摘要： [Problems]To provide a variable phase controller for an engine which assures easy manufacturing at low cost, reduces operating sound, and includes a relative rotational motion mechanism enabling quick change of a phase angle between a cam shaft and a crank shaft.[Means for Solving Problems]A variable phase controller for an engine controls the rotational motion of a first control rotor for changing the relative phase angle between a crank shaft and a cam shaft to either a phase-lead angle side or a phase-lag angle side in accordance with the direction of such control. The variable phase controller has a first braking means for rotating the first control rotor to one side, and a second braking means for braking a second control rotor and rotating the first control rotor in the direction opposite to the rotation caused by the first braking means via a second intermediate rotor (or cam guide plate) displaced by the force applied by a movable element (or rotating eccentric circular cam) displaced in guide grooves by braking of the second control rotor, thereby controlling the rotational motion of the first control rotor.

摘要： The invention provides a variable cam phaser for an automobile engine, equipped with a self-locking mechanism which is simpler in structure, cost effective, and easy to manufacture. The self-locking mechanism includes: a eccentric circular members (12) integral with the camshaft (6) and a support groove (15) for supporting the eccentric circular members from the both sides thereof at positions offset from the camshaft axis towards the eccentric cam center; a lock plate integrally held with the control rotor by means of a coupling mechanism; and a cylindrical portion belonging to the drive rotor in which the lock plate is inscribed. The self-locking mechanism prevents an unexpected change in the phase angle caused by an external disturbing toque transmitted to the camshaft via the crankshaft of the engine.
