Accelerator pump system |
摘要 |
An accelerator pump system is provided which consists of a pump cylinder having an intake port communicating with a float bowl and a discharge port communicated with an acceleration nozzle or pump jet which injects fuel into the throat of a carburetor. The accelerator pump includes a pump plunger which is reciprocally movable within the pump cylinder in response to pivotal movement of the throttle lever of the carburetor. A pump lever and a connecting rod including thermally responsive material such as thermo-wax are in linking arrangement between the pump plunger and the throttle lever in a series relationship in order to control the stroke of the pump plunger thereby to control the amount of fuel which is discharged into the carburetor by the pump system. As a result, the amount of fuel discharged, as well as the lever ratio of the pump lever, i.e. the fuel discharging characteristic thereof, may be controlled in response to changes in ambient temperature.
