摘要:【中文】一种用于发动机(100)的燃料喷射器组件(140)的管道结构(144)包括第一环形结构(170)、多个管道(146)、多个柱(172),和接合结构(200)。燃料喷射器组件(140)包括具有排出燃料的多个孔口(154)的燃料喷射器(142)。第一环形结构(170)被构造成联接到发动机(100)的气缸盖(106),并且限定中心轴线(174)。多个管道(146)围绕中心轴线(174)圆形地排列,并且构造成给燃料喷射器(142)排出的燃料提供通道(204)。多个柱(172)将多个管道(146)连接到第一环形结构(170)。此外,接合结构(200)构造成与燃料喷射器(142)接合以使多个管道(146)与多个孔口(154)对准,使得多个管道(146)中的每一个构造成接收从多个孔口(154)中的相应一个孔口排出的燃料。 【EN】A conduit structure (144) for a fuel injector assembly (140) of an engine (100) includes a first annular structure (170), a plurality of conduits (146), a plurality of posts (172), and an engagement structure (200). The fuel injector assembly (140) includes a fuel injector (142) having a plurality of orifices (154) that discharge fuel. The first annular structure (170) is configured to be coupled to a cylinder head (106) of an engine (100) and defines a central axis (174). The plurality of conduits (146) are circularly arrayed about a central axis (174) and are configured to provide a passage (204) for fuel discharged by the fuel injector (142). A plurality of posts (172) connect the plurality of conduits (146) to the first ring structure (170). Further, the engagement structure (200) is configured to engage with the fuel injector (142) to align the plurality of conduits (146) with the plurality of orifices (154) such that each of the plurality of conduits (146) is configured to receive fuel discharged from a respective one of the plurality of orifices (154).

摘要:【中文】为了提供一种改进的无真空助力器的制动设备(1),其中缸活塞(3)的零点尽可能始终保持在规定的窄公差范围内并同时可靠地减小止挡噪音,根据本发明提出,止挡盘(5)能沿轴向方向在限定的压缩行程(S)上弹性可逆地被压缩并具有用于以行程受控制地限定的方式限制压缩行程(S)的装置。 【EN】In order to provide an improved brake system (1) without a vacuum booster, in which the zero point of the cylinder piston (3) is kept as always as possible within a defined narrow tolerance range and at the same time the blocking noise is reliably reduced, it is proposed according to the invention that the blocking disk (5) can be compressed in the axial direction in an elastically reversible manner over a defined compression stroke (S) and has means for limiting the compression stroke (S) in a stroke-controlled defined manner.
