弁。[Claims for Utility Model Registration] A spool is slidably and substantially liquid-tightly fitted into a valve hole in a housing having a high-pressure port, a low-pressure port, and a control pressure port; While a control force is applied, the distal end surface of the reaction rod extending in the axial direction from one end surface of the spool is exposed to the outside of the valve hole, thereby changing the cross-sectional area of the reaction rod and the valve. A fluid reaction force having a magnitude equal to the fluid pressure in the hole is applied to the valve spool, and the valve spool is moved based on the fluid reaction force and the control force, so that the control pressure port is connected to the high pressure In the spool-type electromagnetic pressure control valve, the fluid pressure of the control pressure port is controlled to a height corresponding to the magnitude of the excitation current of the solenoid by selectively communicating between the reaction port and the low pressure port. The rod is separate from the spool body, is movable relative to the spool body in the radial direction, and is connected to the spool body in an axial direction so that it cannot be separated beyond a certain limit, and A metal-to-metal seal is formed to prevent fluid from leaking from the valve hole by reducing the clearance between the outer peripheral surface of the rod and the inner peripheral surface of the reaction rod hole formed in the housing. Spool type electromagnetic pressure control valve.
