Abstract
A tank for compressed natural gas utilizes internal tension members. The tank has an upper half and a lower half, each half being formed with at least two cylindrical portions separated by a Y-shaped junction. The sections of each half have engagement members in the interiors. The engagement members include a head and a socket which slide longitudinally together to secure the upper and lower halves against tension due to the gas pressure.
Claims29
A tank for containing a gas, comprising in combination:
- a first section of wall having at least two parallel partially cylindrical portions integrally joined together at a first junction;
- a second section of wall having at least two parallel partially cylindrical portions integrally joined together at a second junction, the first and second sections being joined to each other to define a shell with an interior;
- tension means for resisting internal pressure tending to push the first and second junctions apart from each other, the tension means including engagement members formed selectively on interior surfaces of the junctions of the first and second sections for joining the first and second junctions to each other in the interior of the shell by sliding engagement;
- and
- front and rear covers joined to forward and rearward ends of the shell.

A tank for containing a gas, comprising in combination:
- a first section having an inner surface and an outer surface and at least two partially cylindrical portions which have parallel longitudinal axes and which are integrally joined together at a Y-shaped first junction;
- a longitudinally extending socket formed on the inner surface of the first section at the first junction;
- a second section having an inner surface and an outer surface and at least two partially cylindrical portions integrally joined together at a Y-shaped second junction;
