  • Patent number: 11359740
    Abstract: An electromagnetic valve includes a sleeve having a valve hole at a central portion thereof, a spool, and an electromagnetic solenoid. The sleeve has plural ports penetrating the sleeve between inner and outer peripheral surfaces thereof and disposed side by side in a central axis direction of the valve hole. In the spool, plural lands having an outer peripheral surface facing an inner peripheral surface of the valve hole are provided side by side in the central axis direction. The electromagnetic solenoid is configured to move the spool in the central axis direction in the valve hole. The ports have one or plural recessed portions in which working oil is stored. When the spool is decentered with respect to the sleeve, a pressure of the working oil stored is increased.
