Abstract
A pressure vessel formed by either by: a) mating a first end or closure to a second end or closure or b) mating a first end to an intermediate body member and mating the intermediate body member to a second end; the first end comprising a hollowed thin walled dome (14) having an exterior surface (15a) and an interior surface (15b) and the dome terminating in an edge surface (14a), the dome (14) having an axis Y extending through its geometric center of the exterior surface, the dome supporting at least one thin hollow walled projection (16, 18, 20) having an exterior (19a) and interior surface (19b), the at least one projection extending outwardly from the dome outer surface (15a), and terminating in a top surface (16a, 23).
Claims16
A pressure vessel comprising a first end portion and a second end portion, the first end portion comprising:
- a dome having an exterior surface and an interior surface, the dome including a first projection having an exterior and interior surface, the first projection extending outwardly from the dome exterior surface and comprising an end surface,
- wherein the end surface of the first projection defines an opening, wherein a control element is coupled to the opening to achieve a gas tight configuration, wherein the control element is an ignitor;
- wherein the dome further comprises a second projection and a third projection, each comprising an end surface;
- and
- wherein the end surface of the second projection defines an opening and a ball is welded to the opening of the second projection to seal the opening.
