SUMMARY OF THE INVENTION OBJECT To provide a simpler, axially shorter, and easy-to-manufacture phase varying apparatus for an automobile engine, utilizes a four-link mechanism consisting of multiple circular members. MEANS FOR ACHIEVING THE OBJET
An inventive phase varying apparatus has: a camshaft; drive rotor driven by the crankshaft; a first and a second torque means for rotating a first and a second control rotors, all aligned coaxially and rotatable relative to each other; and a phase angle varying mechanism operably coupled to the first and second torque means, so as to varying the relative phase angle between the camshaft and the crankshaft. The phase angle varying mechanism comprises: a circular eccentric cam integral with the camshaft; a first and a second link each having a shape of a substantially cylindrical form; and a quasi-radial guide mechanism and displacement forcing means collaborating with each other for displacing either one of the first and second links in a quasi-radial direction of the rotor. |
