摘要： A carburetor for an internal combustion engine with an accelerator fuel pump in the carburetor having a piston actuated by a cam on a throttle valve shaft and a ball between them. The axis of a pump chamber in which the piston is slidably received is offset from and eccentric to the axis of rotation of the throttle shaft so that little fuel is supplied to the operating engine by the accelerator pump as the shaft is rotated to move the throttle valve from its idle position to an intermediate position and most of the fuel supplied by the accelerator pump to the engine is delivered as the shaft is rotated to move the throttle valve from the intermediate position to its wide open throttle position. This provides a proper fuel mixture to the engine to accelerate it and avoids the problem of supplying an overly rich fuel mixture to the engine during acceleration and particularly if the operator moves the throttle valve several times back and forth between the idle and intermediate positions before moving the throttle valve to the wide open position to accelerate the engine.

摘要翻译：在化油器中具有加速器燃料泵的内燃机的化油器具有由节气门轴上的凸轮和它们之间的球致动的活塞。其中活塞可滑动地容纳的泵室的轴线偏离节流轴的旋转轴线并偏心于轴，因此当轴旋转以便使节流阀运动时，由加速器泵向操作引擎提供少量燃料阀从其怠速位置到中间位置，并且由加速器泵供给发动机的大部分燃料随着轴旋转而被传送，从而将节流阀从中间位置移动到其大的打开节气门位置。这为发动机提供了适当的燃料混合物以加速发动机，并且避免了在加速期间向发动机供应过度浓缩的燃料混合物的问题，特别是如果操作者在移动之前在空转和中间位置之间来回移动节流阀几次节气门到大开的位置，加速发动机。
