On engines the distributor of ignition 47.3706 manufactured on the basis of the distributor of ignition 147 A, differing from it in characteristics of centrifugal and vacuum regulators is installed.

The case of the distributor is cast from aluminum alloy. In the case 6 the shaft 19 which rotates in two bearings 18 of sliding pressed in a case shaft is located. Lubricant of bearings is carried out by a drop butterdish 4.

On a plate of a shaft 19 the mechanism of the centrifugal regulator is located, at disclosure of small weights 17 which under the influence of centrifugal forces there is a turning on some corner of a tetrahedral cam 8, than earlier or late disconnection of contacts of the breaker is provided, and, therefore, the spark proskakivaniye moment between electrodes of spark plugs respectively changes.

The breaker of current of low voltage is fixed on the mobile plate 24 connected by draft 22 to a diaphragm of the 29th vacuum regulator and also the rychazhka 28 with contact and the textolite pillow pressed by a spring to a tetrahedral cam consists of a rack with motionless contact 25.

The surface of a cam is greased with the fillets impregnated in oil 20. Between mobile and motionless plates of the breaker the ball-bearing is installed. Parallel to contacts of the breaker the condenser 5 strengthened on the distributor case by two screws is switched on.

Distribution of a high-tension current on spark plugs on the engine is carried out by the runner 10 rotating together with shaft located under a plastic cover 9.

In the central electrode of a cover of the distributor the contact piece of coal 13 is built in combined (with a resistance). The mass of small weights and effort of a tension of springs of the centrifugal regulator are picked up so that to provide change of the moment of ignition depending on the frequency of rotation of a bent shaft of the engine.

The vacuum regulator 23 advancings of ignition changes the ignition moment depending on engine loading (on depression in an inlet pipe).
