摘要:
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).
摘要(中):
本发明涉及一种用于二冲程内燃机的化油器组件(10),该组件包括容纳节流阀(30)的主进气通道(12),容纳额外空气阀的附加空气通道(14) 与空气阀(50)一起转动的可枢转的空气阀杆(55)和与节流阀(30)一起转动的互锁杆(35)。 联锁杆35被构造成能够在一定的枢转位置中被设定,其中节气门30打开一定程度以便提供节流阀30的起始气体位置,其中联锁 如果联动杆35沿节气门30的打开方向进一步枢转,则被布置成释放。 该组件还包括一个可枢转的触发杆(45) 拉动节流触发器并且可操作地连接到空气阀杆(55)。 可转动触发杆(45)可操作地连接到联锁杆(35)或与触发杆(45)和互锁杆(35)的预定相对位置处的邻接接合件通过联锁杆(35)移动的构件 )。 此外,触发杆(45)被布置成允许联锁杆(35)在节气门(30)的打开方向上远离邻接接合枢转至少相对于触发杆的偏移角() 使得可以将联动杆35设定在联锁位置而不影响触发杆45的枢转位置。
