摘要： A vehicle steering device and control method for use in steer-by-wire steering systems. A steering instrument is operable to receive input from a driver and a turning device is operable to turn at least one wheel. A selectively engageable backup clutch is positioned between the steering instrument and the turning device. Engagement of the backup clutch results in a mechanical connection between the steering instrument and the turning device for assisting control of the at least one wheel, and release of the backup clutch results in a separation of the steering instrument and the turning device for steer-by-wire control of the at least one wheel. A controller is operable to switch from the steer-by-wire control to the assisting control when the backup clutch engages during operation of the steer-by-wire control.

摘要： A prestroke control device for a fuel injection pump includes at least one control sleeve slidably fitted on at least one plunger, a control rod engaging the control sleeve, the control rod extending perpendicularly to the plunger and rotatable about an axis thereof for varying an axial position of the control sleeve relative to the plunger to thereby control the prestroke of the plunger, and an actuator for rotatively driving the control rod about its own axis. A counterweight is movable in unison with rotation of the control rod for cancelling a rotating force generated by axial movement of the control sleeve and acting upon the control rod.

摘要： ABSTRACT A solenoid valve is provided in a fuel injection pump fuel supply path. A communication path communicates with each other an armature chamber, which accommodates an armature, and a spill chamber, which accommodates a head of a valve body and is connected to a lower pressure side. When high pressure fuel is spilt to the low pressure side, an orifice in the communication path reduces a high frequency pressure wave propagated from the spill chamber to the armature chamber, thus reducing deformation or corrosion of the solenoid in over a long period of use.
