ABSTRACT:
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.
