The invention relates to a fuel system (1, 1 ') for installation in a hydrogen-operated vehicle having a plurality of hydrogen pressure tanks which are designed to have a high-pressure level of at least 200 bar, said fuel system comprising the following structural units: a filler collar (2, 2') which is suitable for being connected to a corresponding coupling of a filling station, an intermediate piece (3) which is suitable for being connected to a corresponding coupling of a filling station, and a plurality of fuel tanks (4, 5 ') which are designed to have a high-pressure level of at least 200 bar. The invention relates to a hydrogen pressure tank (1), comprising:-a central part (2) having a housing (3a) and at least one check valve (7.1, 7.2),-a distributor (4) having a plurality of connections (13) for lines to the hydrogen pressure tank, and-a valve assembly (5) comprising at least one shut-off valve (22), a connection (23) for an output line and a pressure reducer (10), the pressure reducer is designed such that it can reduce the pressure of the hydrogen from a high pressure level in the pressure tank to a medium pressure level between 3 bar and 30 bar; wherein the intermediate piece (3) is connected on one side to the filler neck (2) and on the other side to the distributor (4), such that the flow path (100) during filling is substantially straight from the filler neck (3) through the intermediate piece (3) to the input into the distributor (4); and wherein the valve assembly (5) is connected to the intermediate part (3) without a line in the middle such that hydrogen can be conducted from the connection (13) for the line to the pressure tank through the pressure reducer (20.1, 20.2) to the connection (23) for the outlet line.

    用于装入在具有多个氢气压力罐的氢气运行的车辆中的燃料系统(1、1′),氢气压力罐被设计成具有至少为200巴的高压水平,其中,燃料系统包括以下结构单元:‑加注接套(2、2′),加注接套适用于与加注站的相应的耦接部连接,‑中间件(3),中间件具有壳体(3a)和至少一个止回阀(7.1、7.2),‑分配器(4),分配器具有多个用于通向氢气压力罐的线路的联接部(13),‑和阀结构单元(5),阀结构单元包括至少一个截止阀(22)、用于输出线路的联接部(23)和减压器(10),减压器被实施成使得其能够将氢气的压力从压力罐中的高压水平降低到3巴与30巴之间的中压水平;其中,中间件(3)在其中一侧与加注接套(2)连接,并在其中另一侧与分配器(4)连接,使得在加注时的流动路径(100)从加注接套(3)通过中间件(3)直到进入分配器(4)的输入端基本上是直的;并且其中,阀结构单元(5)在中间没有管线路的情况下与中间件(3)连接,使得氢气能够从用于通向压力罐的线路的联接部(13)穿过减压器(20.1、20.2)被导引至用于输出线路的联接部(23)。
