Abstract
Safety device for a compressed gas tank comprising a membrane influenced by an elastic effort and resting simultaneously on two concentric seats. It is characterized in that the applying of the pressure to the seat having the smallest diameter corresponds to a sealing position and that the applying of the pressure to the seat having the greatest diameter causes a sudden opening of the device.
