  The present invention relates to a dispensing machine.

  motor vehicles of the type having a rotor which was: i-

  accurate tem- perature with respect to the cylinder

  The positicornment of the rotor is most often performed in

  the rotor support and drive shaft which is accurate. at-

  mechanical means to the camshaft of the meter, and to rotate the assembly formed by the housing and the dispenser head to obtain the concordance of the electrode disposed sua 'lt rct'r with -'

  output terminals mounted in the distributor head.

  The object of the present invention is to suppress this process.

  indexation and consceque, n the implementation of the means necessary this operaion and concerns for this purpose a dispenser alltuia-e for self-contained vehicles of the type comprising on the one hand end a) arbsre, driven in rotation by an element of the motor, secured to the shaft, a rotor on which is fixed an electrode and other pa nr sealing cap which caps the housing of the distributor and comprises means which in combination with the housing promotes the centering

  door on the one hand a seat of the rotor kept suspended and connected

  to the sealing hood by self-sealing means from the

  rotation of the shaft and comprising a part of means of inr-

  dexation of the rotor, with respect to one of the pre-engine cylinders of the engine -t secondly a wear washer disposed between the trap and mn

  It is important to understand how the invention can be realized.

  FIG. 1 is a sectional view of a corresponding ignition distributor

to the invention.

  FIG. 2 is a perspective view of a dispenser variant

  FIG. 3 shows an ignition distributor after rotation

of the support shaft of its rotor.

  FIG. 4 is an enlarged representation of part A of the

figure 3.

  According to FIG. 1, the distributor of electricity which is provided with the invention

  The idea of opening a seat 8 of the rotor 2 is ra interns-

  hanged concemingly. cent-re: - hood (of secareté 5, by means

  which are formed by a plurality of bridges 9,

  ta-nt a median part 9c with reduced section, which connect the seat 8

at the hood 5.

  In addition, this seat 8 has a plurality of grooves 11 whose number may advantageously correspond to the number of cylinders equipping

the engine of the motor vehicle.

  Completely rotor 2 has at least one side 10 which

marries the shape of the grooves 11.

  The position of the grooves 11 is defined arbitrarily relative to

  by means of the centering 6 of the head 7 of the dispenser.

  This combination of the grooves II and the rib 10 favors the in-

  dexation of the electrode 3 with respect to the output terminal 15 and subsequent

  quenment with respect to the chosen cylinder.

  With such an assembly as soon as the rotor 2 is rotated, the bridges

  9 are broken at the middle part 9c, the seat 8 then tends to

  The bearing 13 being metallic, an anti-wear washer 12 is disposed between the

  seat 8 and landing 13 in order to minimize the risk of

  metal dust by friction between the seat 8 and the

landing 13.

  According to FIG. 2 this washer 12 is made of plastic material

  tick and is placed on the landing 13.

  In alternative embodiments the roundelile 12 may be either constituted by a lamb "Truarc" housed in a groove made at the periphery of the shaft 1, or obtained from material with the seat 8 such that

shown in Figure 1.

  In this latter embodiment the hood 5 made of plastic material therefore comprises the positioning means 6 of the head 7 of the distributor, the bridges 9 which concentrically maintain the seat 8 which comprises means 14 for snapping the assembly into

  throat 15 made on the periphery of the artre 1.
