摘要： The invention relates to a method for producing a pressure accumulator (1), in particular for storing hydrogen in motor vehicles. First, a pressure accumulator liner (3) which has at least one pole cap (2, 2′) is produced preferably by means of a plastic blow molding method, and the outside of the liner (3) is then provided, preferably braided, with a multi-ply reinforcing layer (9), which has reinforcing fibers (8). According to the invention, a fiber supply cap (10, 10′) is applied on the pole cap (2, 2′) prior to applying the reinforcing fibers (8), the outer surface of the fiber supply cap being spaced from the pole region (21, 21′) of the pole cap (2, 2′). The reinforcing fibers (8) are applied onto the body of the liner (3) and in the pole region (21, 21′) so as to correspond to the outer surface of the fiber supply cap (10, 10′) while the reinforcing layer (9) is applied such that the inner reinforcing layer (9) plies which are formed by the reinforcing fibers (8) are provided with a fiber supply (22) in the pole region (21, 21′) on the basis of the distance between the outer surface of the fiber supply cap (10, 10′) and the pole region (21, 21′) of the pole cap (2, 2′). The invention also relates to a pressure accumulator (1) produced in a corresponding manner.

摘要： The present invention relates to a pressure container for storing gases or liquids under pressures above 200 bar, comprising an elongate storage element having at least one rotationally symmetrical, preferably conical and/or cylindrical, central portion, a plurality (N) or number (N) of individual layers (n=1 to N) which each have at least one braided or wound reinforcing fibre, preferably at least two braided or wound reinforcing fibres, wherein the individual layers (n=1 to N) lie over one another in a local sequence along a perpendicular (S) to the axis of rotation of the central portion, and wherein an inner starting layer (n=1) surrounds a hollow body arranged within the storage element or forms said hollow body, and wherein an end layer (n=N) arranged above the starting layer (n=1) is provided, and wherein the reinforcing fibre or the reinforcing fibres in each of the individual layers (n=1 to N) has or have a layer-dependent fibre angle φn relative to the axis of rotation projected into the respective individual layer (n=1 to N), wherein, proceeding from the starting layer (n=1) to the end layer (n=N), the angle differences Δφn of the fibre angles φn of two successive individual layers (n=1 to N−1) are defined by the equation Δφn=φn+1−φn, where n=1 to N−1, and, for at least 80%, preferably at least 90%, of all angle differences Δφ1 to ΔφN−1, the condition Δφn≥0 is met.
