HALL TYPE POSITION SENSOR AND EXHAUST GAS RECIRCULATION VALVE COMPRISING THE SAME

摘要

PURPOSE: A hall type position sensor and an exhaust gas recirculation valve including the same are provided to obtain a linear output depending on a position change of a moving object, and to accurately control the position of a pintle shaft. CONSTITUTION: A hall type position sensor(160) comprises a first bar magnet(165), a second bar type magnets(175), and a hall element(185). The widths of the first and second bar magnets are getting narrow toward a second electrode, respectively. The first and the second bar magnets are arranged in parallel to be moved with a moving object. The hall element is fixed between the first and the second bar magnets. When the hall element is moved in a longitudinal direction of the moving object, the hall element provides a linear output.
