APARATO BOMBEADOR DE COMBUSTIBLE LIQUIDO PARA SUMINISTRAR COMBUSTIBLE A UN MOTOR DE COMBUSTION INTERNA

摘要

A liquid fuel pumping apparatus comprises a fuel pump having an axially movable quantity control member connected to one end of a first lever which is pivoted about a fixed axis. An engine speed responsive device acts on the lever and a second lever is provided and pivoted about the said axis. A governor spring acts upon the second lever in the opposite direction to the force exerted on the first lever by the speed responsive device. Means is provided which acts to cause separation of the levers with a force which decreases as the levers move towards each other and a stop is provided to limit the movement of the second lever under the action of the governor spring. The aforesaid means is operative when the engine is at rest to cause separation of the levers to move the control member to a position at which the pump will supply an excess of fuel for starting purposes.
