Abstract

See full text

A unit fuel injector (30) has a reverse flow check (122) disposed in a circular reverse flow check cavity (124) to substantially close an exit through-passage (112) to the cavity which has a central axis (125) parallel to and spaced radially from a longitudinal axis (AX) of the unit fuel injector. The exit through-passage opens to the circular reverse flow check cavity at the central axis of the circular reverse flow check cavity. An adjoining cavity (131) distally adjoins the circular reverse flow check cavity. A passage (132) that at the adjoining cavity is radially off-set from the central axis of the circular cavity extends distally to a distal end of the spring cage.
