摘要: A fuel injection pumping apparatus includes a governor which controls the size of an orifice through which fuel is supplied to an injection pump to determine the amount of fuel supplied by the pump to an associated engine. The governor includes a piston which at one end is subjected to fuel pressure and which bears at its other end against a spring connected in series with a spring. The spring is weaker than the spring so that at idling speed it is the spring which balances the force acting on the piston. Manually operable means is provided to effect movement of an abutment disposed between the springs, the spring acting to determine the maximum speed of the associated engine. When the engine has been started from cold, it is desirable to provide additional fuel to enable the engine to idle properly and for this purpose a device represented by the arrow, moves the end of the spring remote from the spring and this provides a temporary increase in the amount of fuel supplied at idling speeds.

摘要: A fuel injection pump of the rotary distributor type has a main pumping chamber including a bore in which is located a plunger and an auxiliary pumping chamber including a further bore and a further plunger. Speed responsive valve means is provided which connects the two bores together for starting purposes. In order to permit air to escape from the bores a spill passage is connected by a passage to the further bore and the spill passage is brought into communication with a spill port while fuel is being supplied to the bores.
