这是关于内燃机火花塞点火的分电器的一项发明。过去的分电器已经普遍地采用了带接触点的断电器,其触点是由发动机驱动的凸轮打开,并借弹簧拉力使断电臂绕转轴闭合触点。虽然此种结构在很多方面是令人满意的,但在高速时不理想,这是由于断电臂的回弹而不能准时将触点打开,结果使发动机点火不正时。 This is an invention of the distributor for the ignition of an internal combustion engine spark plug. In the past, the distributor has generally adopted a breaker with a contact whose contact is opened by an engine-driven cam and the spring is used to pull the breaker to close the contact about the shaft. Although such a structure is satisfactory in many ways, it is not desirable at high speeds due to the rebound of the de-energized arm that can not open the contacts on time, resulting in improper ignition of the engine.
