Embodiment Construction

[0025] see now especially figure 1 , one embodiment of the multi-chamber pressure vessel of the present invention is generally indicated by numeral 10 in the drawings. The pressure vessel 10 includes a multi-chamber vessel body (or body portion) 12 and sets of closure assemblies 14 . The main body portion 12 preferably has a substantially uniform cross-section with an inlet 15 therein.

[0026] Body portion 12 may be configured according to any design known to those skilled in the art. According to a preferred embodiment of the present invention, the main body portion 12 generally includes several arcuate outer wall portions 16 . The outer wall portion 16 is connected to an inner web portion 18 . In the described embodiment, the several cavities are each formed from a combination of at least one inner web portion and at least one arched outer wall portion. As is known in the art, the inner web portion 18 may have channels (not shown) shaped to penetrate the inner web port...

Abstract

Closure modules are coupled to and enclose ends of a multi-cell pressure vessel, especially a multi-cell pressure vessel having arcuate outer wall segments connected by internal web segments that define a plurality of cells in the pressure vessel. The closure modules each have an arcuate surface portion and at least one interfacing surface portion integrally connected at a marginal extent thereof with a marginal extent of the arcuate surface portion. The arcuate surface and interfacing surface portions define a closure module chamber and have peripheral edges. The arcuate surface portion of one of the closure modules abuts contiguously against an interfacing surface portion of an adjacent one of the closure modules. The closure modules are particularly useful for use with multi-cell tanks and vessel bodies, especially tanks and vessels suitable for storing liquid propane.

Description

technical field [0001] The present invention relates to the structure and construction of an end closure assembly which is combined with and closes a tank and container body. In particular, the present invention relates to the construction and construction of end closure assemblies for combination with and closure of multi-chambered tank and vessel bodies, particularly tanks and vessels for storing liquid propane. Background technique [0002] As we all know, pressure vessels are used to store liquids and gases under pressure. An ever-expanding use of pressure vessels is their use in motor vehicles such as automobiles to store alternative fuels such as propane and natural gas. There is a growing perception that alternative fuels are more beneficial than gasoline for motor vehicles. Accordingly, methods have been devised to convert gasoline-fueled vehicles to propane-fueled vehicles by converting gasoline-burning vehicles to use propane (or natural gas) instead of gasoline....
