A delivery valve includes a body defining a chamber into which from one end thereof extends a tubular support member. The interior of the member is connected to the outlet of a fuel pump and an outlet extends from the chamber to a fuel nozzle. Slidable about the support member is a first valve element which defines a seating in its end presented to the other end of the chamber. A second valve element is provided for engagement with the seating and a spring urges the first valve element into engagement with the second valve element. The first valve element also defines a surface against which the fuel pressure in the interior of the tubular member can act to lift the first valve element away from the second valve element to allow fuel flow from the outlet.

[ What is claimed is:] [1.] A delivery valve for incorporation in a fuel injection line connecting an outlet of a fuel injection pump with a fuel injection nozzle of a compression ignition engine, the delivery valve being adjacent the outlet of the pump, and including a body defining an elongated chamber, an outlet extending from the chamber and being connected to the end of an injection line adjacent the pump, a tubular support extending into the chamber from one end thereof, the interior of the support member being connected to the outlet of the fuel injection pump, a first valve element slidably mounted on the support member, an annular seating defined on the end of the valve element remote from said one end of the chamber, a second valve element shaped for engagement with the seating, resilient means biasing the first valve element away from said one end of the chamber, first stop means acting to limit the movement of the valve elements under the action of the resilient means, second stop means engageable by the second valve element to limit the movement of the second valve element towards said one end of the chamber and said first valve element defining an area which is exposed to the fuel pressure within the tubular support member.
