Fuel pump for IC engine - has two centrifugal governors linked to vary characteristic curve with speed

摘要

The pump has a rotating shaft (3). Centrifugal weights (13) on this move a spindle (15) which is connected by two levers (20, 22) to one end of a principal lever (23). The pivot (25) of the principal lever is adjustable and the other end of it is connected to the pump control rod (24). A spring (4) abutting on a flange (5) on the shaft (3) presses on a conically dished plate (9). Balls (7) in the dish are tight to the underside of a second flange (8) on the shaft. As the balls move out under centrifugal force the dish is depressed. A lever connection (10, 11) from it moves the pivot (25) of the principal lever.
