    • An exhaust gas recirculation device in which exhaust gas from the engine of a vehicle, for example, may be recirculated via two separate lines to portions of a carburetor which are upstream and downstream of a throttle valve, to permit a suitably large amount of exhaust gas to be recirculated when necessary and which includes control means which stops the flow of gas in both lines when the engine is being warmed up, and stops the flow of gas in the upstream recirculation line only when engine load, engine speed, or vehicle speed is high, or when there is a risk of icing in the carburetor, whereby the disadvantages of recirculated exhaust gas during particular engine operating conditions are avoided.
    • 一种排气再循环装置,其中来自车辆的发动机的废气可以经由两条分开的管线再循环到在节流阀的上游和下游的化油器的部分,以允许适当大量的废气 在必要时再循环,并且包括当发动机被加热时停止两条管线中的气体流动的控制装置,并且仅在发动机负荷,发动机转速或车速为止时停止上游再循环管线中的气体流动 或者当在化油器中存在结冰的风险时,避免了在特定发动机运行条件期间再循环废气的缺点。

    • Engine acceleration detection apparatus comprising a diaphragm unit with a first chamber connected directly to a point downstream of a throttle valve in a carburetor, a second chamber connected to the same point through a delay element, a diaphragm which is provided between the first and second chambers and is displaced and causes displacement of an actuation rod element to actuate regulation means for adjustment of exhaust gas recirculation or other factors relating to engine operation when pressure increases downstream of the throttle valve, and atmosphere connection means which renders the diaphragm unit inoperative by connecting the second chamber thereof to the atmosphere in certain operating conditions, such as acceleration from high speed.
    • 发动机加速度检测装置,包括:隔膜单元,其具有直接连接在化油器中的节流阀下游的第一室;通过延迟元件连接到同一点的第二室;设置在第一和第二室之间的隔膜 并且当压力增加到节流阀的下游时,致动杆元件的位移致动用于调节废气再循环的调节装置或与发动机操作相关的其他因素;以及大气连接装置,其使得膜片单元不连接 在某些操作条件下,如从高速加速的大气中的第二室。
