摘要： PURPOSE:To prevent an engine from stalling because of the intake of air through a fuel intake port when the liquid level in a float chamber is inclined at the time of acceleration, deceleration, sharp turning or the like of a vehicle, by providing a fuel accumulating portion surrounding the compensatory fuel intake port of a feedback carburetor. CONSTITUTION:A solenoid valve unit 4, which performs the feedback control of the ratio of fuel to air on the basis of the action of an exhaust gas sensor provided in the float chamber 1 of a carburetor, has a valve 7 for opening and closing the compensatory fuel jet port 6 of a passage for supplying fuel 3 to a nozzle. A fuel intake port 5 is provided in the lower portion of the solenoid valve unit 4. A fuel chamber 11 open at the top is provided in such a manner that a prescribed gap is defined between the fuel intake port 5 and the fuel chamber 11. Since the fuel 3 is accumulated in the chamber 11 of enough height, the fuel intake port 5 is not exposed to air even if the level of the fuel 3 in the float chamber 1 is greatly inclined at the time of acceleration, deceleration, turning or the like of a vehicle. The air is thus prevented from being sucked in to stall an engine.
摘要翻译：目的：为了防止发动机在通过燃料进气口进入空气时停止，当浮子室中的液位在车辆的加速，减速，急转弯等时倾斜时，通过提供燃料在反馈化油器的补偿燃料吸入口周围的蓄积部。构成：根据设置在化油器的浮子室1内的排气传感器的作用，执行燃料与空气的比例的反馈控制的电磁阀装置4具有用于打开和关闭用于向喷嘴供应燃料3的通道的补偿燃料喷射口6。燃料吸入口5设置在电磁阀单元4的下部。在顶部开口的燃料室11设置成在燃料吸入口5和燃料室11之间限定规定的间隙。由于燃料3积存在室11中足够的高度，所以即使在加速，减速，转动时浮子室1内的燃料3的高度大大倾斜，燃料吸入口5也不暴露于空气车辆的样子。因此防止空气被吸入以使发动机失速。

摘要： PURPOSE:To improve a follow-up characteristic of a bimetal, provided in an idle compensator chamber, for temperature of the outside air, by detouring an outlet of said chamber, providing a bypass passage and always replacing air in said chamber with the outside air. CONSTITUTION:An idle compensator is operated in such a manner that at a rise of the ambient temperature, a bimetal 4 in an idle compensator chamber 2 is curved leftward to move a valve 5 leftward and open a correction air passage 6. In this way, air is supplied to the downstream of a throttle valve (not shown) through intake negative pressure to prevent a mixture from becoming overrich. In this case, a bypass passage 10 is provided in the vicinity of the valve 5 to communicate said chamber to the correction air passage 6. In this way, even if the correction air passage 6 is sealed by the valve 5 at idle operation, a small amount of air is circulated to the downstream of the throttle valve to always replace air in the chamber 2 with the outside air and improve a follow-up characteristic of the bimetal 4 for temperature of the outside air.
