渦によつて該渦発生体の下流側に発生する圧力変
化に基いて流量を検出する圧力変化形カルマン渦
式エアフローセンサにおいて、前記渦発生体の下
流に設定された２個の導圧孔を、ダイヤフラムに
よつて２分され、かつ密閉された２つの導圧室に
連通するとともに、一方の導圧室には電極を設定
し、ダイヤフラム側には両導圧室の圧力変化に基
くダイヤフラムの振動によつて前記電極に対して
接離する接点を設けた圧力変化検出形カルマン渦
式エアフローセンサ。 In a pressure variable Karman vortex air flow sensor that detects a flow rate based on a pressure change generated downstream of the vortex generator by a Karman vortex generated by the vortex generator placed in a flow path, Two pressure-conduction holes set downstream are connected to two pressure-conduction chambers that are divided into two and sealed by a diaphragm, and an electrode is set in one of the pressure-conduction chambers, and an electrode is set on the diaphragm side. This is a pressure change detection type Karman vortex air flow sensor which is provided with a contact point that comes into contact with and separates from the electrode by vibration of a diaphragm based on pressure changes in both pressure chambers.
