Abstract
A starting device for a chemical oxygen generator comprises a casing which has a chemical oxygen generating material therein and with a first wall above the material with an opening bounded by an annular sealing face and an opposite second wall below the oxygen generating material with at least one passage for the passage therethrough of an oxygen which is generated. A liquid ampule is disposed above the oxygen generating material and a thrust bolt is mounted in the opening of the casing over the liquid ampule and is movable when actuated from a starting position overlying and spaced from the ampule to an actuated position in which it penetrates and breaks the ampule. The coil spring is associated with the bolt and it biases the bolt in a direction toward the ampule. A sealing ring is disposed around the bolt and is located initially above the opening and moves with the bolt to engage into the opening and seal the top of the container when the bolt is in the actuated position.
