燃料噴射ポンプにおけるタイマピストン位置検出
機構。 This is a means for non-contact detection of the timer piston position of a fuel injection pump, in which a magnetic resistance element is mounted on the timer piston cover on the same axis as the timer piston, and a joint rod with a large lead female thread is attached to the timer piston. fixed,
The timer piston cover is provided with a bearing, which supports a shaft having a magnet at the tip facing the magnetic resistance element so as to only allow rotation, and the other end of the shaft has a male screw with a large lead that engages with the female screw. A timer piston position detection mechanism in a fuel injection pump, characterized in that the timer piston position detection mechanism is provided.
