发明名称 SOLENOID VALVE
摘要 PURPOSE: A solenoid valve is provided to prevent rapid change of control pressure discharged through a control port by transferring some of fluid flowing from a supply chamber to a control chamber to a feedback chamber through a feedback passage formed in a spool. CONSTITUTION: A solenoid valve comprises a holder(110), a supply chamber(150), a control chamber(160), a discharge chamber(170), a feedback chamber(180), a supply port, a control port, a discharge port, a spool, a ring shaped groove, and a feedback passage. The supply chamber, the control chamber, the discharge chamber, and the feedback chamber are formed inside the holder and are separated to a longitudinal direction of the holder. The supply port, the control port, the discharge port are respectively connected to the supply chamber, the control chamber, and the discharge chamber and are formed in the outer circumference of the holder. The spool is movably installed inside the holder. The ring shaped groove is formed in the outer circumference of the spool and connects the control chamber to the supply chamber or the discharge chamber. The feedback passage is formed inside the spool, and connects or disconnects the control chamber and the feedback chamber when the spool moves.
