Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To remove the part with a small sectional area of a magnetic circuit and improve the responsiveness at the time when a poppet valve is driven in the attraction direction by a solenoid, while improving the responsiveness at the time when the poppet valve is driven in the opposite direction of the attraction direction by the solenoid.
SOLUTION: A poppet valve 2 for opening/closing a jet hole 1, a solenoid 3 for attracting the poppet valve 2 electromagnetically and a spring 5 for energizing the poppet valve 2 in the opposite direction of the attraction direction by the solenoid 3 are provided.
