Patent ID: 8794478

Claim:
A pressure tank group comprising a plurality of pressure tanks for holding a pressurized fluid, each pressure tank comprising a hollow body which defines a storage space for the fluid, and a composite fiber material surrounding the hollow body which comprises one or more elements of a textile sheet material, wherein each pressure tank extends in a longitudinal direction and has a cross-sectional circumference defining an outer contour of the pressure tank, and wherein the plurality of pressure tanks are arranged in rows and columns in a plane extending perpendicularly to the longitudinal direction, wherein the outer contours of the pressure tanks in the regions which face neighboring pressure tanks are substantially flat, and wherein the pressure tanks are connected to one another by a winding of a reinforcing fiber, wherein the winding runs in at least one plane extending perpendicularly to the longitudinal direction and the reinforcing fiber surrounds each pressure tank along its entire cross-sectional circumference, so that a force which is exerted by the pressurized fluid onto the walls of each pressure tank can be distributed by the winding over all pressure tanks in the group.
