  • Patent number: 8220426
    Abstract: A valve timing control device is provided with an electric motor (4) generating a magnetic retaining torque (Th) and a motor torque (Tm) in a motor shaft (102) based on a power supply. A power supply control system (6) controls the motor torque (Tm) by controlling the power supply supplied to the electric motor (4). A phase control mechanism (8) transmits a cam torque (Tca) that can alternate between a positive and a negative direction in response to rotation of a cam shaft, to the motor shaft (102) and controls a relative phase between the crank shaft and the cam shaft in accordance with a torque balance in the motor shaft (102). The power supply control system (6) eliminates the motor torque (Tm) that is balanced with the magnetic retaining torque (Th) and the cam torque (Tca) after a stop of the internal combustion engine (S105).

  • Patent number: 8076899
    Abstract: An electric power supply driver executes duty control of turning on and off of a selected switching element to supply electric power to a corresponding stator coil in a case where an actual rotational direction and a target rotational direction of a motor shaft coincide with each other. Furthermore, the driver sets an on-duty ratio of the selected switching element below a lower limit value, which is at least required to rotate the motor shaft through the power supply to each corresponding stator coil in a case where the actual rotational direction and the target rotational direction do not coincide with each other.

  • Patent number: 7959537
    Abstract: A first rotary member rotates with a crankshaft and has a first gear. A second rotary member rotates with a camshaft and has a second gear that is axially shifted from the first gear. A planetary rotary member has third and fourth gears, which are eccentrically meshed respectively with the first and second gears to perform a planetary motion. A biasing member is interposed between the planetary rotary member and a planetary carrier, which supports the planetary rotary member. The planetary rotary member is in contact with the biasing member at a contact portion having an axial center. The axial center is located on a radially inner side of a meshed portion between the second and fourth gears, which has a backlash larger than that of a meshed portion between the first and third gears.

  • Patent number: 7669568
    Abstract: A valve timing controller has a shaft body as an output rotor, a torque generating system which generates the controlling torque outputted from the shaft body, and a planet carrier as an input rotor connected with the shaft body. A phase adjusting mechanism adjusts the relative rotational phase between a crankshaft and a camshaft according to the control torque inputted into the planet carrier from the shaft body. A bearing rotatably supports the planet carrier. The planet carrier forms a cylindrical input wall press-inserted in an inner circumference of the bearing. The input wall is provided with a fitting recess on its inner surface for engaging with the shaft body, the input wall is provided with a thin-wall portion of which thickness is reduced in a radial direction, and the fitting recess and the thin-wall portion are circumferentially arranged apart from each other.
