<p>The present invention relates to the internal combustion engine with hydraulic actuating mechanism for inlet and exhaust valves. The actuating mechanism comprises a housing, an inlet-rotating valve and a outlet-rotating valve and their linings provided in the housing respectively. Inlet and drain oil passages being in turn aligned with the inlet and drain oil holes in the lining are provided in the radial cross section of the inlet-rotating and outlet-rotating valves which are respectively provided with in-phase gears meshing with each other. One axial end of a rotating valve is supplied with a driven timing gear, which is meshed with a timing gear installed on the crankshaft. Hydraulic pistons, each having a piston lever, are provided under the linings for the inlet-rotating and outlet-rotating valves. A piston lever makes a inlet or exhaust valve to move. The present invention can overcome disadvantages of the short duration for the inlet and exhaust valve in complete open, and disadvantage-effects on the power of the engine by increasing gap of the valve, and has the advantage to reduce the consumption of the power by the engine itself.</p> |
