Abstract:
1. A valve timing controller controlling a valve timing of a valve opened and closed by a torque transmitted to a camshaft from a crankshaft of an internal combustion engine, the valve timing controller comprising: a housing rotating with the crankshaft; a vane rotor rotating with the camshaft and partitioning an interior space of the housing into an advance chamber and a retard chamber in a rotation direction, a rotation phase of the vane rotor relative to the housing being changed in an advance direction or a retard direction by introducing working fluid into the advance chamber or the retard chamber; a control valve disposed in an interlocking rotor constructed by the vane rotor and the camshaft, the control valve having a sleeve in which the working fluid flows and a spool reciprocating in the sleeve in an axial direction, the control valve controlling a flow of the working fluid relative to the advance chamber and the retard chamber based on a reciprocation of the spool in the sleeve; and a linear solenoid driving the spool to reciprocate in the axial direction, the linear solenoid including the output shaft has an end surface that contacts a sphere-shaped end face of the spool, at a contact position offset in a radial direction from a center axis of the spool.
