Pressure vessel for storing gases or liquids under pressures above 200 bar

摘要

Pressure vessel for storing gases or liquids under pressures above 200 bar, with an elongated storage element (1) comprising: - at least one rotationally symmetrical, preferably conical and / or cylindrical, middle section (2), - a plurality (N) or number (N ) of individual layers (n = 1 to N) each having at least one braided or wound reinforcing fiber (7, 7 '), preferably at least two braided or wound reinforcing fibers (7, 7'), wherein the individual layers (n = 1 to N ) in a local sequence along a vertical (S) to the rotation axis (11) of the central portion (2) are superimposed, and wherein an inner starting position (n = 1) surrounds a hollow body (4) arranged within the storage element or forms said hollow body, and wherein a top layer (n = N) disposed above the initial layer (n = 1) is provided, and wherein the reinforcing fiber (7, 7 ') or the reinforcing fiber n (7, 7 ') in each of the individual layers (n = 1 to N) has or have a position-dependent fiber angle φn relative to the rotational axis (11') projected into the respective individual layer (n = 1 to N), characterized in that starting from the initial position (n = 1) to the final position (n = N) the angular differences Δφn of the fiber angles φn of two successive individual layers (n = 1 to N-1) is defined by the equation Δφn = φn + 1-φn n = 1 to N-1, and for at least 80%, preferably at least 90%, of all angular differences Δφ1 to ΔφN-1, the condition Δφn ≥ 0 is satisfied.
