A rotary valve assembly has a valve body, a rotor and a plurality of guidance check valves. The valve body includes a valve seat longitudinally defining a bore through a center thereof. A plurality of valve oil passages and a main oil passage are respectively distributed radially around the bore. The rotor is movably received in the bore of the valve body. A plurality of guidance check valves is mounted in the valve oil passages. The rotor rotates to switch to a predetermined valve position by manual operation or electric power, where a predetermined oil supply path is precisely formed to supply oil to a predetermined valve communicating with a valve oil passage.
