スプール弁。A spool for opening and closing an oil inlet or an oil outlet is slidably provided in a sliding hole formed in the body, and the spool is pressed in one direction by the force of a spring or pilot oil pressure, and a nozzle is attached to one end of the spool. a sealing wall is provided at one end of the sliding hole, the nozzle is passed through the sealing wall to form a control oil chamber between one end of the spool and the sealing wall, and the push rod of the proportional solenoid is provided with a sealing wall. A flapper attached and loaded with a spring is disposed to face the nozzle, a pilot oil supply port is provided in the body for supplying pilot oil to the control oil chamber, and an orifice is provided between the supply portion and the control oil chamber. A discharge port is provided in the body to allow pilot oil connected to the control oil chamber to flow out from between the nozzle and the flapper through the nozzle, and to discharge the leaked oil to a tank, and the spool is connected to the control oil chamber. A proportional solenoid type spool valve, characterized in that the valve is moved to follow the flapper.
