Abstract: A typical solenoid-operated fuel injector comprises a housing forming an enclosure which contains a solenoid coil that is selectively energized by electric current to operate the fuel injector. An inlet connector tube extends into a stator to convey liquid fuel into the enclosure, to a valve via which fuel is ejected from the enclosure. A valve needle is disposed within the enclosure between the stator and the valve and is operated by the solenoid coil acting through a spring-biased armature to open and close a flow path through the enclosure between the inlet connector tube and the valve. The stator forms a portion of a magnetic circuit path that directs magnetic flux across a working gap that is disposed within the enclosure between an end of the stator and on one side of the armature wherein the one side of the armature causes impact forces to be exerted axially on the stator during the opening and closing of the flow path.

Abstract: A gardening-used variational sprinkling head with fully discharging openings, composed of a variational water-discharging cover and a base member associated therewith. The sprinkling head is associated with a sprinkling gun. The sprinkling gun has an inner water outlet. The water-discharging cover is formed with radial ribs inward projecting from inner periphery thereof to define several fully discharging openings. A circular mesh plate is placed within the radial ribs. Six different variational sprinkling holes and two close holes are integrally annularly arranged on a central portion of the mesh plate. The six variational sprinkling holes respectively have six rearward extending hollow posts which respectively abut against six water inlets annularly arranged on the base member. The base member is connected with the mesh plate by ultrasonic fusion and spaced from the radial ribs by a space so that water can pass through the fully discharging openings.

Abstract: An improved portable fueling facility for aircraft or ground vehicles includes, in the disclosed embodiments, at least one storage tank, an outer tank for providing secondary containment about the storage tank, a number of saddle members for supporting the outer tank on a flat horizontal surface, and a pump for dispensing fuel. In one embodiment, a system is provided for suppressing combustion that might otherwise occur within the storage tank. To minimize heat transfer from outside the facility into the storage tank, fire-retardant insulation material is positioned between the storage tank and the outer tank. In addition, a heat sink may be positioned between the two tanks to intercept heat that would otherwise flow to the storage tank.

Abstract: An apparatus disposed within a pressurized container for enabling product contained in the container to be dispensed at a predetermined constant pressure, which apparatus includes a vessel having first and second enclosures housing pressurized gas and a member exposed to the pressure in the container. Fluctuations of the pressure in the container cause the member to move to a first position when the pressure in the container equals the predetermined pressure and to a second position when the pressure in the container is below the predetermined pressure. Pressurized gas passes from the first enclosure to the container when the member moves to the second position, the passage of which is prevented when the member moves back to the first position.

Abstract: Apparatus and methods for making uniformly-sized and predictably-spaced droplets from high-temperature liquids. Liquid droplet generators having electromechanical driving elements are coupled to a power supply to apply pulsed excitation forces through a wall of a delivery tube to a high-temperature liquid, e.g., a liquid metal, epoxy, or polymer. The excitation forces generated by the driver induce capillary vibrations in the liquid within the delivery tube. Liquid jet streams having capillary vibrations when exiting an orifice break up into groups of substantially uniformly-sized liquid droplets shortly after leaving the orifice. Droplets may be produced in a uniformly-spaced series, or individually on demand in response to a single burst of force from the driving element. A heat source is also thermally coupled to the delivery tube to maintain the liquid in a high-temperature state.

Abstract: Orifice elements for use in valves for injecting fuel or a fuel-gas mixture. The orifice elements include two silicon plates, joined to one another. An upper plate has one or more injection orifices. The lower plate has a through hole introduced in it, through which a fuel jet can emerge. The lower plate follows in the downstream direction and includes a jet splitter. The jet splitter divides the through hole into at least two passthrough openings so that a dual-jet characteristic is produced or maintained for the valve. At least two conduits are formed between the upper plate and the lower plate. Gas is provided via the conduits and is mixed with the fuel discharged through the injection orifice. The injection orifice and the valve are particularly suited for injection systems of mixture-compressing internal-combustion engines having externally supplied ignition.

Abstract: An apparatus for measuring and displaying a time interval between a valve closure and subsequent termination of a flow at a spigot is provided. The apparatus has magnetic sensors coupled to a flow regulating valve for providing a signal indicative of a solenoid-activated valve closure and detectors for determining fluid flow. The detectors have an infra-red light source and associated photo-sensor mounted near the water outlet spigot such that when a fluid flow is present at the spigot, the fluid reflects light from the infra-red light source so that the associated photo-sensor provides an output signal. A differential amplifier compares the photo-sensor output signal with a constant to determine a water run condition. Logic circuitry is connected to the comparison signal output to provide a timer actuation. The timer measures and displays the time interval between a valve closure and subsequent termination of flow at a spigot. The apparatus may be embodied as a hand-held or stationary unit.
