    摘要： A valve device includes: a main valve element dividing a valve element space of a housing into first and second pressure chambers; a sealing member configured to isolate the first and second pressure chambers from each other; a first pilot passage including one end communicating with a primary passage, the other end communicating with the second pressure chamber, and a first restrictor; a second pilot passage including a second restrictor and formed at the main valve element; a pilot valve element configured to open and close the second pilot passage; a drive mechanism configured to, when a current flows through the drive mechanism, drive the pilot valve element such that the pilot valve element opens the second pilot passage against biasing force of a biasing member; and a pin coupling the main valve element and the pilot valve element to each other.

    摘要： A valve device includes a valve block having a valve port through which a fluid passes and an insertion hole; a moving valve body that opens or closes the valve port; a guide member that is inserted in the insertion hole, and slidably guides the valve body; a solenoid that generates a magnetic field when energized; a stationary pole that cooperates with the solenoid to move the valve body; a tubular support member that is inserted in the insertion hole to accommodate the solenoid, and supports the guide member that receives pressure from the fluid passing through the valve port; and a lid member that closes an opening of the support member, and the support member is joined with the valve block.

    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 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.

    摘要： A glass ball safety valve includes: a housing including a valve passage connecting a first and second port; a valve element provided in the housing so as to close the passage, the element being movable in an open direction so as to open the passage; a biasing spring configured to bias the element in the open direction; a glass ball provided in the housing so as to support the element against biasing force of the biasing spring with a space between the element and the housing in the open direction, the glass ball including a longitudinal-direction intermediate portion that breaks at a predetermined temperature, the glass ball in a broken state allowing a movement of the valve element in the open direction; and a holding body provided in the housing and holding at least one of a first longitudinal-direction end-side portion and second longitudinal-direction end-side portion of the glass ball.
