- the inner diameter D0 of the discharge port 51 is specifically determined by the relationship between the total flow path cross-sectional area S0 of the discharge port 51 described later and the maximum opening area S1 of the valve portion. The same applies to the input port 53.
- the input port 53 is a port into which a control fluid (for example, hydraulic oil) supplied by a pump from a tank (not shown) flows.
- the discharge port 51 is a port for supplying control fluid to a fluid request destination (load) such as an automatic transmission (not shown).
- the feedback port 54 and the control port 52 communicate with each other outside the solenoid valve 10, and a part of the control fluid flowing out from the control port 52 flows into the feedback port 54.

It is like that. More specifically, when the spool 60 moves in the axial direction Z inside the valve sleeve 41, the outer peripheral surface 63 a of the first land portion 63 slides along the valve seat inner peripheral surface 47 of the valve sleeve 41. Thus, the distance W between the rear end 63b of the first land portion 63 and the rear end side surface 44b of the ring-shaped groove becomes 0 or less.

Therefore, in addition to the pressing force based on the pressure FB of the control fluid from the feedback port 54, the pressing force of the spring 42 and the pressing force due to the movement of the plunger 24 are transmitted to the spool 60 via the rod 26. With these pressing forces, the spool 60 slides in the valve sleeve 41 in the axial direction Z.

- the amount of control fluid flowing from the control port 52 to the discharge port 51 is determined by the distance W between the rear end 63b of the first land portion 63 and the rear end side surface 44b of the ring-shaped groove.
- the solenoid valve 10 configured as described above, when a current is supplied from a control circuit (not shown) to the coil 22 of the solenoid unit 20, the coil 22 generates a magnetic field in a desired direction with a desired strength.
- the plunger 24 is moved by the electromagnetic force generated by the magnetic field.
