Abstract: A fuel injector is provided which includes a director, such as a ball, mounted downstream of the fuel injection port. When the valve is actuated, fuel exits the injection port. Fuel adheres to the ball until it reaches the equator of the ball. At the equator, the fuel begins to separate from the ball and forms a sheeted, cone-shaped configuration. When used with poppet valve injectors, the present invention preferably includes a wall manifold above the ball. Air from an air source, such as from the engine vacuum is introduced through the wall. Air travels through an air distribution chamber at a ninety degree angle to the direction of fuel flow. The air stream is directed to the ball's equator. This blast of air causes the fuel to atomize to a droplet size in the range of 3 to 6 microns SMD. When the invention is used with solenoid actuated fuel injectors, a ball is mounted downstream of the director plate. In this case, an air housing carries air from an air source to an air blast chamber.

Abstract: In FIG. 1, turbulent water or other fluid enters the nozzle body, 2, at inlet port, 1, and encounters the convex surface of a porous filter which has been formed into the shape of a hollow hemisphere, 3, at the center of which is the exit orifice. As the fluid flows through the hollow hemispherical diffuser it has its Reynold's Number significantly reduced. The energy of any gross turbulences on the convex side of the diffuser tends to be converted to a very great number of micro-turbulences which tend to be self canceling. Since the diffuser, 3, also shown in FIG. 3, is shaped as a hollow hemisphere centered upon the exit orifice, 4, then all water flowing from the diffuser to the exit orifice has substantially the same distance to travel from all directions. With this low-turbulence fluid all having substantially the same straight-line distance to travel to the exit orifice, 4, there tends to be little new turbulence introduced and the fluid, 5, exiting the orifice, 4, tends to be highly laminar.

A recess formed in the surface of the second deflector member facing the first deflector member provides a cavity which promotes atomization and generates turbulence.

Abstract: A simple, inexpensive container that may be a canister similar to an aerosol spray can is fixedly or pivotally mounted in inverted fashion above a cooking burner. The canister contains a particulate fire suppressant material and has a closable, downwardly-facing opening directed at the burner. A fusible or meltable material maintains a cap that covers the opening in the closed condition at all times except when a flame results from ignition of fat in a pan on the cooking burner.

The cap may be guided on a member having a stop at its lower end to capture the cap and prevent it from splashing into the fat upon ejection. Alternatively, the cap may be hinged to the container and be held in place at the hinge once the container is opened.
