  • Valve opening and closing timing control device
    Patent number: 11428172
    Abstract: A valve opening and closing timing control device includes: a driving-side rotating body that rotates synchronously with a crankshaft of an internal combustion engine around a rotating shaft core; a driven-side rotating body that rotates integrally with a valve opening and closing camshaft of the internal combustion engine around the same shaft core as the rotating shaft core; a gear mechanism that sets a relative rotation phase between the driving-side rotating body and the driven-side rotating body by displacement of a meshing position; a motor that enables displacement of the meshing position of the gear mechanism by rotating a rotating shaft; and a control unit that controls the drive of the motor. The control unit intermittently performs control to energize the motor for one phase for a predetermined time after the internal combustion engine is stopped.
