摘要： A valve device includes an operating unit, a first pushing member, a plate-like member, a second pushing member, and a valve. The plate-like member includes a plurality of the moment arms arranged at intervals in a circumferential direction. A force point of each of the plurality of the moment arms is pushed by a front end of the first pushing member. The second pushing member has an acted surface receiving a force from an action point of each of the plurality of the moment arms. The plurality of the moment arms are integrally connected by an annular frame portion of the plate-like member where the fulcrum is disposed.

摘要： A valve mechanism includes: a cylindrical body; a plurality of valve bodies; and a drive valve. The drive valve includes a shaft portion having therein a flow path penetrating in the axial direction, and a step portion extending from an outer peripheral surface of the shaft portion to a radial outside of the shaft portion. The shaft portion has a tip portion which extends further on the cylindrical body side than the step portion. An outer diameter of the tip portion is smaller than an outer diameter of the step portion. A gap between the valve bodies is changed by elastically deforming an inner peripheral portion of the valve body, which comes into contact with the drive valve moved in a direction approaching the valve body, in a direction approaching the cylindrical body with respect to an outer peripheral portion of the valve body.

摘要： A vehicle height adjustment device includes a rear suspension, an electromagnetic valve control unit, and a weight estimation unit. The rear suspension includes a support member. The electromagnetic valve control unit determines a target movement based on an interrelation between the target movement and a weight applied to a vehicle, under which the target movement is set to an upper limit when the weight is larger than a predetermined weight, so that an actual movement of the support member reaches the target movement. The electromagnetic valve control unit determines the target movement based on a temporary weight. The weight estimation unit increases the temporary weight, even when the actual movement reached the target movement. The electromagnetic valve control unit decreases the target length, even when the temporary weight increased. The weight estimation unit estimates as the weight the temporary weight when the actual length has finally reached the target length.

摘要： A suspension device includes: a damping device that damps a force generated between a vehicle body and a wheel of a vehicle; a determination unit that determines whether the vehicle is jumping, using an acceleration of the vehicle in a front-rear direction, an acceleration of the vehicle in a left-right direction, and an acceleration of the vehicle in a vertical direction; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when the determination unit does not determine that the vehicle is jumping, when the determination unit determines that the vehicle is jumping.

摘要： A hydraulic shock absorber includes a control valve. The control valve includes a valve seat formed with a closing face, a valve body configured to come into contact with the closing face, and a valve shaft configured to transmit an operation force applied from a driving unit to the valve body. The control valve is defined with an upstream side flow channel extending from an inlet coupled to the upper end opening, via a space in which the valve body moves, to the closing face, and a downstream side flow channel extending from the closing face to an outlet. The control valve is disposed above the cylinder so that a central axis of the valve shaft is inclined relative to a central axis of the vehicle body side tube and the wheel side tube.

摘要： A vehicle height adjustment device includes front forks, a rear suspension, a weight estimation unit, and a front wheel-side target movement amount determination unit. The front fork includes a front wheel-side suspension spring and a front wheel-side support member, which supports one end of the front wheel-side suspension spring, and moves toward another end of the front wheel-side spring to change the front wheel-side suspension spring length. The rear suspension includes a rear wheel-side suspension spring and a rear wheel-side support member, which supports one end of the rear wheel-side suspension spring, and moves toward another one end of the rear wheel-side spring to change the rear wheel-side suspension spring length. The weight estimation unit estimates a weight applied to a vehicle. The front wheel-side target movement amount determination unit decreases, a movement amount of the front wheel-side support member as the estimated weight increases.

摘要： A flow path control device according to one embodiment includes a first valve, a unit main body and a control valve. The unit main body has an accommodation portion, a first radial communication hole and a side recess portion. The accommodation portion is recessed from a chamber accommodating the oil to cause the first valve to close the first radial communication hole. The side recess portion is recessed from the chamber so as to be continuous to the accommodation portion and not to be continuous to the first radial communication hole. The control valve is movable in the accommodation portion of the unit main body between a position at which a groove of the control valve communicates with the side recess portion and the first radial communication hole and a position at which the groove does not communicate with them.
