Carburetor assembly
Document Type and Number:
Japanese Patent JP6203390
Kind Code:
B2
Abstract:
The invention relates to a carburetor assembly (10) for a two-stroke internal combustion engine, the assembly comprising a main intake passage (12) accommodating a throttle valve (30), an additional air passage (14) accommodating an additional air valve (50), a pivotable air valve lever (55) turning together with the air valve (50), and an interlock lever (35) turning together with the throttle valve (30). The interlock lever (35) is configured to be settable in an interlocked pivotal position, in which the throttle valve (30) is open to a certain degree in order to provide a start gas position of the throttle valve (30), wherein the interlock is arranged to be released if the interlock lever (35) is pivoted further in the opening direction of the throttle valve (30). The assembly further comprising a pivotable trigger lever (45) responsive to e.g. pulling of a throttle trigger and being operatively connected to the air valve lever (55). The pivotable trigger lever (45) is operatively connectable to the interlock lever (35) or a member that moves with the interlock lever (35) via an abutting engagement at predetermined relative positions of the trigger lever (45) and the interlock lever (35). Further, the trigger lever (45) is arranged to permit the interlock lever (35) to pivot away from the abutting engagement in the opening direction of the throttle valve (30) at least to an offset angle ( ) relative to the trigger lever (45), such that the interlocked lever (35) can be set in the interlocked position without affecting the pivotal position of the trigger lever (45).
