Abstract
In a solenoid valve device, a housing has a stopper formed on an inner wall of a fluid passage around an axial end of an accommodation bore. A valve seat member fixed to an inner circumferential wall of the fluid passage has a through-hole causing an input port to communicate with a drain port, a communication bore causing the through-hole to communicate with an output port and first and second valve seats formed around both ends of the through-hole, respectively. A movable member has a contact portion accommodated in the fluid passage between the stopper and the second valve seat. A ball is arranged on an opposite side to the contact portion with respect to the valve seat member. When the movable member moves with a movable core, the contact portion resting at the stopper or the second valve seat defines reciprocating moving stroke of the movable member.
