This spool 2 is connected by a spring 3 to an inlet port 4 and an outlet boat 5.
The rod 8 provided on the plunger 7 of the proportional solenoid 6 pushes the spool 2 in a direction that communicates the inlet port 4 and the outlet boat 5, and the diameter d1 of one end of the spool 2 is changed to the other end. The outlet pressure P is made larger than the side diameter d2.
. A rightward force is applied to the spool 2, that is, a force in a direction that blocks the inlet port 4 and the outlet port 5, so that a pressure proportional to the thrust of the proportional solenoid 6 is obtained.

Since the spool 2 is pushed with a thrust force of Not only does this require a large number of parts, resulting in high costs, but the contact surface between the rod 8 and spool 2 may become dented or worn, resulting in poor durability, and the rod 8 may sink into the plunger 7 or be removed. Furthermore, since the plunger 7 and rod 8 push the spool 2, they tend to buckle instead of being aligned in a straight line, generating lateral force and increasing hysteresis.

。The sleeve 12 is fitted flush with the body 10 and is prevented from being removed by a ring 17. The sleeve 12 is formed with an inlet port 18 and one outlet port. 19 communicates with an inlet hole 20° and an outlet hole 21 formed in the body 10. In other words, as shown in FIG.
A is formed, and the inlet/outlet boats 18, 1.9 are open to the smooth parts 12a, 12a on two outer peripheries, and form an inlet hole 20 and an outlet hole 21 between them and the hole 22 of the body 10. .

。The outer diameter d1 on one end of the plunger 15 is the outer diameter d2 on the other end.
The plunger 15 becomes larger due to the outlet side pressure.
is designed so that a force acts in a direction that blocks the inlet hole 18 and the outlet hole 19, and thereby the thrust of the proportional solenoid 6, that is, the electromagnetic force that produces the outlet side pressure proportional to the amount of current (current) applied to the coil 14. It constitutes a proportional pressure control valve.

か凹んだり、すりへったすせずに耐久性が向上する。By sliding the plunger 15 using the thrust and spring force of the proportional solenoid, the outlet pressure can be controlled in proportion to the amount of current flowing to the proportional solenoid's coil. Since rods and spools are not required, the number of parts is reduced and costs are reduced. Not only this, but each part will not dent or wear out and its durability will be improved.
