Title:
SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2017/033645
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a solenoid valve that can stabilize injection volumes even when the injection continues while an intermediate member continues to displace after closing the valve until a closed valve standby state is restored. Therefore, a valve (303) opens and closes a flow channel. A movable iron core (404) moves the valve (303) in the valve opening direction by way of magnetic attractive force. An intermediate member (414) is configured so that a preliminary stroke gap (g1) is formed between the movable iron core (404) and the valve (303) in the closed valve state. A stopper (410c) collides with the intermediate member (414) when the intermediate member (414) moves in a direction to make the preliminary stroke gap (g1) smaller.
