    摘要： A self-adjusting engine timing pickup probe adapted to be received in a tubular engine mounting bracket, the probe extending into close proximity with a position indicator on a rotating engine part to provide an air gap. An elongated sensor assembly extends through the tubular member and has relative axial movement therewith for initial manual adjustment of the sensor assembly to provide an effective air gap. Interference means are provided between the tubular member and the sensor assembly, the interference means establishing substantial resistance to relative axial movement between the tubular member and the sensor assembly. The tubular member has a spring means which engages the engine mounting bracket and holds the two together in a yielding manner. The spring means urges the tubular member and associated sensor assembly inwardly toward the rotating engine part. However, during engine operation, the rotating engine part, due to tolerances, wear, vibrations, etc., engages the sensor assembly and tends to move both the sensor assembly and the tubular member outwardly of the mounting bracket. In so doing, the spring means holding the tubular member in the engine mounting bracket yields, while the interference means between the tubular member and the sensor assembly does not yield. Thus, the engagement between the sensor assembly and the rotating engine part does not cause relative axial movement between the tubular member and the sensor assembly.

    摘要翻译： 一种自适应引擎定时拾取探头，其适于容纳在管状发动机安装支架中，探头与旋转的发动机部件上的位置指示器紧密接近以提供气隙。 细长的传感器组件延伸穿过管状构件并且具有相对的轴向运动，用于传感器组件的初始手动调节以提供有效的气隙。 干涉装置设置在管状构件和传感器组件之间，干涉装置建立了对管状构件和传感器组件之间的相对轴向运动的实质阻力。 管状构件具有弹簧装置，该弹簧装置接合发动机安装支架并以屈服的方式将两者保持在一起。 弹簧装置将管状构件和相关联的传感器组件向内推向旋转的发动机部件。 然而，在发动机操作期间，旋转的发动机部分由于公差，磨损，振动等而接合传感器组件，并且倾向于将传感器组件和管状构件两者移动到安装支架的外部。 在这样做时，将管状部件保持在发动机安装支架中的弹簧装置产生，同时管状部件和传感器组件之间的干涉装置不产生。 因此，传感器组件和旋转的发动机部件之间的接合不会导致管状部件和传感器组件之间的相对轴向运动。

    摘要： The probe includes a tubular housing having a first portion and a second portion. The first portion is adapted to be mounted in place of the glow plug of a selected engine cylinder. A light pipe within the first portion directs light from the combustion zone to a phototransistor within the second portion. The front of the first portion has a reduced size aperture defined by an internal shoulder against which the front of the light pipe is seated. The rear of the first portion carries resilient sealing means which is deformed when the second portion is telescoped thereon so as to provide a detachable, frictional, light-tight thermally insulated connection therebetween. A phototransistor is mounted within the second portion to convert light passing through the light pipe into electrical signals. A cable carries these electrical signals to processing equipment. A base resistor is located in the second portion between the base of the phototransistor and the cable. The part of the first portion that projects from the engine is short with respect to the part that fits into the engine. The projecting portion carries wrench-engaging bosses.
