PURPOSE:To stabilize operation by furnishing a mechanical interlocked working mechanism to angular displace No.2 throttle lever, if No.1 throttle valve is going to make an angular displacement exceeding a specific value, and thereby providing a sure interlocked action of carburettor when a transfer is made from partial load operation to high-speed operation. CONSTITUTION:A piece 20 on one side of an aux. lever 19 installed around a rotary shaft 4a, on which No.1 throttle lever 13 of carburettor C1 is mounted, transmits the opening motion of No.1 throttle lever 13 of a low-speed carburettor C1 over to No.2 throttle lever 18 of a high-speed carburettor C2 with the aid of a link device 21 and link members 22, 23. If No.1 throttle lever 13 has opened in such a degree that the opening of No.1 throttle valve 3 of carburettor C1 is going to exceed the specific value, a contact plate 16 of No.1 throttle lever 13 will push a contact piece 26 to drive the above-mentioned aux. lever 19 into the opening motion, when No.2 throttle valve 3 of the other carburettor C2 shall follow this motion and open itself. |
