Abstract: A valve timing control device includes a lock mechanism having a hole portion formed in one of the driving-side/driven-side rotational members, a sleeve in the hole portion, a lock member in the sleeve and capable of projecting and retracting with respect to the other of the driving-side/driven-side members, and a lock hole formed in the other of the driving-side/driven-side members such that the lock member can be fitted to the lock hole when the lock member projects. The lock mechanism constrains a relative rotational phase of the driven-side rotational member with respect to the driving-side rotational member at a predetermined phase when the lock member is fitted to the lock hole. A first chamfered surface is formed in the circumferential direction at an inner-circumferential corner of an end of the sleeve on the side opposite to the side facing the lock hole.

Abstract: In a valve timing control apparatus configured to enable rotary motion of a vane rotor relative to a housing, a recessed-groove passage is formed in the inside end face of the housing. A circumferential length of the recessed-groove passage is dimensioned to be greater than a circumferential width of the associated vane. The recessed-groove passage permits fluid-communication between a phase-advance hydraulic chamber and a phase-retard hydraulic chamber by way of both circumferential ends of the recessed-groove passage at a maximum phase-retard position of the vane rotor relative to the housing. Even when an engine stall has occurred during a low-temperature engine operating condition with the vane rotor positioned nearer the maximum phase-retard position, the vane rotor can rapidly rotate to its lock position by a fluttering motion, caused by alternating torque and multiplied by fluid-communication between the phase-advance hydraulic chamber and the phase-retard hydraulic chamber through the recessed-groove passage.

Abstract: A rotor (1, 21, 41) for a camshaft adjuster (61), having a rotor base body (3, 23, 43) and a number of rotor blades (5, 25, 45) extending radially outwards and located on the rotor base body (3, 23, 43), each of the blades having a blade end (7, 27, 47). To reduce leakage, the blade ends (7, 27, 47) of the rotor blades (5, 25, 45) take the form of sealing fins (9, 31, 49) that can be deformed radially outwards. A rotor (1, 21, 41) of this type affords the possibility of reducing leakage in a camshaft adjuster (61) using simple engineering and without added costs. The invention also relates to a camshaft adjuster (61) for an internal combustion engine, including a rotor (1, 21, 41) of this type.

Also provided is a decentering mechanism supporting the control housing rockably to produce the eccentric motion of the annular disc. A locus of eccentric motion of the center of the annular disc arranged in the left bank and a locus of eccentric motion of the center of the annular disc arranged in the right bank are essentially symmetrical with respect to the line perpendicular to a line segment between and including two central axes of said drive shafts of the two cylinder banks. A direction of eccentric motion of the center of the annular disc arranged in the right bank is opposite to a direction of eccentric motion of the center of the annular disc arranged in the left bank.
