Filed: 1983-09-27
Abstract: PURPOSE:To prevent wear of a valve seat of an exhaust valve, by employing such an arrangement that the exhaust valve is moved perpendicularly to the plane of the opening of an exhaust port. CONSTITUTION:A exhaust valve is energized in the exhaust-port opening direction by a spring 9. On the opposite side of a valve seat 8, the exhaust valve comes into abutment onto a slide member 7 that is moved in the same direction as a piston 6 along with movement of the piston 6. Just before the piston 6 reaches the bottom dead point, the slide member 7 is moved upward and the abutment of the exhaust valve and the slide member 7 is removed. Then, the exhaust valve is moved perpendicularly to the plane of the opening of an exhaust port, so that the exhaust port is opened. Here, since the valve seat 8 does not cause sliding movement, wear of the valve seat is not caused, so that the durability of the exhaust valve can be improved.
