摘要： A gas pressure-reducing valve in which a valve member to be seated on a valve seat having a valve hole opened at its central portion and leading to a pressure-reducing chamber between a body and a diaphragm is fixed on a valve stem connected to the central portion of the diaphragm and arranged coaxially with the valve axis. A bottomed mounting bore which is aligned with the valve axis and opened toward the pressure-reducing chamber is formed in the body. A cylindrical valve seat member forming a valve chamber between itself and the closed end of the mounting bore for accommodating the valve member and inserted into the mounting bore is fixed on the body. A valve seat facing the valve chamber is formed on the inner surface of the end portion of the valve seat member on the side of the pressure-reducing chamber. This arrangement makes it possible to reduce the number of parts and to enhance the degree of freedom for the arrangement of the parts in the body.

摘要： A gas pressure-reducing valve in which a valve member to be seated on a valve seat opened at its central portion with a valve hole leading to a pressure-reducing chamber between a body and a diaphragm is fixed on a valve stem coaxially extending through the valve hole, and in which the valve stem is fastened to a fastened member fixed on the central portion of the diaphragm. The fastened member is provided with a fitting bore opened at its one end on the side of the valve stem and a bottom threaded bore having a diameter smaller than that of the fitting bore and coaxially leading to the other end of the fitting bore. The valve stem is provided at its end portion on the side of the diaphragm with a fitting stem portion to be fitted in the fitting bore and an externally threaded portion capable of being screwed in the threaded bore and coaxially leading to the fitting stem portion. The externally threaded portion has a shorter axial length than that of the fitting bore. This arrangement makes it possible to confine the chips, as produced by screwing the valve stem into the fastened member, within the fastened member thereby to eliminate the chip removing work and to improve the assembling efficiency.

摘要： A solenoid-operated cutoff valve for use with fuel cells has a movable member disposed in a guide housing for displacement upon energization of a solenoid. When the movable member is displaced, a pilot valve is unseated from a pilot valve seat. A fluid in a communication chamber flows through a pilot passage into an output port. The communication chamber is divided into a first communication chamber and a second communication chamber by a diaphragm. Under a pressure difference developed between the first communication chamber and the second communication chamber, a main valve of a valve head is unseated from a valve seat of a valve housing, opening the solenoid-operated cutoff valve.

摘要： A first port for introducing hydrogen is defined in a side wall of a first valve body, and a hot water passage for passing therethrough hot water to heat a region in the vicinity of the first port is defined in the first valve body above the first port. The first valve body has a recess defined therein at a position facing a valve head of a valve mechanism, providing a clearance between the valve head and the first valve body when the valve head is unseated from a seating surface. A solenoid unit includes a movable core having a land which faces a recess defined in a shaft guide. An elastic member made of an elastic material is mounted on the land.

摘要： A gas pressure-reducing valve includes a pressure-reducing chamber for generating a gas pressure that acts on one surface of a diaphragm, a valve body that can sit on a valve seat having in its central part a valve hole communicating with the pressure-reducing chamber, and a spring biasing the diaphragm in a direction that detaches the valve body from the valve seat. A valve housing is formed by conjoining a body, a partition, and a cover. The partition forms the pressure-reducing chamber between itself and the body and forms a pressure action chamber between itself and the diaphragm. The cover forms the spring chamber between itself and the other surface of the diaphragm and has the peripheral edge of the diaphragm clamped between itself and the partition. The partition has a through hole for allowing the valve stem to run through in an airtight and axially slidable manner and a communicating hole for providing communication between the pressure action chamber and the pressure-reducing chamber. The structure of the body can thus be simplified thereby enhancing the machining precision, and the diameter of the pressure-reducing chamber can be determined regardless of the diameter of the diaphragm.
