Jet ignition engine with singly actuated dual inlet valves

Abstract From the Canadian patent

Abstract of the Disclosure, An internal combustion engine having interconnected main and auxiliary combustion chambers respectively, sup-, plied with air-fuel mixtures through separate main and auxiliary intake passages is provided with an inlet valve having a single stem carrying two valve elements one con-, trolling each inlet port. At least one of the valve elements is resiliently positioned on the stem to permit relative movement between the elements and thus obtain positive seating of both valve elements on their respective valve seats. The arrangements permit actuation of the valve by conventional single valve actuating means.
