CONNECTING STRUCTRURE IN VALVE DRIVING MECHANISM FOR INTERNAL COMBUSTION ENGINES

摘要

In the suction and exhaust passages (7,7', 8,8'; 107,108) communicated with a combustion chamber (6; 106) in an internal combustion engine (1; 101), rotary suction and exhaust valves (10, 10'; 20; 110, 110', 120; 210, 210') which are capable of opening and closing these suction and exhaust passages are provided, respectively. These rotary valves have spherical valve bodies (13, 13', 23; 113, 113', 123; 213, 213'), and the driving shafts (34, 36; 134; 234) of a valve driving mechanism (30), which is adapted to rotate the valve bodies in accordance with the movement of a piston (5; 105) in the internal combustion engine (1; 101), are joined to the valve bodies via connecting members (17, 18; 117, 118; 217,218). In the case where a plurality of rotary suction valves and a plurality of rotary exhaust valves are provided, the valve bodies of the former valves and those of the latter valves are also joined to each other, respectively, via connecting members.
