Abstract
A fuel injection pump of the rotary distributor type includes a rotary distributor member having a bore in which is slidable a plunger which can be actuated by a cam lobe. A stop ring is provided to limit the outward movement of the plunger by fuel which is supplied to the bore through an inlet passage in the distributor member when the latter is in register with an inlet port. The stop ring has a surface which will permit further outward movement of the plunger following cessation of fuel flow through the inlet port and passage and such additional movement to allow an excess of fuel to be delivered is allowed by fuel flow through an additional inlet passage. This passage is controlled by valve means which is preferably only opened when the engine is at rest.
