摘要： A device for controlling a phase of a cam shaft in an internal combustion engine has a structure which can return a phase of a cam shaft to an intermediate position on the basis of its own power by utilizing a variable torque applied to a cam shaft at a time of starting an engine so as to lock, and has a high practicability and mass production performance. This device is provided with a first rotating body rotating together with a cam shaft, a second rotating body provided coaxially in the first rotating body so as to control a phase angle and rotating together with a sprocket, and a fixing mechanism fixing the phase angle, in which the fixing mechanism has a wedge member wherein a wedge-shaped portion is formed, the first rotating body and the second rotating body have contact surfaces brought into contact with the wedge member, and at least any one of the contact surfaces of the first rotating body and the second rotating body is formed such that a distance from a center of rotation to an application line of a load applied to the contact surface is smaller than a distance from the center of rotation to an application point of the load on the contact surface.

摘要： A plurality of advanced angle chamber oil paths communicated to advanced angle hydraulic chambers and a plurality of retarded angle chamber oil paths communicated to retarded angle hydraulic chambers according to a change in rotating angle of a cam shaft are provided. The plurality of advanced angle chamber oil paths and the plurality of retarded angle chamber oil paths, respectively, are switched between communication and cut-off according to a rotating angle of the cam shaft. When torque in the direction of advanced angle acts in an advanced angle mode for phase shifting in the direction of advanced angle, the advanced angle hydraulic chambers are caused to communicate to a hydraulic power source and the retarded angle hydraulic chambers are caused to communicate to a drain. Also, at high speed of an engine, in the advanced angle mode, shut-off valves in the advanced angle chamber oil paths and the retarded angle chamber oil paths are opened so that hydraulic pressure is communicated from the hydraulic power source to the advanced angle chambers at all times in the same manner as in the related art.
