  • Publication number: 20200086438
    Abstract: There is provided a method for aligning a spindle of a machine tool, the spindle having a longitudinal axis and being rotatable about the longitudinal axis. A trial mounting of the spindle is performed, comprising mediately or directly attaching a bearing surface of the spindle to a support surface of the spindle housing. An actual deviation of the spindle is detected. A wedge-shaped adjustment disc is selected, depending on the detected actual deviation. The adjustment disc is arranged between the bearing surface of the spindle and the support surface of the spindle housing in a defined rotation orientation so that the adjustment disc at least partially corrects the actual deviation.

  • Patent number: 7920957
    Abstract: A method for metering fuel into a combustion chamber of an internal combustion engine is provided, in which a fuel quantity to be metered for a combustion is metered by a preinjection and at least one additional injection, and in which, in the operation of the internal combustion engine, quantity errors of the preinjection are ascertained from the signal of at least structure-borne noise sensor. The method is distinguished in that a correction value is formed as a function of the quantity error of the preinjection, and at least one of the additional injections is corrected using the correction value. A control device is also provided that controls the method.

  • Patent number: 7891587
    Abstract: The invention relates to an intermediate plate for a fuel injector, comprising a high-pressure through-hole which connects a high-pressure passage in a valve body and is connected to a high-pressure fuel reservoir, to a high-pressure space in a nozzle body, wherein the intermediate plate is arranged between the valve body and the nozzle body. In order to improve the injection behaviour of a fuel injector provided with the intermediate plate, in particular during multiple injection of small injection quantities, the high-pressure through-hole has a cross-sectional profile which improves the flow through the high-pressure through-hole from the valve body towards the nozzle body and impairs the flow in the opposite direction from the nozzle body towards the valve body.

  • Publication number: 20090108093
    Abstract: The invention relates to a fuel injector having an injector housing which has a high-pressure fuel connection which is connected outside the injector housing to a central high-pressure fuel source and inside the injector housing to a pressure space. From the fuel injector highly pressurized fuel is injected into a combustion chamber of an internal combustion engine as a function of the pressure in a control space when a nozzle needle opens In order to provide a fuel injector which can be manufactured inexpensively, the pressure in the control space is controlled directly by a magnetic actuator.

  • Patent number: 7347389
    Abstract: A fuel injection valve for internal combustion engines, having a valve body with a bore defined on its end toward the combustion chamber by a conical valve seat, with a valve needle disposed longitudinally displaceably in the bore and a sealing face with two sealing portions on its end toward the combustion chamber with the second conical face being disposed on the combustion chamber side of the first conical face. An annular groove extending between the conical faces has an end facing away from the combustion chamber which acts as a sealing edge upon contact of the valve sealing face with the valve seat. Recesses embodied in the valve seat and/or on the valve sealing face hydraulically connect the annular groove with a portion of the second conical face located on the combustion chamber side of the annular groove.

  • Patent number: 7093586
    Abstract: A method for controlling a fuel metering system of an internal combustion engine. A activation duration of at least one electrically operated injector determines the injected fuel quantity. The minimum activation duration during which fuel is only just injected being determined in certain operating states. The activation duration being increased/reduced starting at an initial value, and the activation duration during which a signal undergoes a change being stored as the minimum activation duration, in which the difference between the activation duration during which a signal undergoes a change and the stored minimum activation duration is determined, from which correction values for the fuel quantity map of the injector are determined and stored using at least one transfer function, which characterizes the relationship between the minimum injection and activation durations at several test points of the injector and/or the relationship between the activation durations at different test points of the injector.

  • Publication number: 20050206205
    Abstract: The invention involves a two-piece seat for a passenger-carrying vehicle with the seat being capable of complying with the federal requirements with reduced complexity. A steel plate is rigidly attached to the rotating seat back. The steel plate will prevent the seat back from rotating during normal use. If the bus were in a collision, a belted occupant would apply load to the rotating seat back through the seat belts. The steel plate would deform, allowing the rotating seat back to come forward. The fixed portion of the seat back remains in position to act as a passive restraint for any passengers seated behind this particular seat. Utilizing deformable steel plates to retain and control the operation of a rotating seat back equipped with 3-point restraints is a unique aspect to this invention. The plates will retain the rotating seat back in normal use to prevent vandalism to the seat belts, and can be easily removed so the seat back can be rotated forward for servicing the seat belts and upholstery covers.

  • Publication number: 20050200172
    Abstract: The invention involves a seat system with a movable and immovable portions that may be maintained and still operate during transients as required under the federal regulations. There is a quick release serviceability latch for a school bus passenger seat with integrated restraints. The inner and outer seat backs must be quickly detached from one another to facilitate repair or replacement of damaged seat components. A movable plunger is rigidly attached to the inner seat back frame. Another bracket with hole to accept the plunger is rigidly attached to the back pan of the outer back. The attachment of inner to outer seat backs must be strong enough so that they can't be pulled apart by hand but at the same time be detachable in the event of a crash. A tab that engages the plunger separates upon a rapid deceleration event.

  • Publication number: 20050189801
    Abstract: A vehicle passenger seat active occupant restraint provides for absorbing energy from a passenger during sudden deceleration of a vehicle. The torso belt portion of a three-point restraint system is anchored using a spring and a displacement limiting linkage at the opposite end from its point of connection to the lap portion of the belt. During deceleration energy is transferred from the restrained occupant to the spring up to the displacement limit.

  • Publication number: 20050189800
    Abstract: The invention involves creating a thinner structured seat capable of complying with the federal requirements. The steel back pan is rigidly mounted on three edges to the back frame seat structure. The bottom of the back pan is unformed and allowed to flex in the fore-aft direction. The back pan is then covered with foam that may be one third as thick at the bottom as to thickness at the top of the back pan. The three to one ration of the lower to upper portion for the foam is important in achieving seat thinness. When seat spacing is measured at the h-point or cushion level, the knee protection zone is thinner than conventional seats and allows for a greater number of seats to be placed into a school bus. Utilizing a flexible steel back pan combined with foam in the proper ratios to absorb energy in the knee protection zone through the upper portion achieves the invention.
