Title: Liquid fuel injection pumping apparatus
IPC: F02M59/02
Filed: 1971-11-13
Abstract: 1406432 Fuel injection pumps CAV Ltd 2 Nov 1972 [13 Nov 1971] 52814/71 Heading F1A When the delivery of a fuel injection pump having a separate outlet 11 to each engine cylinder is adjusted below a predetermined value, the flow of fuel to at least one outlet is cut off whilst the flow to the remaining outlet or outlets is increased. The pump shown has a plurality of cylinders in each of which is reciprocated a piston 13 or a piston 14, the pistons being simultaneously  rotatable to vary the delivery. On rotation of the pistons to a position corresponding to a delivery less than the predetermined value, a control edge on the or each piston 14 causes permanent spillage of fuel from the associated cylinder(s) whilst a step on the control edge of the or each piston 13 causes an increase in delivery from the associated cylinder(s).

A manually engageable unidirectional drive means 1, 6 between the spindle 5 and drum 8 permits either the direct drive in one rotational sense of the spindle, or one or other of the reduction gear drives depending on the rotational sense of the spindle, unidirectional devices in both reduction gear trains determining the ratio in response to the spindle sense. The reduction gear trains comprise an internal gear 16 on the drum 8 engageable by an idler gear 11 driven either by a pinion 10 coupled with the spindle 5 through a ratchet device 12, 13 or by an intermediate gear including a ratchet device and in mesh with a pinion 9 integral with the spindle 5. The reduction gear operable by rotation of the spindle in the same sense as the direct device, is over run when the direct device is selected. The normally operable unidirection means may comprise either pawls on the spindle and a ratchet on the drum or vice versa, the pawls being operated by means on the spindle or external thereto, or camming rollers between the spindle and drum.
