    A fuel pumping apparatus for supplying fuel to a supercharged compression ignition engine includes an injection pump having a control member the setting of which is determined by a governor including speed responsive means and a governor spring the force exerted by which is adjustable and opposes the action of the speed responsive means. A stop member is provided to limit the extent of movement of the control rod and the stop is engageable with a cam surface formed on a pivotal lever the setting of which is controlled by an air pressure responsive member subjected to the air pressure existing in the inlet manifold of the engine. In addition the pivot for the lever is mounted on a carrier member which is loaded by a spring. The spring can be deflected under certain operating conditions of the engine, by the force exerted by the governor spring and this provides a measure of torque control.

    FIELD OF THE INVENTION. Devices for supplying fuel to a supercharged diesel engine are known, comprising a fuel injection pump having a rail control, a movable stop rail and a correction device including a housing with a lever mounted on it, one end of which has a cam in contact with the stop and the other is connected via an axis with a spring-loaded diaphragm rod located in the cylinder, the diaphragm of which is communicated with the charge-line Dl. The disadvantage of these devices is the complexity of their implementation. The purpose of the invention is to simplify the design. To achieve this goal, the cam of the lever is connected to the movable spring-loaded element, and the axis of the lever arm is extended to interact with the adjustable rod stop. The movable element is made in the form of a fork mounted on a rod placed in a stop sleeve having a threaded connection with the housing for adjusting the stroke of the movable stop. In addition, a stop is attached to the rod by means of a thread in the direction of reducing the supply of top brew. Chetok's stroke limiter is made in the form of a plate with a protrusion fixed to the body, or in the form of a protrusion, having a screw connection with a body bolt and a stopper. FIG. 1 shows a device, a schematic diagram; in fig. 2 corrective tool, longitudinal section; in fig; 3 - the same cross section; on . 4 - rod stop in the form of a plate with a protrusion; in fig. 5 - the same, in the form of a protrusion having a screw connection with the housing bolt. The device contains a fuel-injection pump 1 having a control in the form of a rail 2, a movable stop 3 of the rail and a correction technique that includes a housing 4 with a lever 5 mounted on it with hinges. One end of the lever 5 has a cam 6 in contact with the stop 3, and the other is connected with help
    axis 7 with a spring-loaded stem 8 of the diaphragm 9 placed in the cylinder 10, the subdiaphragmatic cavity 11 of which communicates with the main above the duvovo air. The cam b of the lever 5 is connected to the movable spring-loaded element 12, and the axis 7 of the attachment of the hub 5 is made elongated to interact with the adjustable stroke limiter of the rod 8, which is made in the form of a plate 13 with the inlet 14, fixed to the housing 4 by means of a bolt 15, or in the form of a protrusion 16 having a screw connection with the bolt 17 of the housing 4. The movable element 12 is made in the form of a plug 18 fixed on a rod 19 placed in the sleeve support 20 having a threaded connection with the housing 4 for adjusting the stroke of the movable stop 3. On rod 19 per fastened by thread 21, the stop 22 in the direction of reducing the fuel supply. The housing 4 is provided with a hollow bolt 23 with a filter 24 for providing air movement during operation of the diaphragm 9. The filter 24 is closed by the cap 25. The rail 2 has a connection through the spring 26 with the handle of the operator 27 and with the movable part of the centrifugal regulator 28.
    The device works as follows.
    When set by the operator's handle
    27 engine operation, in which the rail 2 comes into contact with the movable stop 3, the equilibrium state of the moving parts of the device is determined by the equality between the force / I and the action of the centrifugal regulator
    28 and the spring member 12,
    and from the action of the spring 26. The equilibrium state of the movable parts of the device (rail) is disturbed (at the given position of the handle 27) in the event of a change in the engine speed (for example, when the engine load changes) or in the case of a rotation of the cam 6 of the lever 5 when the diaphragm 9 moves with the rod 8 under the action of a change in the pressure of the charged air. When the equilibrium state is disturbed, the rail 2 moves, causing a change in the amount of fuel supplied when the handle 27 is changed. After the forces are equalized from the centrifugal regulator 28 and the sprung element 12 and from the spring 26, the rod 2 takes a new position, corresponding to new engine operating condition. As a result of the adjustment, the fuel is supplied both as a function of the change in the engine speed and as a function of the pressure of the blower air. Moreover, the magnitude of the adjustment of the fuel supply depending on the pressure of the charge air is determined by the cam 6 profile, and depending on the engine speed, the characteristic of the centrifugal regulator 28. With increasing pressure of the charge air, the movable stop 3 has a greater displacement, which corresponds to an increase in fuel supply . The increase in fuel supply also occurs with a decrease in the engine speed.
    Thus, with a simple constructive implementation, the device allows the adjustment of the fuel supply when the number of revolutions and the pressure of the charge air is changed.
