  • Patent number: 6431474
    Abstract: An electromagnetically operable fuel injector for a fuel injection system of an internal combustion engine is disclosed having a ferromagnetic core, a magnetic coil at least partially surrounding the ferromagnetic core and an armature magnetically coupled to the magnetic coil and being movably responsive to the magnetic coil. The armature actuates a valve-closing element, which interacts with a fixed valve seat and is movable away from the fixed valve seat of a fuel valve when the magnetic coil is excited. The armature has a generally elongated shape and a generally central opening for reception of fuel from a fuel inlet connector positioned adjacent thereto. The fuel inlet connector extends in a generally longitudinal direction above the armature and defines a central path for fuel to enter the inlet connector and to be directed toward the armature for further passage toward the fixed valve seat.

  • Patent number: 6375094
    Abstract: A spray gun includes a handle portion and an extension portion. A nozzle is connected with an outer end of the extension portion. An electrode assembly is disposed in the extension portion to establish an electrical field to electrostatically charge particles of coating material. A coating material flow control member and a purge air flow control member are disposed on the handle portion. Operation of either one of the two flow control members actuates a membrane switch assembly. Operation of the purge air flow control member directs the flow of air to the coating material passage in the extension portion to remove excess coating material from the passage and from the nozzle. Different size hand grips may be mounted on the handle portion of the spray gun to accommodate operators having hands of different sizes.

  • Patent number: 6367719
    Abstract: The present device provides a fuel injector including a two-input, self-triggering monostable driver circuit for an electromechanical valve is disclosed. Upon receipt of an initiation signal, the driver circuit generates a predetermined current profile in a coil. A current sensing mechanism senses the current flowing through the coil, enabling a current threshold generator to detect a preset peak current threshold state. Upon detection of the preset peak current threshold state, the current threshold generator establishes a new hold current threshold state in the coil. A rapid decay generator forces a rapid transition from peak current to hold current within the coil. The hold current is maintained within preset hysteretic limits until the valve cycle is terminated by removing the initiation signal from the inputs.

  • Patent number: 6311902
    Abstract: A nozzle for substantially laminar dispersion of gases at an angle to a central axis has a conically shaped portion and a stem portion. A chamfered bore allows a smooth entry of gas or vapor under pressure into a longitudinal bore within the stem portion which extends into the conical portion. A plurality of angularly oriented bores extend from the sloping face of the conical portion into the longitudinal bore forming sharp ridges at their intersection with the longitudinal bore, with the centerlines of the angular bores, all intersecting within the longitudinal bore. The conical portion is truncated and an axial bore extends from the truncated portion into the longitudinal bore. The diameters of the angular bores, the axial bore, and the longitudinal bore are chosen to insure the formation of sharp ridges to the exclusion of flat surfaces or lands.

  • Patent number: 6302336
    Abstract: A watering container with a rotatable nozzle having a plurality of water delivery patterns. In particular, a rotatable nozzle having a plurality of water delivery patterns is rotationally attached to a water spout on a watering container. A user can turn the rotatable nozzle to select the desired water delivery pattern. In a preferred embodiment of the watering container, the user may select either a steady stream water pattern or a dispersed rosette water spray pattern. The watering container includes an internal fluid reservoir which can vary in volume based on the needs of the user. Water exits the internal fluid reservoir and flows through the water spout and then through the water delivery pattern selected by the user on the rotatable nozzle when the watering container is properly tilted. An integral elongated handle on the watering container enables the user to reduce stress on their hand and wrist during the tilting process.

  • Patent number: 6257462
    Abstract: The present invention is a self-measuring container that dispenses only a specific amount of fluid each time fluid is poured from the container. This container has a storage chamber where the fluid initially resides and a measuring/dispensing chamber, below the storage chamber, where the specific amount of the fluid that will be dispensed during the next pouring operation resides. An aperture at one end of the container connects the storage and dispensing chambers. This aperture permits the fluid in the storage chamber to flow into the dispensing chamber. The container dispenses the fluid through an exit channel that extends from the dispensing chamber to the top of the container. The storage chamber bottom serves to separate the storage and dispensing chambers and acts as a barrier during a pouring operation to prevent fluid from flowing from the storage chamber to the dispensing chamber until desired. The measuring chamber may also contain a diaphragm to permit the volume within the chamber to be adjusted.

  • Patent number: 6247655
    Abstract: A fuel injection valve for internal combustion engines, with a valve member which is guided axially displaceably in a bore of a valve body and which has, at its end on the combustion space side, a conical valve sealing face, the conical valve sealing face cooperates with a conical valve seat face at that end of the bore on the combustion space side. A blind hole or a conical region adjoins said bore on the combustion space side, with a pressure space that opens onto the valve seat and located between the valve member shank and the wall of the bore, and with at least one injection duct which leads from an inner wall of the injection valve. The inner wall being located downstream of the valve seat. To form the injection jet, the entry regions of the injection duct are rounded, an upper entry region which faces the pressure space having a large radius (RA) and a lower entry region which faces away from the pressure space having a smaller radius (RB). At the same time, the size of the radius (RA) is 0.02 to 0.

  • Patent number: 6244522
    Abstract: A dispensing head for air assisted and airless application of a material to a surface includes a cylindrical barrel having a supply passage therein for the material to flow from a source to a nozzle. The barrel includes at one end a nozzle seat that slideably receives a nozzle body. The nozzle body has a bore that opens at one end to the barrel passageway, and at another end has a nozzle tip with an orifice through which material is dispensed. The nozzle body has a groove formed therein that receives a seal. When the nozzle body is inserted into the nozzle seat, the seal is compressed between the nozzle groove wall and a wall of the nozzle seat to hold the nozzle within the nozzle seat during further assembly of the dispensing head. The seal is preferably captured and isolated from a set of air jets that are formed in the nozzle body, thereby preventing the seal for blocking the air jets.
