。 The valve body has two ports each communicating with two channels through which high-pressure fluid and low-pressure fluid selectively flow, and has an inner hole through which these two ports open, and can slide into this inner hole. a cylindrical spool that is fitted into the spool and has a bypass slit cut out in the radial direction at one end that connects the two ports; a spring that biases the spool in a direction that closes communication between the two ports; In the electromagnetic control valve, the solenoid is provided with a solenoid to which a control current is applied depending on the vehicle speed, etc., and which sucks the spool in a direction in which two ports communicate with each other according to the control current. An electromagnetic control valve comprising a pressure introduction hole provided in either or both of the valve body and the spool.
