FLAPPER TYPE AC SOLENOID AND SOLENOID VALVE

摘要

PURPOSE: To provide a low-cost small-sized flapper type AC solenoid capable of being manufactured relatively simply and having excellent durability and attraction force. ;CONSTITUTION: A core 25 for forming a flapper type AC solenoid 2 is formed of a shaft 28 and an attracting part 29 formed at the one end of the shaft 28. A winding 23 is wound on the outer periphery of the shaft 28. A flapper 19 is disposed at the position opposed to the attracting surface 29a of the part 29. An annular shading coil 30 is mounted in an annular mounting groove 31 as a mounting recess formed on the surface 29a. The area of the surface 29a is set larger than the sectional area of the shaft 28.;COPYRIGHT: (C)1996,JPO
