Beschreibung
Zusammenfassung:	PURPOSE: A valve opening degree detecting apparatus is provided to simplify mechanical structure by omitting a high-low limit switch. CONSTITUTION: A valve opening degree detecting apparatus comprises cases(110,120), a shaft(190), a main gear(140), a potentiometer(150), and a control part. The space is formed inside the case. The shaft passes through the case and is exposed in the space. The shaft operates the valve due to rotation. The main gear is installed inside the case. The main gear is coupled on the shaft around the shaft. The potentiometer comprises a meter gear(151) which is installed in order to engage with the main gear and rotate.
