An output from each of output rods is converted into an assisting force via a corresponding one of rollers, while an outer peripheral surface of each of the rollers moving together with a control shaft serves as a conversion plane. This output is applied to the control shaft. Hence, as the control shaft is moved in such a direction as to increase valve lift amounts of intake valves, the assisting force can be correspondingly increased. Thus, a suitable assisting force that can act against a thrust force can be applied to the control shaft. As a result, there is no apprehension that a minimum hydraulic fluid pressure will not be ensured on the side of a larger valve lift amount or that responding properties in movements of the control shaft will deteriorate.

Assisting device and method for variable valve mechanism

A phase variation actuator has an outer rotor that is connected to a cam sprocket so that the outer rotor is rotatable together with the cam sprocket, and an inner rotor that is connected to a journal so that the inner rotor is rotatable together with the journal. The journal is rotatably supported by an internal combustion engine. A camshaft is inserted into a slide hole of the journal provided near the phase variation actuator so that the camshaft is slidable in the direction of the rotating axis of the camshaft. The camshaft is connected to the journal by meshing of splines so that the camshaft is rotatable together with the journal.

Variable valve apparatus of internal combustion engine

A variable valve timing apparatus for engines. Included are a phase adjustor for adjusting the rotational phase of a camshaft relative to a crankshaft and a lift adjustor for axially moving the camshaft. The phase adjustor has a timing pulley rotated synchronously with the crankshaft and a housing fixed to the timing pulley. A vane rotor rotated synchronously with the camshaft is arranged in the housing to define a first pressure chamber and a second pressure chamber in the housing. Hydraulic fluid is delivered to the first and second pressure chambers through oil conduits to rotate the vane rotor with respect to the housing and change the rotational phase of the camshaft relative to the crankshaft. The oil conduits extend through the timing pulley. This prevents the axial movement of the camshaft from affecting the hydraulic pressure of the pressure chambers. Accordingly, the valve timing is varied accurately.

Variable valve timing apparatus

A variable valve timing mechanism is provided at the distal end of a camshaft for changing a valve timing of an engine valve. A rotor is fixed to the distal end face of the camshaft, and the rotor has four vanes protruding radially outward. A housing is disposed to surround the rotor to be rotatable relative to the rotor and the camshaft, and the housing has recesses on the inner circumference. Each recess is divided by the vane into a first pressure chamber and a second pressure chamber. A first passage is defined in the camshaft, for supplying a hydraulic fluid pressure to the first pressure chamber so as to change the rotational phase of the second rotor with respect to the camshaft, and the first passage has an opening at the distal end face of the camshaft. A second passage is defined in the camshaft, for supplying a fluid pressure to the second pressure chamber so as to change the rotational phase of the second rotor with respect to the camshaft, and the second passage has an opening at outer circumference of the camshaft.
