Arrangement having a plunger piston arranged in a guide in a housing cover, and use thereof in a pneumatic braking-value sensor

The invention relates to an arrangement having a plunger piston (20) which is arranged in a guide (14, 25) in a housing cover (6) and which acts via a pressure plate (5) and a pressure spring (4) on apiston (3) guided in a housing (2). To simplify the production of an arrangement of said type, it is provided that the housing cover (6) is screwed to the housing (2), that the housing cover (6) is composed of a dimensionally rigid material which can be cast into the installation dimensions, that the guide (14, 25) is composed of a dimensionally rigid material which can be cast into the installation dimensions and which exhibits good sliding characteristics, and that the guide (14, 25) is screwed or clipped to the housing cover (6). 本发明涉及种具有布置在壳体盖(6)中的引导件(14、25)中的冲顶活塞(20)的装置，该冲顶活塞通过压板(5)和压缩弹簧(4)作用于在壳体(2)中引导的活塞(3)。为了简化这种装置的制造而设置：壳体盖(6)与壳体(2)螺接，壳体盖(6)由能够按安装尺寸铸造的、形状稳定的材料组成，引导件由具有良好滑动特性的、能够按安装尺寸铸造的、形状稳定的材料组成，并且引导件(14、25)与壳体盖(6)螺接或卡接。
