  • a jaw-like contact breaker assembly module is remov- France 7102815 able from a distributor housing allowing ease in Jan.
  • a make-and-break support of thekind according to the invention is also of use for controlling a fuel injection pump supplying the cylinders of the engine with which such a pump is associated.
  • the required pulse timing it is known for the required pulse timing to be achieved by having the pulses produced by means of a contact breaker (make-and-break) device actuated by a cam on the shaft of the ignition distributor associated with the engine, the'same rotating the shaft; it is another object of this invention to disclose means for making independent of one another, on the one hand, the ignition distributor elements for producing the high-voltage current for engine ignition purposes and, on the other hand, the elements for producing an electrical pulse, for instance, for a fuel supply pump.
  • This invention relates to the new industrial product formed by a support for at least one electric contact breaker device comprising a fixed contact and a moving contact, the moving contact being rigidly secured to a heel adapted to cooperate with an actuating cam, characterized in that the support comprises at least two jaws pivoted tongs-fashion, the jaws being resiliently separable from one another for the introduction between them of the cam for actuating the or each heel and, where applicable, of at least one running bearing surface, the cam and the or each surface possibly being quency is proportional to the speed of rotation of the shaft engaged between the two jaws of the support.
  • This invention therefore relates to the new industrial product formed by the combination of a shaft rotating around its axis with a tongs-like support of the kind hereinbefore defined characterized in that an actuating cam is devised on a portion of the shaft and may or may not be bordered at at least one of its ends by a journal bearing surface, the tongs-like support comprising two devised on a shaft which rotates relatively to the support, the same being maintained stationaryrelatively to. the shaft e.g. by bearing against at least one abutment.
  • the jaws each take the form of two parallel and preferably plastics members with 'a contact breaker device therebetween, each such member being formed in its central region with a recess which in shape resembles half a bearing and which is adapted to cooperate with the cam or with the pivot bearing surfaces rigidly secured to the shaft on which the support is disposed; in cases in which the cam for the or each heel is disposed between two rotating bearing surfaces, the separation between the jaw members is substantially equal to the spacing between the two rotating bearing surfaces; the two jaws are engaged around the last-mentioned surfaces by means of at least one spring which bears on each jaw and which is preferably retained by the pivot pin or spindle or the like associated with the jaws.
  • one of the advantageous uses of A the tongs-like support just defined is to transmit to elements of a motor vehicle pulses or signals whose freresiliently separable jaws which engage between them the zone in which the cam is provided and possibly the or each journal bearing surface, at least one jaw bearing a contact breaker device in the form of a fixed contact and of a moving contact rigidly secured to a heel bearing on the cam, the two contacts of the contact breaker device being electrically connected to the control of an auxiliary element, the tongs-like support being prevented from rotating by bearing against at least one stationary abutment.
  • a combination of this kind is of use e.g. to measure the speed of rotation of a shaft, the frequency of the signals produced by the contact breaker device being proportional to the speed of rotation of the shaft to which the tongs-like support is secured.
  • the support cooperates e.g. with a cam mounted on a transmission shaft between a vehicle gearbox and wheels of the vehicle, and the signals produced by the contact-breaker device actuate speed measuring means.
  • the same step may also be of use for braking control as an anti-skid device; for such uses a support according to the invention is mounted on the axle whose rotation it is required to supervise, the contact breaker device thus mounted producing signals adapted to cancel braking in the event of the axle becoming stationary.
  • the combination according to the invention is a means of producing electricalsignals in excellent conditions irrespective of the movements of the shaft around .which the tongs-like support engages, for since the same is mounted on the shaft .there can be no dispersion of signals due to possible relignition coil.
  • This invention therefore relates to'the new industrial product embodied by an ignition distributor of use more particularly for motor vehicles, the distributor comprising a casing having a'sleeve at the bottom and a distributor shaft running in the sleeve and a distributor cap having contacts for distribution of the highvoltage current, the distributor shaft having a cam with which the heel of at least one contact breaker device in the primary circuit of the ignition coil associated with the distributor cooperates, characterized in that the distributor casing is formed near the cam with an aperture in its side wall, the aperture being closable by a removable cover, and a tongs-like support of the kind hereinbefore described after introduction through such aperture, engages around the cam, the support being prevented from rotating relatively to the casing, preferably by bearing on at least one abutment.
