Abstract
A linear solenoid valve apparatus for discharging foreign matter collected at the exhaust port by engaging the electromagnet of the linear solenoid valve. The apparatus includes a linear solenoid valve having a valve sleeve, a spool, a spring, and an electromagnet, and a modulator valve including an exhaust port in which foreign matter is collected. The electromagnet is energized by foreign matter discharging control, responsive to detection of lack of need for output pressure from the solenoid valve, so that the foreign matter is discharged from the exhaust port.
