Abstract: An air assisted fuel injector for an internal combustion engine includes a fuel nozzle having a fuel orifice and a targeting section cooperating with the fuel nozzle for targeting atomized fuel within the engine. An angled throttling section in disposed upstream of the targeting section and cooperates with the fuel nozzle. The throttling section throttles assist air prior to the air atomizing the fuel emerging from the fuel orifice and forms a vortex at the injector exit. Thus, any adverse effects on fuel flow from the fuel injector due to back pressure variability downstream of the fuel nozzle are reduced. In a preferred embodiment, an air shroud is fitted on the nozzle of the fuel injector and includes both the throttling section and the targeting section.

Abstract: A spray paint gun air stabilizing structure comprised in sequence of a connector, a valve, a shouldered tube, a spring and a piston. Wherein, the shouldered tube is provided inside the connector to accommodate the valve. A proper gap exists between the valve and the connector. The spring slips on the hollow piston. One end of the piston and its walls form two stopper walls compromising the inner diameter of the air passage of the spray paint gun while the other end of the piston penetrates through the shouldered tube towards the valve. Whereby, the pre-pressurized air in normal status drives the valve in the connector, then is introduced into the spray paint gun via the gap provided to the inner wall of the valve. If the air is over-pressurized, back-pressure is formed in the air passage to push the piston to compress the spring, the outer end of the piston gets closer to the end surface of the valve to narrow down the gap.

The device permits the permanent installation of spray nozzles on, in or near the surface intended to be protected by anti-icing agents. The device is easily maintained and left in a state of preparedness for use in the event of icing conditions. The invention provides a durable, adjustable and permanent point of attachment for spray nozzles for anti-icing purposes. The device may be surface mounted or embedded in an existing structure. Use of the device greatly increases the margin of safety for users of the driveways, sidewalks, etc.

Abstract: A fire extinguishing sprinkler nozzle includes a body defining a central channel or bore through which water flows during a fire. The sprinkler nozzle includes a fluid flow thrust reverser disposed over the orifice of the central channel such that water exiting out of the channel impinges the thrust reverser. The direction of water flow is reversed by the thrust reverser. After exiting the thrust reverser, the water impinges the impact surface of deflector disposed around the periphery of the sprinkler body. An upright sprinkler nozzle is thereby provided in which the water has a downward momentum prior to its impinging the impact surface of the deflector that is comparable to a pendent sprinkler head. The sprinkler nozzle is activated by conventional fire detecting or heat sensitive structures.
