| description | PROBLEM TO BE SOLVED: To prevent a deterioration in operation characteristic of a valve due to the fluid pressure in an intermediate chamber located on the upstream side or the downstream side than the contact position of the wall surface composing a fluid passage and the valve. SOLUTION: A core 30 with a bottom having a hole 33a thereon is provided in the bore formed by the wall surface 22 of a body 20. The valve 50 is provided in the bore formed by the core wall surface of the core 30. The valve 50 has a bore with a bottom composed of holes 52a, 53a, 57a, a contact surface 58 to be brought into contact with the core wall of the core 50, and a valve head 59. A valve seat 40 is provided in the bore composed of the body wall surface 21 of the body 20. A communicating hole 54 for communicating spaces 21a, 22a to be formed by the valve 50 and the body 20 with the hole 52a, and a communicating hole 55 for communicating a space 30a to be formed by the valve 50 and the core 30 with the hole 33a are formed in the valve 50.
