摘要： 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.

摘要： A pressure regulator valve includes: a housing including a base, a cover, and a body; a valve element configured to open and close a valve passage by moving between a closed position and an open position, the valve element being further configured to reduce a primary pressure to a secondary pressure and receive the secondary pressure by which the valve element moves toward the closed position; a biasing unit accommodated in an accommodating space formed between the body and the cover, the biasing unit being configured to bias the valve element such that the valve element moves toward the open position; a first sealing member provided at a gap between the base and the body; and a second sealing member provided a gap between the base and the cover and made of synthetic rubber. The second sealing member is arranged away from the body.

摘要： A gas solenoid valve includes: a housing; a main valve body; a guide member; a first biasing member that is disposed in a housing space formed inward of the guide member to surround the main valve body and biases the main valve body in an opening direction; a second biasing member; and an electromagnetic drive device. The housing space is spaced apart from one end of the guide member in the opening direction. A buffer groove is formed at the one end of the guide member to surround an opening end of an inner hole of the guide member.
