    Apparatus for controlling the quantity of fuel injected per shot or the beginning of fuel injection in a diesel engine comprises a control rod, which is adjustable by a stepping motor through the intermediary of a resiliently yieldable coupling. The control rod acts to control the injection pump or pumps. In order to provide a structurally simple apparatus which comprises a low-power stepping motor and to eliminate backlash between the cooperating elements of the apparatus, the shaft of the stepping motor carries a camwheel, which is indirectly engaged by the control rod, which is biased by a spring. The resiliently yieldable coupling can be coaxial with the camwheel and adapted to rotate as far as to stop only in one sense of rotation whereas the coupling is rigidly connected to the camwheel for a movement in the other sense of rotation. Alternatively, the coupling can consist of two coupling levers, which are adapted to be pivotally moved apart about a common axis from a position of rest, which is defined by a stop. One of said two coupling levers engages the cam of the camwheel, which is nonrotatably connected to the shaft of the stepping motor. The other of said coupling levers engages an abutment carried by the control rod.

The free end of the arm of the lever 26 is connected to the hub 27, which interacts with the thrust surface 4 of the regulating rail 2, the lever 24 is provided with an axle 28 formed by a trunnion, relative to which the arm of the lever 24 is tensioned by a spring 29 hooked to the levers
    This invention relates to the automatic regulation of internal combustion engines.
    The purpose of the invention is to simplify the construction.
    FIG. 1 is a diagram of the device of FIG. 2 is a section A-A in FIG. 1j in FIG. 3 is a variant of the structural embodiment of the circuit 24 and 26. The locking piston 19 is associated with the device in FIG. 1j in FIG. 4 - with the second shoulder 30 of the lever 24. the same, the cross section.
    The device contains an injection fuel pump 1 (Figs. 1 and 2) with an axially adjustable control rail 2, which is podruschennena prushshnaya 3 in the direction of increasing the fuel supply and through the leash-forming surface of the stop 4 to
    70
    The device works as follows.
    the spacer 5 rests on the control cam 6 of the control disc 7. The control disk 7 is mounted for free rotation on the shaft 8j connected to the shaft 9 of the stepping motor 10. The shaft 8 is fixedly planted with a sectoral plate 11. On the plate 11 the connecting pin 12 is located with an angular spacing in the hole 13, and the axle axis and the hole are parallel . On the control disk 7, an additional pin 14 is installed in the hole 15, with both connecting pins 12 and 14 being connected by a spring 16 of the belt 7keni, and
    When the stepper motor 10 rotates, the control rail 2 moves along a free path, formed due to the gap between the connecting pins 12 and 14 in the holes 13, and 15 with the tension of the spring 16, i.e. first the plate 11 and the stepping engine Yu rotate. , not grabbing the control disk 7, but as soon as the lock
     the control rod 2 is stopped, the spring 16 is compressed, and the control disk 7 is rotated to the position specified by the stepper motor 10, while the control rod 2 is also disconnected, changing the fuel supply. When the fuel pressure decreases, the spring 18 is actuated, which pushes the locking piston 19 to the left (Fig. 1), while the lever 20 turns the diameter of the holes 13 and 15 more counterclockwise, meters connecting pins 12 and 14. To the fuel line 17 spring-loaded spring 18, a stop piston 19 is connected, and the force of the spring 18 exceeds the force of the spring 3; the adjusting distance 5 is removed from the cam 6 of the control 7 of the disk 7, and the regulating rail 2 under the action of the spring 3
    40 chi fuel. By briefly adjusting the control rod 2 when the stepping motor 10 rotates at the first time when the spring 29 is tensioned, move the lever 24 only, and the stepping motor
    Ruyushi rail 2, acting in the direction corresponding to the working position at full load. The spacer 5 is seated on the pivot arm 20, the short second arm 21 of which interacts with the edge 22 of the lock piston 19.
    In the embodiment of the device (Fig. 3, 4), the control rail 2 is spring-loaded with a thick QQ. The second arm 30 of the interaction lever 24 is 3 in the direction of reducing the fuel supply. In addition, the control disk 7 is fixedly mounted on the shaft 8 connected to the shaft 9 by the step of a new engine 10. A control end of the disk 6 of the disk 7 is attached to the free end 23 of the spacer 5 by the lever 24.
    g, which is mounted for free rotation, steps with a stopper piston 19. When the fuel pressure decreases, the spring 18 comes into action and pushes the stopper piston 19 to the right (Fig. 3) 55 so that the lever 26 turns clockwise and the control rail 2, under the action of both springs 3 and 18, is displaced in the direction of decreasing fuel supply.
    25 double arm arm 26. The free end of the arm of the lever 26 is connected to the hub 27, which interacts with the thrust surface 4 of the regulating rail 2, the lever 24 is provided with an axle 28 formed by a trunnion, relative to which the arm of the lever 24 is tensioned by a spring 29 hooked to the levers
    24 and 26. A stop piston 19 is connected to the second arm 30 of the lever 24.
    24 and 26. The locking piston 19 sv with the second shoulder 30 of the lever 24.
    The device works as follows.
    When the stepper motor 10 rotates, the control rail 2 moves along a free path, formed due to the gap between the connecting pins 12 and 14 in the holes 13, and 15 with the tension of the spring 16, i.e. first the plate 11 and the stepping engine Yu rotate. , not grabbing the control disk 7, but as soon as the lock
    the regulating rail 2 is stopped, the spring 16 is compressed, and the control disk 7 is rotated to the position specified by the stepper motor 10, while the regulating rail 2 is also shifted, changing the fuel supply. When the pressure of the fuel decreases, the spring 18 is actuated, which pushes the stopper piston 19 to the left (Fig. 1), while the lever 20 of the turn 5 is turned counterclockwise,
    the spacer 5 is removed from the cam 6 of the control of the disk 7, and the control rail 2 under the action of the spring 3 is displaced in the direction of reducing the flow of fuel. By briefly locking the control rail 2 as the stepper motor 10 rotates, only the lever 24 moves when the spring 29 is tensioned, and the stepper motor 10 can rotate without catching the control rail 2. As soon as the lock stops, the spring 29 is compressed and the corresponding movement of the control rail 2 occurs .QQ The second shoulder 30 of the lever 24 of the interaction
    operates with a stop piston 19. As the fuel pressure decreases, the spring 18 actuates and pushes the stop piston 19 to the right (Fig. 3) 55 so that the lever 26 rotates clockwise, and the control rail 2 under the action of both springs 3 and 18 is displaced in direction of fuel reduction.
