摘要： PURPOSE:To obtain flatness of a transient characteristic of air fuel ratio, by constituting a carburetor such that at least two accelerating nozzles with different height of their openings to the bottom part of subwells are provided to a main well communicated to a float chamber and the delivery can be controlled in plural stages. CONSTITUTION:If a throttle valve 7 in a secondary side is fully opened by accelerating operation, intake negative pressure reaches to the inside of a bore 6 and air horn 5, and the negative pressure is applied to jets 17, 18 of accelerating nozzles 19, 20 in accordance with opening of an air valve 4. In this way, fuel 23 in a main well 9 is sucked from subwells 15, 16 and delivered from each jet 17, 18. Here at the beginning of acceleration, a large amount of fuel is delivered mostly from the jet 18, when a level of oil lowers to reach the bottom part of an opening part 22 in the subwell 16, the delivery of fuel from the nozzle 20 is stopped. And then if the level of oil is lowered below an opening part 21 of the subwell 15, fuel is balanced with a supply quantity of a jet 10 and delivered in a steady state from the acceleration nozzle 19.

摘要： PURPOSE: To prevent after-burning due to abnormal combustion in such a way that inflow air quantity to a slow speed fuel path is decreased so as to increase the fuel quantity injected from slow speed fuel injection ports when quickly shutting off a throttle valve of a carburetor.
CONSTITUTION: Slow speed injection ports 5, 6 have their opening behind a throttle valve 14 of a carburetor 1 through a slow speed fuel path 8 which communicates to a float chamber 3. Besides, main and auxiliary air bleeds 9, 11 communicate to the slow fuel path 8 in order to regulate the air-to-fuel ratio. In addition, a negative pressure path 15 equipped with a check valve 12 connects the direct rear of the both air bleeds 9, 11 to an intake air path 2 located behind the throttle valve 14. In consequence, when the throttle valve 14 is quickly shut off, intense negative pressure which occurs at the back of the throttle valve releases a chech valve 13, while producing an effect on the air bleed, so that the bleed air to the fuel path 8 can be decreased.

摘要翻译：目的：为了防止由于异常燃烧引起的后燃烧，使得减速到低速燃料路径的流入空气量减少，以便当快速关闭低速燃料喷射口的节流阀时，增加从慢速燃料喷射口喷射的燃料量化油器构成：慢速喷射端口5,6通过与浮子室3连通的慢速燃料通道8在汽化器1的节流阀14的后面打开。此外，主空气和辅助空气出口9,11与慢速燃料路径8，以调节空燃比。此外，装备有止回阀12的负压路径15将两个空气出口9,11的直接后部连接到位于节气门14后面的进气通道2.因此，当节气门14快速关闭时关闭时，在节流阀的后部发生的强烈的负压释放气门13，同时产生对排气的影响，使得可以减少到燃料通道8的排出空气。
