ABSTRACT:
A unit injector (2) of the cam actuated, open nozzle type is disclosed in which an extremely compact injector body (4) has a minimum number of internal flow passages (66, 72) designed to reduce the complexity and cost of manufacture of the injector. The invention is characterized by an injector body (4) having an exterior shape designed to form a fuel supply flow path (22) and an isolated fuel drain flow path (24) between the exterior surface of the injector body (4) and the interior surface of the recess (6) in which the injector (2) is designed to be received. This arrangement allows a very simple pattern of radial passages (66, 72) to be formed in the injector body (4) even through the injector (2) is designed to provide scavenging fuel flow previously requiring a much more complex injector design.
