摘要： An electromagnetic control valve is composed of a spool section for switching fluid passages on or off, a solenoid section for driving the spool in one direction, a magnetic moving core slidably disposed in the stator, a nonmagnetic shaft fixed to the moving core, and a spring member for biasing the spool in the direction opposite to the one direction. The spool section includes a spool and a sleeve. The solenoid section is connected to the spool section and includes a cylindrical magnetic stator, cylindrical magnetic yoke disposed to surround the stator and a magnetic coil disposed between the stator and the yoke. The stator is fixed to the sleeve at one end and having a bottom at the other end thereof. The shaft has one end to be in contact with the end of the sleeve thereby positioning the moving core in a longitudinal direction in the stator.
