the container.
