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.

[ I claim:] [1.] 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; andfront and rear covers joined to forward and rearward ends of the shell. [9.] The tank according to claim 1, wherein:the tension means defines separate first and second chambers in the tank; and the tank further comprises:check valve means for allowing free flow of gas from the first chamber to the second chamber during filling of the first chamber, but prevents free flow of gas through the check valve means from the second chamber to the first chamber; and whereinthe tension means has clearances therein which allow gas flow from the second chamber to the first chamber at a lesser rate than the rate occurring through the check valve means during filling of the first chamber. substantially cylindrical chambers separated by the engaging head and socket. 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;a longitudinally extending head formed on the inner surface of the second section at the second junction which mates with the socket to internally join the first and second junctions to each other to resist internal pressure tending to push the first and second junctions apart from each other; andthe first and second sections having side edges which are joined to each other, and front and rear covers joined to forward and rearward ends of the first and second sections, defining a shell with at least two substantially cylindrical chambers separated by the engaging head and socket. The tank according to claim 10, wherein:the first section, including the head, is an extruded member; andthe second section, including the socket, is an extruded member. The tank according to claim 10, wherein each of the covers has at least two spherical portions, one for each of the chambers. The tank according to claim 10 wherein the side edges of the first and second sections are joined to each other by welding, and the covers are joined to the first and second sections by welding. The tank according to claim 10, further comprising:check valve means for allowing free flow of gas from a first one of the chambers to a second one of the chambers during filling of the first one of the chambers, but preventing free flow of gas through the check valve means from the second one of the chambers to the first one of the chambers; and whereinthe mating head and socket have clearances therein which allow gas flow from the second one of the chambers to the first one of the chambers at a lesser rate than the rate occurring through the check valve means during filling of the first one of the chambers. A tank for containing a gas, comprising in combination:a shell having first and second sections, each of the sections being an extrusion having at least two partially cylindrical portions having parallel longitudinal axes and integrally joined together at a Y-shaped junction, the first and second sections being joined to each other;each of the sections having an outer surface and an inner surface;a longitudinally extending engagement member located on the inner surface at the junction of each of the sections;a tension member insertable into the shell during assembly, having first and second edges, each edge having an engagement member which slidably engages the engagement members of the junctions of the first and second sections, to resist internal pressure tending to push the first and second sections apart from each other; andfront and rear covers joined to forward and rearward ends of the shell. The tank according to claim 15, wherein the engagement members comprise mating head and socket members. The tank according to claim 15, wherein the tension member comprises a flat partition. A tank for containing a gas, comprising in combination:upper and lower sections and right and left side sections, each of the sections being an extrusion having at least two partially cylindrical portions having longitudinal parallel axes and integrally joined together at a Y-shaped junction, the upper and lower sections being joined to each other by the right and left side sections, defining a shell having at least four parallel axes;each of the sections having an outer surface and an inner surface;a longitudinally extending engagement member on the inner surface at the junction of each of the sections;a vertical tension member having upper and lower edges, each edge having an engagement member which slidably engages the engagement members of the junctions of the upper and lower sections to resist internal pressure tending to push the upper and lower sections apart from each other;a horizontal tension member having right and left edges, each edge of the horizontal tension member having an engagement member which slidably engages the engagement members of the junctions of the right and left side sections to resist internal pressure tending to push the right and left side sections apart from each other; andfront and rear covers joined to forward and rearward ends of the shell. The tank according to claim 18, wherein the engagement members comprise mating head and socket members.
