    The timing device comprises compression springs (7,8) each biassed between a pair of guiding pieces (3,4). One guiding piece (3,4) of each pair is fixed to a primary rotary member (1), and the other guiding piece (5,6) of each pair is fixed to a secondary rotary member (2). As rotary speed increases, fly-weight (9) guided between the guiding pieces (4,5 or 3,6) move outwardly against the bias of the springs so as to alter the relative rotary position of the primary and secondary members (1,2). In order to reduce wear and friction each fly- weight (9) has two members (11,12) freely rotatable relative to each other. One rotatable member (11) is in rolling contact with one guiding piece (3) and the other rotatable member (12) is in rolling contact with the other guiding piece (6). <IMAGE>

    This invention relates to a motor structure, in particular to the automatic regulation of internal combustion engines. Devices are known for adjusting the injection advance angle as a function of the speed of turning two coaxially located shafts of internal combustion engines, such as a diesel engine, containing a driving gear rigidly connected to the crankshaft, a driven gear rigidly connected to the drive shaft of the fuel pump, and return springs connected on the one hand with two guiding elements of the driving gear, and on the other with two guiding elements of the driven gear, with the guiding elements of both gears connected to each other with centrifugal weights. In known devices, the drive and driven gears can be adjusted one relative to the other in such a way that with increasing rotational speed, fuel is injected all later. Their mutual movement takes place with the help of centrifugal weights, which are slid along the direction of the central elements, moving THEY relative to each other. Such control devices are quite compact and structurally simple. However, the influence of friction, as well as the presence of macro- and microstructures. The direction of the right elements leads to a strong variation of the adjustment characteristic. Moreover, during long-term operation, wear of the guide elements and centrifugal weights occurs, which affects the control accuracy. To some extent, the negative influence of the surface structure of the guide elements can be eliminated with the help of precision surface treatment, but it is technologically impossible to achieve narrow limits on the change in the coefficient of friction. The purpose of the invention is to reduce friction between guide elements and centrifugal weights. This goal is achieved by the fact that centrifugal weights are made up of two disks freely rotating relative to each other, the first of which is connected to one of the axes of the leading elements of the pinion gear, and the second with one of the axes of the driven gear elements. Zana with their gears. The centrifugal weights are made in the form of at least two primary discs and a central pin, at least one of the primary discs mounted on the central pin for free rotation. The centrifugal weights are equipped with a distal ring located on the central finger and three disks, the two extreme ones rigidly fixed to the central finger and located on it on both sides of the remote ring on which the Medium disk is installed with the possibility of free rotation. The middle disk is mounted on the distance ring using a sliding bearing.
    The middle disk can be installed on the distance ring with the help of a roller bearing.
    Freely rotating rotary disks of centrifugal weights are made with the same diameters,
    Return springs are provided with adjusting nut L and at the ends.
    Figure 1 presents the scheme of the device with a partial cut; on ig.2 - section aa in figure 1; on the FIG. 3 — embodiments of centrifugal weights according to the variant illustrated in FIG. 1, FIG. 4 shows another embodiment of the weights.
    The device contains a driving neck - 15 tern 1 (fig., Rigidly connected with a crankshaft (not shown), a driven gear 2, xtecTKo connected to the drive shaft of the fuel pump, and return springs 3 and 4 are connected -20 respectively with one side with two guiding elements 5 and 6 leading 1: its gear 1, and on the other side with two directions 7 and B of the driven gear 2, and the guide elements 5–8 of both gears are interconnected with each other centrifugal weights 9. All guiding elements are made in the form of –segment levers Nost sliding m "which are pressed by means of springs 3 x reciprocating and centrifugal 4 gruziui 9. Figure 2 shows the upper centrifugal sinker in the initial position, the bottom - in the middle position.
    The centrifugal weights 9 are made up of two disks 10 and 11 freely rotating relative to each other, one of which is connected to one of the directions of two elements 5 or 6 of pinion gear 2 and the other 40 with one of guide elements 7 or 8 of driven gear 2, the guiding elements being rigidly connected with their gears.
    The centrifugal weights could be 45 made of at least two disks 10 and 11 and a central pin 12 (Fig. 3), with at least one of the disks, for example a disk 11, mounted on a central finger with 50 possible free rotation.
    Additionally, centrifugal weights can be equipped with a distance ring 13 located on the central pin 12, equipped with three se disks 1 O, 11 and 14, two extreme heads 10 and 14 are rigidly fixed on it and located on both sides of the remote ring 13 on which middle disk 11 with the possibility of free rotation (fig. 3). The middle disk 11 can be mounted on the distance ring-e 13 with thickening of the roller bearing 15 or the sliding bearing.
    The disks 10 and 11 can be made with the same diameter (figure 2 or with different Sfig.Z).,
    The return springs 3 and 4 are equipped with adjusting nuts at the ends. :
    The centrifugal weights 9 can be made in the form of two disks L17 and located on a common finger 18 with the possibility of free rotation. The dike 16 is connected with the direction of the 5th element 5, and the disk 17 is connected with the direction of the element 7. Both disks are fixed on the finger 18 when the roller rolls under the hips 19 (Fig. 4).
    The device works as follows.
    At steady state speed of the crankshaft of the engine, the device acts as a coupling with the drive shaft of the fuel pump, to which rotation is transmitted from the crankshaft. ;
    When the speed changes, the centrifugal weights 9 disperse, overcoming the force of the springs 3 and 4, squeeze the guide elements 5-8 from each other and move the driven gear 2 relative to the drive six wheels 1. With the change in speed of the eras-: drive shaft of the fuel pump change the advance angle of fuel injection. When the device is in operation, discs 10, 11, and 14 are rolled around the adjacent surfaces of guide elements 5-8. In addition, central disks 10 and 14 are rolled around. 12 and the middle disk 1 1 of the distance ring 13 using an adhesive pad 15, which eliminates sliding friction. In this case, the guide element 5 is actuated by the wheels 10 and 14 1 (Fig. 3), and the guide element 7 is middle disk 11. When two disks 1b and 17 are used (figure 4, they will be run around with respect to the guiding elements 5 and 7 and the finger 18 with the help of podashpkki 19.
    The use of the proposed device reduces the friction between centrifugal weights and the contacting surfaces of the guide elements, which will stabilize its adjustment characteristics and improve the accuracy of adjustment.
