    • A disadvantage for controlling idling in internal combustion engines is that when the adjusting motor is excited and the spring fails to operate, the device is fully opened and in consequence the internal combustion engine contains a dangerous amount of fuel. The device is designed so that in the exit position it opens an emergency cross-section which corresponds to point (A) on the curve and through which an emergency quantity of fuel can flow per unit time. When an adjusting motor of the device is excited, a throttle organ is first moved against the force of a spring into a position (s1) corresponding to point (B) on the curve in which the maximum possible quantity of fuel can flow through a control opening in unit time. Thereafter, the quantity of fuel per unit time is adjusted by means of the throttle organ as far as position (s2), in which position the throttle organ closes the control opening. Should the spring break while the adjusting motor is excited, the throttle organ is further adjusted into position (s4) corresponding to point (E) on the curve in which a safety cross-section is opened through which can flow a quantity of fuel per unit time less than that which flows through the fully opened control opening. The device is used to adjust idling in internal combustion engines.
    • 用于控制内燃机空转的缺点是当调节电动机被激励并且弹簧不能操作时,该装置完全打开,因此内燃机含有危险量的燃料。 该设备被设计成使得在出口位置打开一个对应于曲线上的点(A)的紧急横截面,每单位时间燃料可以通过该点紧急量流动。 当装置的调节马达被激励时,首先将节流器机构克服弹簧的力移动到对应于曲线上的点(B)的位置(s1),其中最大可能量的燃料可以流过控制器 单位时间开放 此后,通过节气门机构将单位时间内的燃料量调整至位置(s2),在此位置上,节流器关闭控制开口。 如果在调节电机被激励时弹簧断裂,则节流器件进一步调节到对应于在其上打开安全横截面的曲线上的点(E)的位置(s4),通过该点可以流动每单位燃料量 时间小于流经全开控制开口的时间。 该装置用于调节内燃机的空转。
