Abstract: An automatic choke apparatus for use in an internal combustion engine. The choke apparatus includes a choke valve automatically operable in response to the speed of the engine, a thermally conductive assembly that conducts heat from exhaust gases produced by the engine, a thermally responsive member in thermal communication with the thermally conductive assembly, and a mechanism that moves in response to the thermally responsive member to cause the choke valve to remain in at least a partially open position during engine starting when the thermally responsive member senses a temperature above a predetermined temperature. The thermally conductive assembly at least partially surrounds the path of the exhaust gases.

Abstract: A self-relieving choke adjustment apparatus for an internal combustion engine carburetor including a choke valve body and a choke mixing passage formed in the valve body. A choke plate is supported in the mixing passage for pivotal motion about a parallel choke plate axis between an open position and a closed position, such that airflow through the mixing passage tends to rotate the choke plate toward the open position. A rotary biasing element is connected between the choke plate and the choke body and applies a torque biasing the choke plate toward its closed position. The apparatus also includes a choke adjustment lever supported for pivotal motion relative to the choke plate about the choke plate axis and rotationally engaging the biasing element such that lever rotation against the biasing force of the biasing element causes the biasing torque applied to the choke plate by the biasing element to increase thus increasing the amount of airflow required to rotate the choke plate out of its closed position and decreasing the number of degrees the choke plate will be forced open by a given amount of airflow through the mixing chamber.

Abstract: In a motion transmitting mechanism for controlling a power output control member such as a butterfly valve of an internal combustion engine, wherein a control input member is operatively connected to an input lever which cooperates with an output lever by means of a projection received on a guide slot formed in the input lever, the guide slot has first and second slot sections arranged at an angle and adapted to operate the output lever and the power output control member at a relatively small motion transmission ratio with a relatively large incremental operating force increase in a lower partial load range when the projection is in the first slot section and at a relatively high motion transmitting ratio with relatively small incremental operating force increase in a higher partial load range.

Abstract: A throttle stop assembly for an internal combustion engine is provided to return the throttle shaft to an idle position from a full throttle position in the event a loose throttle level mounting bolt occurs. The throttle stop assembly is designed to for the throttle shaft stop element from the full throttle position to the idle position if the throttle lever mounting bolt assembly fails, thereby preventing the engine from continuing to run in an advanced throttle condition. The stop assembly of the present invention includes a spring-biased piston contained within a threaded, hollow shaft. The spring biased piston has no effect on throttle shaft position except when the normal throttle shaft operating system fails in which case the spring biased piston will cause the throttle shaft to return to its idle position.
Abstract translation: 提供一种用于内燃机的节气门止动组件，用于在节气门水平安装螺栓松动的情况下将节气门从全节气门位置返回到空转位置。 如果节气门杆安装螺栓组件失效，则节气门止动组件被设计成用于使节气门轴止动元件从全节气门位置到空转位置，从而防止发动机在高级节气门状态下继续运行。 本发明的止动组件包括容纳在螺纹空心轴内的弹簧偏置活塞。 弹簧偏置的活塞对节气门轴位置没有影响，除了当正常节气门轴操作系统发生故障时，在这种情况下，弹簧偏置的活塞将导致节气门轴返回到其空转位置。
