A liquid fuel injection pump of the rotary distributor type has a first groove on the distributor member for registration with fuel supply ports and a second groove for registration with outlet ports. The grooves are connected to the plunger bore and as the distributor member rotates fuel is supplied to the bore through the first groove and delivered to an outlet through the second groove. The distributor member is axially movable to control the quantity of fuel delivered and in the excess fuel position the second groove is arranged to register with a vent port during the initial period of registration of the first groove with an inlet port. This allows air to be purged from the passage and bore. |
