带有排放管道的线轴
摘要：
带有排放管道的线轴，发明内容的摘要。一种电磁致动器(30)的线轴组件(44)，所述电磁致动器适于位于燃料喷射器(5)中，所述线轴组件(44)包括：‑芯(93)，该芯沿着主轴线延伸；‑线圈(92)，该线圈围绕所述芯(93)布置，所述线圈被包覆成型，使得所述线圈具有从第一表面(104)轴向延伸到第二表面的柱形外表面(108)；以及‑轴向盲孔(43)，该轴向盲孔在所述线轴组件(44)内轴向向内地从所述第一表面(104)延伸到远端(106)，所述轴向盲孔(43)适于容纳用于偏置磁性电枢的弹簧；其特征在于：所述线轴组件(44)还设置有排放管道(42)，所述排放管道从所述轴向盲孔(43)穿过包覆成型件(96)延伸到所述柱形外表面(108)。
摘要（英）：

Bobbin with venting conduit abstract of the disclosure Bobbin assembly (44) of an electromagnetic actuator (30), adapted to be in a fuel injector (5), the bobbin assembly (44) comprising: -a core (93) extending along a main axis -a wire coil (92) arranged around the core (93), the coil being over-moulded so that it has a cylindrical external surface (108) extending axially from a first surface (104) to a second surface and, -an axial blind bore (43) extending axially and inwardly inside the bobbin assembly (44) from the first surface (104) to the distal end (106), the blind bore (43) adapted to accommodate a spring (33) for biasing a magnetic armature; characterizedin that: the bobbin assembly (44) is further provided with a venting conduit (42) extending through the over-moulding (96) from the blind axial bore (43) to the external cylindrical surface (108).
