ABSTRACT:
Two embodiments of fuel injectors assemblies 10, 100 are disclosed. Injector (10) includes a fluid metering device (12) and a protective housing assembly (14). Device (12) includes an acoustic horn or nozzle assembly (16), a piezoelectric crystal (18) to longitudinally vibrate the nozzle, and a fuel inlet tube (20) rigidly fixed at one end (20a) to the nozzle and extending at the other end (20b) along an axis parallel to and radially spaced from the longitudinal axis of the nozzle. The protective housing assembly includes O-rings (52, 66) which vibrationally insulate device (12) from the housing and a fuel inlet 44 having a portion (44c) telescopically receiving tube end (20b) with an annular space therebetween. An O-ring (48) seals the annular space and allows relatively loss free longitudinal and radial movement of tube end (20b).