  • each jaw of the support comprises two substantially parallel and e.g. plastics members, the separation between which is slightly less than the height of the cam of the distributor shaft, each such member being formed in its central zone with a recess in shape resembling half a bearing, the edges of each such recess being adapted to bear on the cam protuberances; the two jaws are engaged around a cam by at least one spring which bears on each jaw and which is preferably retained by the jaw pivot spindle, the aperture in the distributor casing side wall extends over an angle of less than 180.
  • the cover closing the aperture in the distributor casing side wall is rigidly secured to the casing by means of a spring in the form of a circular split ring which engages around such casing at the level of the cover.
  • the jaw pivot spindle abuts an abutment rigidly secured to the cover closing the casing aperture, such abutment being disposed near the central zone of the pivot spindle, such abutment taking up a position between the jaw members when the cover closes the aperture in the casing.
  • tongs-like support is to place it in an ignition distributor as a means for producing electrical pulses or signals for an auxiliary element, eg a fuelinjection pump.
  • This invention therefore relates to the new industrial product embodied by an ignition distributor which is of use more particularly for ignition in the cylinders of a motor vehicle engine, the distributor comprising means for producing electrical pulses for an auxiliary member such as a fuel injection pump the distributor comprising a casing and, rotating coaxially thereof, a shaft bearing a cam with which the elements serving for ignition cooperate, characterized in that the distributor shaft also has a cam having at at least one end a journal bearing surface, a tongs-like support which is independent of the distributor casing bearing on the journal bearing surface, the two jaws being resiliently separable for the introduction therebetween of the journal bearing surface, the support bearing at least one contact breaker device having a fixed contact and a moving contact, the moving contact being rigidly secured to a heel adapted to cooperate with the distributor shaft cam; and depending on the direction of distributor shaft rotation the jaw pivot spindle can bear either on an abutment rigidly secured to the distributor casing or on an abutment rigidly secured to a cover associated with an aperture in the distributor
  • a distributor shaft cam is bounded axially by two journal bearing surfaces; the journal bearing surfaces are identical and take the form of sectors of the same cylinder, the sectors being separated by recesses such as can be produced by cutting the cylindrical rubbing surface in planes parallel to the distributor shaft axis; each jaw comprises two parallel and preferably plastics members with a contact breaker device therebetween, the separation between the members being substantially equal to the separation between the two journal bearing surfaces disposed one at each end of the distributor shaft cam; and each jaw member is formed in its central zone with a recess which in shape resembles half a bearing and which is adapted to cooperate with the journal bearing surfaces; the two jaws are engaged around the journal bearing surfaces by at least one spring which bears on each jaw and which is prefer ably secured to the jaw pivot spindle; the aperture in the casing side wall has a height along the casing axis slightly greater than the thickness of the support measured parallel to the pivot spindle thereof, the angle of opening of such aperture being less than the cover adapted to close the casing aperture
  • the jaw pivot spindle is non-movably mounted in a recess in an intermediate member borne by the distributor casing or by an element rigidly secured thereto, the position of the intermediate member relatively to such casing being adjustable;
  • the intermediate member is advantageously formed with a semi-circular slot through which a fixing screw of the casing extends, unscrewing of the screw providing angular adjustment of the intermediate member relatively to the casing by a rotation;
  • the recess in which the jaw spindle is non-movably mounted in shape resembles a substantially radial U which is open in the direction opposite to the direction in which the distributor shaft axis extends.
  • the advantage of a device of this kind is that a tongs-like support which is completely independent of the elements of the actual ignition distributor can be positioned readily, the contact breaker devices on the support serving as a means of producing electrical pulses or signals which are synchronized with engine rotation, since the distributor shaft is engine driven.
  • An ignition distributor of this kind can therefore of course be adjusted completely independently of the adjustment of the contact breaker devices mounted on the tongs-like support.
  • the contact breaker devices for producing the required pulses or signals can be inspected and serviced without any of the ignition elements of the ignition distributor having to be touched.
  • Using a tongs-like support centered on the ignition-distributor shafts cuts out the effect of any clearance between the distributor shaft and the bearing in which it runs at the bottom of the distributor casing.
  • This step of centering on the shaft is known for the contact breaker of the ignition distributor energizing the primary circuit of the ignition coil but has not previously been used in the prior art for producing electrical pulses or signals for an auxiliary element.
  • This main advantage of the invention results more particularly from the fact that the tongs-like support on which the contact breaker devices are positioned is not rigidly secured to the distributor casing but just bears on one or two abutments rigidly secured thereto to prevent the support from turning relatively to the casing.
  • FIG. 1 is a view in elevation of the bottom part of an ignition distributor according to the invention comprising means for controlling an electric injection pump, the tongs-like support being in position and the corresponding cover being absent;
