Abstract: The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is driven by a cam so as to swing to drive a valve, a switching pin that is attached to the rocker arm so as to be shifted between a first position and a second position, a shift device that shifts the switching pin from the first position to the second position, and a return spring that returns the switching pin. In the variable valve mechanism, a drive state of the valve is switched by shifting the switching pin, the rocker arm is formed to have such a dimension that one end of the switching pin is exposed while projecting outward from the rocker arm, and the return spring is externally fitted to the one end of the switching pin so as to be exposed outside the rocker arm.

Abstract: An engine comprises at least one cylinder, at least one piston reciprocatable within the at least one cylinder, at least one intake port through a wall of the at least one cylinder, at least one exhaust port through a wall of the at least one cylinder, at least one reciprocatable sleeve valve within the at least one cylinder for controlling porting of one or both of the at least one intake port and the at least one exhaust port, at least one shaft configured to be rotated by reciprocal motion of the at least one piston, a piston drive means coupled to and reciprocatable with the least one piston and a sleeve valve drive means coupled to and reciprocatable with the at least one reciprocatable sleeve valve. An axis of reciprocation the sleeve valve drive means is spaced from and parallel to an axis of reciprocation of the piston drive means of the at least one piston and the axis of reciprocation the sleeve valve drive means is positioned around the circumference of the shaft from the axis of reciprocation of the piston drive means of the at least one piston. This may allow the engine to be more compact and have a reduced physical size compared to some known engines.
