MULTIPLE-CAVITY HIGH-PRESSURE CYLINDER Russian patent published in 2012 - IPC F17C1/00 

FIELD: machine building.

SUBSTANCE: multiple-cavity high-pressure cylinder includes housing consisting of cylindrical part and two semi-spherical bottoms with h thickness. Inside the housing there arranged are i=0, 1, 2, n spherical closed covers forming spherical cavities and two semi-spheres of the same thickness, which together with semi-spherical bottoms form extreme spherical cavities one of which is connected to filling device. All spherical cavities are connected to each other by means of tubular channels and form the first isolated number of interconnected spherical cavities. Centres of spheres are located on housing axis. Cavities formed with cylindrical part of housing and external surfaces of spherical covers form other non-spherical system of cavities. Each non-spherical cavity is partitioned with a belt (1/4)h thick with the centre located along cylinder axis in the middle between spherical covers, thus forming in the cylinder the second and the third isolated system of cavities; at that, the second one is formed with a number of cavities each of which is restricted with belt wall and walls of segments of neighbouring spherical covers (1/2)h thick, which are restricted with belts. The third number is formed with pairs of identical cavities formed with cylindrical part of housing (1/2)h thick, wall of belt and part of spherical cover (3/4)h thick, which is located between neighbouring belts. All elements of cylinder are made of coaxial covers of single average radius R. The second and the third isolated systems of interconnected cavities are connected to filling device.

EFFECT: possibility of wide variation of overall dimensions is provided so that numerical value of that ratio is maintained, and values of resistance to cyclic loads are increased.
