  • Patent number: 6622932
    Abstract: Within an injector housing, a nozzle needle comprising a nozzle needle shaft is accommodated in a first guide boring in a longitudinally displaceable manner. A nozzle prechamber which is arranged in front of the nozzle needle shaft and which is situated on the fore-part of the first guide boring is supplied with fuel via a high pressure channel. A control valve permits a control chamber, which is coupled to the nozzle needle and which is subjected to the action of highly pressurized fuel, to be relieved from pressure by opening the nozzle needle. According to a second embodiment, a spring chamber is configured as a high-pressure chamber on the rear side of the first guide boring that guides the nozzle needle shaft. The spring chamber is separate from the control chamber and contains a readjusting spring that impinges upon the nozzle needle in a direction of closure. This configuration prevents fuel exiting the nozzle prechamber from overflowing over the guide boring which guides the nozzle needle.

  • Patent number: 6619569
    Abstract: The extended reach pressure relief spray valve mounts on the end of any length extension tube with any brand of spray gun or feeder valve. As the fluid is pumped through the spray gun and extension tube and into the spray valve, the pressure increases until it reaches an adjustable pressure relief set point (such as 1000 psi). At that point the valve opens and begins spraying. The relief spray valve doesn't require any long needles or cables to actuate the valve that results in a very simple extended reach pole gun. The relief spray valve opens by fluid pressure. Such fluid pressure can be easily adjusted by the user. The valve can be installed on any length pole. The spray relief valve is located next to the spray tip to minimize the paint from spitting and provides a sharp spray pattern. The spray relief valve is also built with a 180-degree swivel spray head for easy turn directional spraying.

  • Patent number: 6619559
    Abstract: An electronic scent-delivery system (10) is provided having one or more cartridges (100) filled with scented oil and maintained within pockets (53) of a tray (50) slidable within a tray support member (40) of a housing (20,30,60). Heating elements (76) are provided for indirectly heating the scented oil to an evaporative state, and acutating apparatus (92) are provided for engaging the cartridges to enable the scented evaporate to escape the cartridges. A blowing apparatus (86) provides an airflow over the tops of the cartridges, thereby directing the scented evaporate out of the housing through vents (65) in the housing faceplate (60) and into the surrounding environment.

  • Patent number: 6609665
    Abstract: A fuel injection valve for reducing carbon deposit on a passage portion between a seat portion and an injection port. The fuel injection valve includes an injection port 13 for injecting a fuel that is arranged to face a combustion chamber of an internal combustion engine. A seat portion H, where a valve element 8 comes in contact with a face of a valve seat 11 to intermit fuel injection, is arranged at a place upstream the injection port 13. The valve element 8 is conical at a portion downstream the seat portion H to an inlet of the injection port 13. The sectional area of the passage between the valve element 8 and the face of the valve seat 11 at the time of fully opening the valve element 8 is arranged so that the sectional area of the passage downstream of the vicinity of the seat portion H is larger. A tapered face 17 having a bore not more than 1/2.5 of an inner diameter of a swirl chamber 16 of a swirler 10 is formed on the face of the valve seat 11 which is downstream the seat portion H.

  • Patent number: 6565016
    Abstract: A head assembly is provided which is adapted to be connected to the output shaft of a motor. The assembly is used in providing a cloud of liquid wax for coating foodstuffs and includes a collector coaxially attached to the motor output shaft. An internal wall of a dispensing shroud surrounds the collector. A housing is attached to the motor and coupled to a liquid wax source. A delivery tube, which extends from the housing to the collector within the shroud, has an aperture at one end positioned in close proximity to the collector. The liquid wax flows down the tube to form a bead on the collector to be centrifugally dispensed against the internal shroud wall and to run down the shroud to be expelled as a mist.

  • Patent number: 6565021
    Abstract: A rotary atomizer with external charging which can be used for applying conductive paints, in particular water-based paint, to a surface of a body to be coated. The rotary atomizer has a directing air ring at a high-voltage potential and an earthed spraying bell. To reduce the risk of discharges, it is proposed to connect the ring to an earth potential via a high-impedance resistance, so that the ring assumes a potential which lies between the high-voltage potential of electrodes for the external charging and the earth potential of the bell.

  • Patent number: 6561439
    Abstract: A dual closure nozzle for use with a hose carrying a liquid under pressure. The dual closure nozzle is made up of an inner delivery conduit attached to an end cap and threaded within an outer sleeve. The nozzle is configured to have two different stop positions and to be adjustable between these two stop positions and a variety of open positions. When a liquid is forced through the nozzle, the flow of the liquid can then be adjusted from a first stop position, where no liquid passes out of the nozzle, through a variety of open position spray patterns to a second stop position. This configuration thus provides a nozzle that can be closed by turning the outer sleeve portion of the nozzle in either of two directions.

  • Patent number: 6561441
    Abstract: A kitchen-used sprinkling gun including a main body, a cap body and a switch unit. The cap body is clockwise and counterclockwise rotatably disposed on the main body. The cap body is formed with a central outlet section and a circumferential outlet section. The switch unit is disposed in the cap body. A spring serves to push a valve body to optionally seal one of two dividing holes of a water dividing disc. The two dividing holes respectively communicate with the central outlet section and the circumferential outlet section. A water generator is disposed between one dividing hole and the central outlet section. When a user turns the cap body, the water dividing disc is driven, whereby the flowing path of the water can be changed to discharge the water in different patterns.
