Abstract
A gas solenoid valve includes: a housing including a first port, a second port, and a valve port leading to the first port and the second port; a main valve body capable of moving between a closed position thereof closing the valve port and an open position thereof opening the valve port and configured to move in an opening direction from the closed position to the open position by pressure of gas supplied through the first port; a biasing member that provides a biasing force acting in a closing direction to the main valve body to position the main valve body in the closed position; and an electromagnetic drive device that generates an excitation force opposing the biasing force of the biasing member to cause the main valve body to move to the open position. A damping chamber in the housing dampens movement of the main valve body.
