Abstract: A first-type passage switching valve is provided in an oil supply line connecting a friction element to an N/H type pressure control valve and a second-type passage switching valve is provided in another oil supply line connecting another friction element to an N/L type pressure control valve. A working-pressure output valve outputs a hydraulic working pressure to each of the first-type and the second-type passage switching valves. The first-type passage switching valve changes its communication condition from a first communication state connecting the friction element and the pressure control valve with each other to a second communication state connecting the friction element and a drain side with each other, or vice versa. The second-type passage switching valve changes its communication condition from a first communication state connecting the friction element and the pressure control valve with each other to a third communication state connecting the friction element and a hydraulic pressure source with each other, or vice versa.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A prime mover includes a stator fixed to the housing and a rotor rotatable relative to the stator. The prime mover outputs torque by being supplied with electric power. A speed reducer reduces the torque of the prime mover and outputs the reduced torque. A rotational translation unit includes a rotation portion that rotates relative to the housing upon receiving the torque from the speed reducer, and a translation portion that moves relative to the housing in an axial direction. A clutch allows torque transmission in an engaged state, and interrupts the torque transmission in a disengaged state. A state changing unit changes the state of the clutch by receiving a force along the axial direction from the translation portion. Cogging torque generated between the rotor and the stator is set to such a magnitude that the rotor is stoppable at any rotation position relative to the stator.

Abstract: 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.

Abstract: A critical state is assumed in which a position of one end of the opening of the input port in the axial direction and a position of the other end of the groove in the axial direction accord with each other with respect to the axial direction. In the critical state, when a straight line is extended in the axial direction as well as radially outward of the spool without changing a direction of the straight line in a circumferential direction of the spool from one end of the groove bottom in the axial direction with the same inclination as the inclination of the groove bottom at the one end of the groove in the axial direction relative to the axial direction, the straight line passes through the opening of the output port to contact a wall surface of the output port.

Abstract: A spool valve includes a valve housing and a spool. The spool is slidable in an axial direction in the valve housing. A linear solenoid drives the spool against a spring. The valve housing has a feedback chamber to apply a force to the spool, an input port to receive a hydraulic pressure, an output port to produce an output pressure according to an axial position of the spool, and an drain port to exhaust oil to an outside. The spool valve has multiple supply paths to cause oil to flow from the input port to the output port and/or multiple exhaust paths to cause oil to flow from the output port to the drain port.

Abstract: 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.
