An atomizer for use with a combustor in a gas turbine has a body with a fuel passageway extending through the center of the body. A plurality of channels extends within the body about the passageway centerline, and are oriented along a circumferential angle about the passageway centerline to deliver air at the discharge end of the passageway with an axially whirling motion. The channels are simultaneously oriented along an axial angle about the passageway centerline, thereby directing the flow of air to converge toward the passageway centerline, mix with the fuel, and then at least in part diverge from the passageway centerline. The whirling air intersects with the fuel at the exit of the nozzle to effectively atomize both the air and fuel thereby providing a homogeneous air/fuel mixture to the combustion chamber.

The device according to claim 1 wherein: the handlebar extends from bars which extend upwardly from the housing unit, the bars being swivel-mounted on the housing unit so as to allow an operator move the handlebar to and from its operating and non-operating positions, respectively. 3. The device according to claim 2 wherein: at least one of the bars contains an aperture extending along the longitudinal axis thereof. 4. The device according to claim 3 wherein: the locking mechanism is connected with the at least one of the bars and includes a pin connected thereto, the pin protruding through the aperture to permit the locking mechanism to move with the handlebar as it is placed in either its operating or non-operating position. 5. The device according to claim 4 wherein: the locking mechanism includes a substantially disc-shaped portion. 6. The device according to claim 5 wherein: the disc-shaped portion includes at least one projection on a side thereof. 7. The device according to claim 6 wherein: the locking mechanism further includes an axle connected with the housing portion and having attached thereto a collar portion, the collar portion being engageable with the at least one projection to assist in locking the handlebar in its operating position upon movement of the handlebar thereto. 8. The device according to claim 7 wherein: the actuator includes a compressible trigger mounted with the handlebar. 9. The device according to claim 8 wherein: the actuator further includes an extensible cable having first and second ends, the first end thereof being attached with the trigger and the second end thereof being connected with a spring-loaded engine brake to either allow or disallow operation of the engine and/or the member powered thereby upon movement of the actuator. 10. The device according to claim 9 wherein: the cable is housed by a cover along a portion thereof, the cover having first and second ends through which the cable extends, the first end being connected with the handlebar and the second end being connected with the collar portion. 11. The device according to claim 10 wherein: the collar portion is arranged alongside the disc and is positioned to share an axis passing through the disc and which is transverse to the longitudinal axis of the bar on which it is mounted. 12. The device according to claim 11 wherein: the collar portion is pivotally attached to the cover so as to allow it to move throughout a range of motion traveled by the handlebar. 13. The device according to claim 12 wherein: as the handlebar is moved into its non-operating position, the at least one projection on the disc move towards the rear of device and away from the collar portion. 14. The device according to claim 13 wherein: when the handlebar is moved into its operating position, the at least one projection on the disc are positioned towards the front of the device and towards the collar portion whereby it is received by the collar portion. 15. The device according to claim 14 wherein: the collar portion is loaded by a spring associated with the cover and which abuts against the collar portion, movement of the handlebar rearwardly of the housing unit to its operating position rotates the disc rearwardly so as to cause the collar portion to receive and embrace the at least one projection. 16. The device according to claim 15 wherein: compression of the trigger towards the handlebar causes the pull cable to become stretched whereby the cable presses against the cover to cause the collar portion and the cover to move together, whereby the collar portion remains embraced with the first projection and abuts a gainst a second projection adjacent the first projection so as to prevent further movement of the collar portion and thereby lock the handlebar into the operating position. 17. The device according to claim 15 wherein: compression of the trigger in the operating position relieves the spring force of the engine brake so as to permit operation of the engine and the member powered thereby when the handlebar is locked in the operating position. 18. The device according to claim 17 wherein: the spring force on the engine brake surpasses the force emitted by the spring acting on the collar portion resulting in the application of the engine brake with respect to the engine even in the presence of compression of the trigger towards the handlebar so as to draw up slack present in the pull cable. 19. The device according to claim 13 wherein: the collar portion is loaded by a spring associated with the cover and which abuts against the collar portion, movement of the handlebar forwardly relative to the housing unit rotates the disc forwardly so as to move the projections associated with the disc away from the collar portion. 20. The device according to claim 2 further comprising: an axle pivotally connected between the bars, the locking mechanism being connected with the axle so as to be moveable therewith as the handlebar is moved between the operating and non-operating positions. 21. The device according to claim 20 wherein: the locking mechanism includes a substantially disc-shaped portion attached with the axle. 22.
