を特徴とする、エンジンの回転式吸排気弁。[Claim for Utility Model Registration] Rotation of an engine in which valve chambers 5 and 6 are formed in the middle of intake and exhaust ports 3 and 4 of an engine 1, and rotary valves 7 and 8 are rotatably fitted in the valve chambers 5 and 6. In the type intake/exhaust valve, high pressure gas in the combustion chamber 11 flows through the intake/exhaust ports 3 and 4.
An elastic seal ring 13 that prevents leakage from the port portions 3a, 4a on the combustion chamber 11 side into the valve rotation gap 12 between the valve chambers 5, 6 and the rotary valves 7, 8.
is inserted into the portion surrounding the port portions 3a, 4a on the side of the combustion chamber 11 in the valve rotation gap 12, and the base end portion 13a of the elastic seal ring 13 is hermetically fixed to the inner circumferential surface of the valve chambers 5, 6. Tip part 13b, 1
A rotary intake/exhaust valve for an engine, characterized in that 3c and 13d extend toward the side approaching the port portion on the side of the combustion chamber 11 and are brought into airtight contact with the rotary valves 7 and 8.
