Oil pressure type valve time control device for e.g. inlet valve of internal combustion engine of vehicle, has rotor periodically receiving torque, and specific-shaped part extending from wing in direction opposite to mean value direction

摘要

The device (10) has a sliding piece (131) including an end section, which is cut relative to a cylinder part (130) in a radial direction from an edge of the end section adjacent to a wing (161) in an early adjustable direction or a delay direction. A wing rotor (16) periodically receives a shifting torque in the delay direction or the early adjustable direction adapted to rotation of camshafts. A mean value of torque fluctuation affects acts on the rotor in a mean value direction. A specific-shaped part (20) extends from the wing in a direction opposite to the mean value direction. An independent claim is also included for a valve time controller.
