    • The invention discloses a pole tube (1) and a solenoid actuator provided therewith, having an intermediate piece (4) to which a pole piece (2) and a tube piece (6) are attached, which together delimit an accommodating area (8) for an armature (10) of the solenoid actuator. According to the invention, the geometry of the end-face regions, which are connected by means of welding, of the intermediate piece and the tube piece and the pole piece is selected such that, taking into consideration the melting points of the materials used, the electrical resistance of the joining partners in the joining region is essentially the same, with the result that, in the case of resistance welding, the heat input to both joining partners is approximately the same.
    • 一种螺线管致动器的极管,包括具有第一中间端面和第二中间端面的非磁性中间件,具有构造成在第一接合区域处连接第一中间端面的极端面的极靴,以及 管件,其具有构造成在第二连接区域处连接第二中间端面的管端面。 中间件,极靴和管件中的至少两个被构造为可以使用电熔接彼此连接。 中间件,极靴和管件中的至少两个具有不同的导电性。 设置在对应的第一和第二接合区域中的极管和管件的相应部分被构造成各自具有基本上等于中间件的一部分的电阻的电阻。

    • Magnet armature construction having a ferromagnetic body and an elastomer sealing element. The ferromagnetic body is preferably a cylindrical body, having a lateral surface and two head ends. At least one of the head ends is provided with at least one seat having a bottom surface and a circumferential wall. This seat is shaped in such a manner that a positively locking anchoring with the sealing element is obtained by one or more positively locking geometric formations being provided in the circumferential wall of the seat. The elastomer sealing element is injection-moulded into this seat. The positively locking anchoring is also effected by at least one cavity being provided in the ferromagnetic body, through the bottom of the seat. The circumferential wall of this cavity is provided with at least one positively locking geometric formation. A part of the elastomer sealing element is injection-moulded into this cavity.
    • 具有铁磁体和弹性体密封元件的磁体电枢结构。 铁磁体优选为具有侧面和两个头端的筒状体。 头端中的至少一个设置有至少一个具有底表面和周壁的座。 这种座椅的形状是这样一种方式,即通过设置在座椅的周向壁上的一个或多个正向锁定的几何形状来获得与密封元件的正向锁定锚固。 弹性体密封元件注塑成型。 正向锁定锚固还通过至少一个空腔设置在铁磁体中,通过座的底部来实现。 该空腔的圆周壁具有至少一个正向锁定几何形状。 弹性体密封元件的一部分被注塑成型腔。
