気弁。[Claims for Utility Model Registration] 1. An engine in which valve chambers 5, 6 are formed in the middle of intake and exhaust ports 3, 4 of an engine 1, and rotary valves 7, 8 are rotatably fitted in the valve chambers 5, 6. In the rotary intake and exhaust valve, high pressure gas in the combustion chamber 11 is transferred to the intake and exhaust ports 3 and 4.
A pair of elastic seal rings 13 and 14 surround the intake and exhaust ports 3 and 4 in the valve rotation gap 12 to prevent leakage from the valve chambers 5 and 6 to the valve rotation gap 12 between the rotary valves 7 and 8. The base ends 13a, 14a of each elastic seal ring 13, 14 are hermetically fixed to the inner peripheral surfaces of the valve chambers 5, 6, and the distal ends 13b, 14b are hermetically sealed to the rotary valves 7, 8. The high-pressure fluid inlet passage 18 and outlet passage 19 are connected to the valve rotation gap 12 between both elastic seal rings, and the high-pressure fluid from the high-pressure fluid supply device attached to the engine 1 is passed from the inlet passage 18 to the valve rotation gap. A rotary intake/exhaust valve for an engine, characterized in that the rotary intake/exhaust valve for an engine is configured to allow the air to pass through the interior of the engine and flow out from the outlet passage 19. 2. The rotary intake and exhaust valve for an engine according to claim 1, wherein the inlet passage 18 or the outlet passage 19 passes through the valve shafts 9, 10 of the rotary valves 7, 8.
