Abstract: An injector is disclosed which comprises a valve needle engageable with a seating. A spring urges the needle towards its seating, the spring engaging a spring abutment. A pressure backing member positioned within the injector is slidable relative to the spring abutment under the action of the pressure of fuel applied thereto. The pressure backing member is engageable with a surface associate with the needle to urge the needle towards its seating. The slidable pressure backing member reduces the pressure in the pumping chamber both prior to and after termination of the injection process. Also, the backing member maintains the pressure in a fuel supply passage of a low level to enhance the efficiency of the injector.

Abstract: The fire suppression system includes a system piping, with at least one sprinkler, a flow control valve, a fire suppressant delivery line in fluid communication with the flow control valve, at least one fire detector adapted to detect temperatures associated with fire, and a control system. The control system is in communication with the fire detector, the flow control valve and the system piping. The control system is adapted to detect a flow condition and a no-flow condition in the system piping and actuates the flow control valve between a normally open condition and a closed condition when the fire detector is in a no-fire condition state and the control system detects a flow condition in the piping system and may cycle the flow control valve to open when the flow control valve is closed in response to the fire detector being in a fire condition state.

The extinguisher can also be mounted and provided with a heat sensor for automatic activation.

Abstract: A nozzle for dispensing a liquid or semi-liquid substance (P) and designed to be mounted on a tank (R) suitable for being put under pressure. The nozzle is of the type comprising a thimble (1) and moving shutter (2) housed inside the thimble. The thimble (1) is provided with a coupling end (11) for coupling to the tank (R) and an ejection orifice (10). The shutter (21) is constituted by a rod (21) carrying a plug (20) at an outer end thereof. The plug (20) cooperates with the ejection orifice (10) to form a delivery valve. The rod (21) also carries a transverse wall (22) at an inner end thereof. The wall (22) leaves a passage for the substance (P) and cooperates with a resilient return means (3) for returning the moving shutter (2) towards a closed position in which the plug (20) is engaged in sealed manner in the ejection orifice (10).

Abstract: An electromagnetically actuatable valve, including a connecting piece, which is connected to an armature. The valve needle has a connecting piece with a circular cross section with an armature head formed by cold forming in which the armature head is welded together with the armature. The valve needle permits a weight reduction and therefore a more rapidly closing valve. The valve needle is particularly suited for injection valves in fuel injection systems of mixture compressing internal combustion engines with externally supplied ignition.

Abstract: A proximity detecting system for use with an agricultural equipment or implement such as a crop sprayer, for determining the position of the implement, e.g. the end of a spraying boom relative to the edge of the previously cultivated or sprayed area. The system has an electronic imaging device, e.g. a CCD array, mounted at the end of the implement or sprayer, which shows the location of a marker placed at the edge of a previously cultivated or processed swath. The position of the marker is shown on a visual display located in the operator's cab. A deviation of the marker from a predetermined position on the display alerts the operator of an overlap with, or miss, of the boundary of the previously processed swath.

Abstract: Present fuel injectors fail to be cost effective and with the complexity of recent fuel injectors tend to be labor intensive. The present fuel injector and method of making the fuel injector provides a cost effective fuel injector which reduces the labor intensiveness of manufacturing. The manufacturing of the fuel injector includes the separate formation of a first unitary component, a second unitary component and a third unitary component by individual castings. The unitary components are positioned relative one to another and welded forming the fuel injector having a preestablished configuration. The unitary components are individually cast and each include an as cast complex configuration verses a plurality of individual components being welded in subassemblies and into a final assembly.

Abstract: The invention provides a combination of a nozzle and a vacuum hood. The vacuum hood has a chamber that surrounds the tip of the nozzle and removes residue from the tip by a vacuum which flows in the chamber past the nozzle tip. This vacuum catches and removes residue from the nozzle tip and prevents the reside from interfering with the spraying action or dripping down. The method of the instant invention provides for dispensing a fluid from a nozzle without dripping fluid from the nozzle having a vacuum hood. The method comprises: (a) dispensing a fluid on a rotating semiconductor wafer through a nozzle over the wafer; (b) terminating the fluid flow through the nozzle; (c) creating an upward flow of gas about the dispensing nozzle when the flow of fluid through the nozzle is terminated; (d) capturing any fluid residue from the nozzle in the upward flow of gas; (e) removing the wafer and positioning another wafer; and (f) terminating the upward flow of gas; and repeating the process of steps (a) through (f).

Abstract: In a first preferred embodiment for an improved synthetic jet actuator, the orifice shape is altered by either a flap or adjusting the housing walls. If the flap is deployed outward from the wall just above the orifice of a synthetic jet actuator, the synthetic jet flow will be vectored upward, toward the flap. Similarly, if the upper wall forming the orifice is moved outward from the jet chamber interior with respect to an opposing wall forming the orifice, the flow will also vector upward. In the second preferred embodiment of an improved synthetic jet actuator, an opening in addition to the orifice, may be formed in one or more walls of the housing. A louver is aligned with the opening in the housing and permits fluid flow in only one direction, either into the chamber or out of the chamber. When the louver permits fluid flow into the chamber, the jet actuator can operate at high speeds since fluid can enter the chamber through a greater surface area.

The manifold (50) is connected to receive water which is supplied to the sprinkler head through the water supply conduit.

Abstract: A fuel injection valve for internal combustion engines, having a valve member that is guided so that it can slide axially in a bore of a valve body.

In order to control the two-stage opening stroke course of the valve member, the adjusting member is embodied as an adjustable stop, in which the valve member comes into at least indirect contact with after passing through a partial stroke and which in a first position, is locked in its initial position and in a second position, can be moved in the opening direction by means of the valve member.

Abstract: A fuel injector for effectively preventing excessive loading of a component mounted internal to the injector is provided which includes a one-piece retainer having first and second connector portions for permitting two independent loads to be applied to different internal components of the injector. The second connector portion includes threads for engaging a nozzle assembly to impart a compressive force on the nozzle assembly. The first connector portion also includes threads for engaging an outer barrel for placing a first compressive load on a load sensitive internal component, such as a center tube of an injection control valve. In this manner, the second compressive force can be set at a minimum level independent from the first compressive force to permit the size of the center tube to be minimized thereby reducing the overall size of the injector.
