HIGH PRESSURE SOLENOID VALVE

摘要

The present invention relates to a high pressure solenoid valve which comprises: a valve housing which has an inlet port and an outlet port and is connected to a body having a main flow channel; a fixed metal core disposed at one side of the valve housing by a magnetic force of a solenoid coil wound around the valve housing; plunger A and plunger B disposed at a lower part and pulled in order by magnetization of the fixed metal core to open the main flow channel of the body; and a main spring with elasticity disposed between the fixed metal core and the plunger B, wherein the fixed metal core is divided into a second fixed metal core fixed at one side by a disk cover joined to the valve housing and a first fixed metal core which provides a reciprocating motion from the second fixed metal core toward the plunger B and an auxiliary spring for pressing the first fixed metal core toward the plunger B is resiliently disposed between the first and second fixed metal cores or wherein the plunger B is divided into a first plunger and a second plunger in such a way that the first and second plungers are moved in the opposite directions to each other by an auxiliary spring resiliently disposed between the first and second plungers, thereby being miniaturized by reducing the flow channel inside the valve and reducing the number of components, and reducing the price and weight.
