Abstract: An injection instant adjuster for internal combustion engines is proposed, by means of which the mutual rotary position of an off-drive element relative to a driving element is variable at least in accordance with rpm. The injection instant adjuster includes at least two adjusting cams acting as the adjusting mechanism, which during their rotary movements, effected by control elements, control a "late" adjustment (.alpha.) of the instant of injection during a first partial rotation (.gamma.) which precedes the "early" adjustment (.beta.) controlled during the further partial rotation (.delta.). This is possible by means of a suitable selection of the outset position of an adjusting bolt.

Abstract: An injection timing device is proposed for internal combustion engines, by means of which the mutual rotary position of the output shaft with respect to the input shaft can be varied in dependence on the speed and on at least one further operating parameter. The timing device comprises flyweights, operating in dependence on the speed against the force of resetting springs, and hydraulically operated control elements which engage the flyweights, these control elements, which are effective radially toward the outside, being accommodated within the timing element. By changing the position of the control elements, the radial position of the flyweights, which otherwise is determined only by centrifugal force, can be additionally varied in dependence on at least one further operating parameter of the engine, preferably the load, in order to correct the instant of injection.

Abstract: An injection timing device is proposed for internal combustion engines, by means of which the mutual rotary position of the output shaft with respect to the input shaft can be varied at least in dependence on the speed. The timing device comprises at least one pair of eccentrics which serve as the adjusting gear system and comprises an adjusting eccentric and a compensating eccentric, this pair of eccentrics being supported in a bearing member connected to one of the shafts, the adjusting eccentric of this pair also being coupled by means of a transmission member with a hydraulically operable servo piston. By a positional change of the servo piston effected by the hydraulic medium, the adjusting eccentric can be rotated to change the instant of injection.

Abstract: Sections of a bus bar stack are coupled together with insulating spacers between bars of different potentials, by a clamping device that embraces the stack, thereby avoiding the need for cutouts in the bars at the coupled junction. The form of the clamping device may be a U-shaped bracket encompassing the stack and having adjustable clamping means mounted on the leg ends for applying resilient clamping pressure on the stack through a pressure member bridging between the bracket legs. Alternatively, a support on one side of the stack and a clamping element spaced from the support are joined by levers. Adjustable clamping means on the ends of the clamping element apply clamping pressure on the stack through the levers. The support may form part of an enclosure for the bus bars and may include an insulated tray having offset slots for supporting the coupled bus bar sections in desired relation to each other.
