  • Patent number: 4440344
    Abstract: An injector for injecting fuel for an engine, which injector comprises a nozzle, a fuel injection orifice in a transverse face of the nozzle, a valve obturator for closing the orifice, a vibrator for vibrating the nozzle to cause the valve obturator to move away from the orifice to allow fuel to be injected, and a housing for the valve obturator, the housing: (A) being fixed in position, (B) having an open downstream end, and (C) being positioned adjacent the orifice but spaced apart from the transverse face of the nozzle by a distance which is not large enough to allow the obturator to escape through the space defined by the housing and the transverse face of the nozzle.

    Assignee: Eaton Corporation
    Inventor: Barrie J. Martin
  • Patent number: 4428531
    Abstract: A method of producing a fuel injector as herein defined, which method comprises securing the housing to an elongate member and securing the elongate member to the end of the injector remote from the orifice.

  • Patent number: 4345717
    Abstract: A low pressure fuel injection system for an engine, which system comprises an injector having a body, a fuel passage in the body, an outlet orifice, a valve obturator element, a spring which causes the valve obturator element to close the outlet orifice on its downstream side, and vibrator means for vibrating the injector to move the valve obturator element away from the outlet orifice to enable the fuel to pass through the outlet orifice.

  • Patent number: 4307838
    Abstract: An injector for injecting fuel for an engine, which injector comprises a nozzle, a fuel injection orifice in the nozzle, a valve for closing the orifice, a vibratory device for vibrating the nozzle to cause the valve to move away from the orifice to allow fuel to be injected, and a stop device for limiting the travel of the valve away from the orifice, the stop device being movable whereby during use of the fuel injector the injected fuel for the engine can be varied to suit the engine requirements at any given time by moving the stop device so as to control the travel of the valve injection rate through the orifice.

  • Patent number: 4276857
    Abstract: A boiler control system comprising an oil burner, one or more electrically-operated oil-injecting devices for injecting oil into a combustion chamber of the oil burner, and switch means for periodically energizing the or each oil-injecting device, and switch-control means for varying the ON/OFF time ratio of the energization of the or each oil-injecting device.

  • Patent number: 4251031
    Abstract: An arrangement for supporting a vibratory atomizer for liquids, in which a nozzle for ejecting the liquid forms the end of a longitudinal passage in a decreasing-diameter resonant vibration-amplifier horn that extends from a body portion equipped with a generator for longitudinal vibrations, in a supporting structure with a minimum of interference with either the longitudinal vibrations or radial vibrations which accompany these longitudinal vibrations. The atomizer is clamped axially between two annular resilient support members one of which acts upon a flange-like shoulder surface of the atomizer perpendicular to the longitudinal vibration at the larger-diameter base of the amplifier horn and permits relatively unrestricted radial movement of the shoulder surface, while the other engages the horn surface in the vicinity of this plane along a line at which the horn surface intersects a nodal zone of zero radial vibration, where it acts to centralize the atomizer in addition to supporting it axially.

  • Patent number: 4167158
    Abstract: Fuel injection apparatus comprising a fuel injector and a surface which can be vibrated, the apparatus being such that in operation the injector is vibrated to inject atomized fuel towards the surface which is also vibrated so that any particles of insufficiently atomized fuel can hit the vibrating surface and be further atomized.
