Abstract

PURPOSE:To absorve a play in a link system to ensure the synchronization of a multiplex carburettor, by constituting a throttle valve link mechanism with a single drive lever and a plurality of follower levers, and as well by urging the second lever section of each follower lever by means of a spring in the direction in which a throttle valve is closed. CONSTITUTION:A drive lever 28 is coupled to a throttle valve shaft 22 in one carburettor of a multiplex carburettor, and follower levers 29, 30 are coupled to valve shafts 21, 23 in the remaining carburettors with the drive lever 28 and the follower levers 29, 30 being coupled together with the used of a coupling means 34. Each follower lever is composed of a first lever section 39 directly coupled to the associated throttle valve shaft and a second lever section 40 directly coupled to the coupling means 34 with a spring 42 being disposed between the first and second lever sections 39, 40 so that the first lever section 39 is urged in the direction in which the throttle valve is closed. The second lever section 40 is coupled to the coupling means with no gap in the direction of closing of the throttle valve.

In a throttle valve synchronization structure for a multiple carburetor in which a driven lever is connected to a shaft and a driving lever and a driven lever are connected by a connecting means, a part of the first lever directly connected to the melon valve shaft is connected. A part of the second lever connected to the stage forms a driven 1/bar, and a part of the driven lever is aligned with the first part and a part of the second lever is aligned with the first part to move the throttle valve 1 in the closing direction. Correspondence 4- Provide a bullet L1 coin that can be fired in the direction, and integrate a part of the second lever of the driven 1/par into a part of the first lever.
[A step is provided, and by the elastic force of the first step, a part of the second lever of the driven eight is connected to the step without a gap in the direction corresponding to the closing direction of the throttle valve.
In a state in which the drive lever is connected to one stage of the connection T without any gap in the direction corresponding to the opening direction of the throttle valve, integration 1 is established.
According to the stage, a part of the first lever and a part of the second lever of the J lever are integrated. Therefore, when the drive lever and the driven lever are connected by the 11-stage connection, the elastic force of the first stage causes a portion of the second lever of the driven lever to connect without any gap to the connection means in the direction corresponding to the closing direction of the throttle valve. Connect.

By integrating a portion of the second lever and a portion of the second lever, which are driven by an integrated stage in n and de, the drive lever can be easily adjusted even when there is play in the interlocking system of the multiple carburetor. Follow the rotation operation without delay.
The i1N function is to transmit the information to the engine, and the i1 function is to synchronize the opening of each throttle valve accurately and easily.
