The distributor has a distributor rotor with a radially extending rotor electrode attached nonrotably to a drive shaft, a distributor cap provided with a number of connectors on top each having a through-going opening in an interior wall of the cap, a center electrode insertable through the center connector in the cap and distributor electrodes insertable through peripherally disposed connectors so that they are positionable spaced from the rotor electrode during rotation of the distributor rotor past them, connecting cables each of which are connected to an electrode for conveying ignition energy to a spark plug and retaining members each releasably holding one of the distributor electrodes in place in the cap. The free end of one of the electrodes may be serrated or knurled while its other end together with the connected end of the connecting cable is enclosed by a lip member made of an elastic insulating material, in which one of the connectors is insertable and tightly held.

Distributor for an ignition system of an internal combustion engine

Ignition device for internal combustion engines

The control generator of an ignition distributor for a transistor-coil ignition comprises an annular coil (55), a rotor (54) and a stator, which is a riveted unit comprising a stator plate (18), a permanent magnet (17) and a pole disc (56). The rotor and the pole disc are molded elements of sintered iron or of a mixture of sintered iron powder and carbonyl iron powder having a binder of thermosetting resin. The rotor and the pole disc have cooperating pole teeth (59,51), which are directed parallel to the axis (60) and whose cross section is triangular, with the triangular tips oriented toward one another. These 'pointed teeth' produce a more steeply inclined signal course, as a result of which a decreased inherent shifting of the inductive transducer, and thereby more reliable starting of the engine, are attained.

Ignition distributor for internal combustion engines

An injection-molded cast aluminum base shell, open at the bottom and having individual openings at the top through which respectively protrude a part of the ignition transformer and a part of the transistorized circuit unit, in each case for external connections, consolidates enough of the circuit components to provide an assembly that can be mounted in an accessible portion of the motor compartment of a vehicle on the vehicle body structure to facilitate comprehensive maintenance attention.

To provide for fine adjustment of the timing of operation of the ignition breaker switches, the breaker plate is connected by an adjustable link to a vacuum ignition control diaphragm, the link being a two-element unit, one element having a right-hand thread at the end and the other a left-hand thread, coupled by a coupling element rotatable in both said right and left-hand threads to shorten or lengthen the overall length of the link. The coupling element is externally accessible, for example by means of an additional transmission wheel or gear.

Ignition distributor-circuit breaker assembly for internal combustion

To reduce the axial length of distributor-breaker assemblies and to provide for reliable placing of a second upright bearing for the distributor shaft, a holding plate to which a bearing is floatingly attached is clamped in the distributor housing by means of a claw clamp, tightened by a transverse plate against itself and against a shoulder formed in the inner side wall of the distributor, the claw clamp being formed as a partly circumferential ring seated in a groove of the distributor.

Ignition distributor-breaker structure for internal combustion engines

To prevent corrosion and provide for better relative movement of parts which move only slightly but are exposed to extremes in ambient operating conditions, a tubular piece of plastic material, typically Polyvinylidenfluoride or a polyamide, is drawn over the inner element of a relatively slidable pair, which may, for example be a distributor shaft, the distributor breaker cam, or distributor bearing pins, to cover the surface thereof engaged in slidable contact.

Method of making distributor assembly bearing structures and the like

Four pole pieces embedded in the cylindrical periphery of a non-magnetic rotor disk are connected with each of a number of magnets embedded in the disk in circumferentially distributed positions spaced from the rotor shaft and from the disk periphery. Of these pole pieces, one circumferentially interleaved pair is connected with one pole of the magnet by a magnetically conducting yoke strip embedded in one circular face of the disk and the other pair is similarly connected with the other pole of the magnet. The spacing between the first and second pole piece is equal to the spacing between the third and fourth and less than that between the second and third, the latter spacing being equal to the spacing between groups of pole pieces associated with different magnets, for the case of a uniformly timed firing sequence of a multicylinder engine.

To provide an easily manufactured ignition distributor in which two bearings support the distributor shaft, the lower bearing is molded or otherwise secured into the housing structure, whereas the upper bearing is supported on a transversely extending support member, typically a support plate which is seated within the housing, for example bearing against a shoulder, against seating lugs, or the like, so that the entire ignition distributor structure can be constructed with small compact size.
