Abstract
Intake and exhaust rotary valves (10, 10', 20; 110, 110', 120; 210, 210') are separately disposed in intake and exhaust passages (7, 7', 8, 8'; 107, 108) communicating with a combustion chamber (6; 106) in an internal combustion engine (1; 101), respectively, and are adapted to open and close the corresponding intake and exhaust passages. These rotary valves have spherical valve bodies (13, 13', 23; 113, 113', 123; 213, 213'). A valve operating system (30) for rotatively driving the valve bodies interlockingly with the movement of a piston (5; 105) in the internal combustion engine (1; 101) has drive shaft (34, 36; 134; 234) each of which is connected to the valve body through a connecting member (17, 18; 117, 118; 217, 218). In case a plurality of the intake and exhaust rotary valves are mounted, the valve bodies of the intake rotary valves as well as the valve bodies of the exhaust rotary valves are also interconnected through connecting members.
