Abstract (en)
[origin: EP2428656A1] A variable valve timing control apparatus, includes a housing (1) rotating in synchronization with a drive shaft (C) of an internal combustion engine (E), an inner rotor (2) arranged coaxially with the housing (1) and rotatable relative to the housing (1), a driven shaft (5, 101), an intermediate member (6) arranged between the inner rotor (2) and the driven shaft (5) and rotating in synchronization with the inner rotor (2) and the driven shaft (5), a first hydraulic fluid passage (43, 73), an inner room (43b, 73b) formed between the driven shaft (5) and the inner rotor (2) and constituting a portion of the first hydraulic fluid passage (43, 73), a second hydraulic fluid passage (44, 74), a passage (44b, 74b) formed in the intermediate member (6) and constituting a portion of the second hydraulic fluid passage (44, 74), and a contact portion (A, B) at which an axial surface of the intermediate member (6) is entirely in contact with the inner rotor (2) between the first hydraulic fluid passage (43) and the second hydraulic fluid passage (44).
