摘要： A movable core sliding in a guide portion includes a small outer-diameter part, a large outer-diameter part, and a protrusion part. When a magnetic circuit is generated by energizing a coil, a magnetic attractive force inclining with respect to a center axis of the guide portion is generated between the guide portion and the movable core, and moves the movable core towards a stator core. Then, a sliding portion, which is provided over the whole periphery of the small outer-diameter part, and the protrusion part of the movable core are abutted on an inner peripheral surface of the guide portion, a clearance is generated between an outer peripheral surface of parts of the movable core except the protrusion part and the inner peripheral surface of the guide portion. Since the valve member can be opened by a small magnetic attractive force, a coil assembly can be made small.

摘要： A guide portion made of a magnetic material can be filled with a gaseous fuel of high-pressure and is slidably receiving a movable core. The guide portion is constructed by a first small-diameter portion, a second small-diameter portion, and a magnetism blocking portion having a wall thickness less than that of the first small-diameter portion and the second small-diameter portion. When a magnetic circuit is generated by energizing the coil, a magnetic flux passing through the first small-diameter portion passes through the second small-diameter portion via an end face of the movable core and generates a magnetic attractive force inclining with respect to a center axis. Therefore, the movable core is moved to the stator core by the magnetic attractive force adding a magnetic attractive force generated by a magnetic circuit.

摘要： A guide portion slidably receiving a movable core is constructed by a medium-diameter portion, a first small-diameter portion, and a second small-diameter portion. A magnetism blocking portion is provided between the first small-diameter portion and the second small-diameter portion. A ring portion is provided at a periphery of the medium-diameter portion, and abuts on a yoke. When a coil is energized, a magnetic circuit is generated to pass through the yoke, the medium-diameter portion, the first small-diameter portion, the movable core, and the second small-diameter portion, and to bypass the magnetism blocking portion. In addition, another magnetic circuit passing through the ring portion is also generated. A magnetic attractive force inclining with a center axis of the guide portion is generated between the second small-diameter portion and an end surface according to an expansion magnetic circuit, and the movable core is moved towards the stator core.

摘要： Torque of a prime mover is input into a sun gear. A planetary gear revolves in a circumferential direction of the sun gear while rotating and meshing with the sun gear. A carrier has an annular shape, rotatably supports the planetary gear, and is rotatable relative to the sun gear. A first ring gear is fixed to a housing, and meshes with the planetary gear. A second ring gear meshes with the planetary gear, is different from the first ring gear in number of teeth of a tooth portion, and outputs torque to a rotation portion. At least a part of the sun gear in an axial direction is located radially inward of the carrier. At least a part of the first ring gear and at least a part of the second ring gear in the axial direction are located radially outward of the carrier.

摘要： A normal-time drive cam groove extends from a drive cam specific point, which is defined as a specific point of the drive cam, toward one side in a circumferential direction of the drive cam. A groove bottom at the normal-time drive cam groove is sloped relative to one end surface of the drive cam such that a depth of the groove bottom continuously decreases from the drive cam specific point toward the one side in the circumferential direction of the drive cam. An emergency-time drive cam groove extends from the drive cam specific point toward another side in the circumferential direction of the drive cam.

摘要： A guide portion slidably receiving a movable core is constructed by a large-diameter portion, a middle-diameter portion, a first small-diameter portion, a magnetism blocking portion, and a second small-diameter portion. A ring portion, which has an outer diameter greater than that of a coil assembly provided radially outside of the guide portion, is provided radially outside of the middle-diameter portion. When the guide portion attached with the coil assembly is attached to a support member corresponding to a mating member, the guide portion is attached to the support member by applying a rotational torque of to the ring portion in an axial direction of the guide portion according to a tool without an interference between the tool and the coil assembly. Therefore, an electromagnetic valve device for a gaseous fuel can be readily attached to the support member.

摘要： A housing includes an accommodation space for a prime mover and a speed reducer. A rotational translation unit includes a rotation portion that rotates relative to the housing upon receiving torque outputted from the speed reducer, and a translation portion that moves relative to the housing in an axial direction according to rotation of the rotation portion. The accommodation space is between the rotation portion and the housing. A clutch in a clutch space allows or interrupts transmission of torque between a first transmission portion and a second transmission portion. The rotation portion is between the clutch space and the accommodation space. A sealing member has an annular shape in contact with the rotation portion, and maintains an air-tight or liquid-tight state between the accommodation space and the clutch space.
