发明名称 VARIABLE VALVE ACTUATING APPARATUS FOR INTERNAL COMBUSTION ENGINE
摘要 PROBLEM TO BE SOLVED: To provide a variable valve actuating apparatus arranged to control a relative rotational phase between an inner cam shaft and an outer cam shaft, to control relative rotational phases of the inner cam shaft and the outer cam shaft with respect to a crank shaft, and to miniaturize the apparatus in an axial direction.SOLUTION: A variable valve actuating apparatus comprises a first vane rotor 10 fixed to an outer cam shaft 5 and a second vane rotor 23 fixed to an inner cam shaft 6. The second vane rotor is relatively rotatably housed in a parallel arrangement state in a rotor receiving space 19c and a vane receiving space 22a formed in a first rotor 19 of the first vane rotor and a third vane 22. The variable valve actuating apparatus comprises a first lock mechanism 28 locking a relative rotation position of the first vane rotor in response to a request and a second lock mechanism 41 locking a relative rotation position of the second vane rotor in response to the request.
