Description

The invention relates to the automatic regulation of internal combustion engines. Known are devices for regulating the rotational speed of a diesel engine shaft with a mechanical regulator, a fuel pump connected to an engine camshaft and a gear installed in the crankcase, which contains a regulator lever that is hinged to gear case, and equipped with a fork-shaped end part opposite to the hinge and connected to the toothed pin, the stem of the shaft connected to the lever Torr st speed control lever coupled to the transmission casing by means of an additional hinge ipruzhinu regulator associated with ry. control knob and speed control lever 1. In known devices, the regulator lever is held in contact with the rotational frequency control lever, which is manually actuated using a spring. The regulation of rotational speeds is carried out by moving both levers. However, such use creates difficulties and inconveniences in regulating the rotational speed due to the limitation of the range of movement of the pLP control loop. In addition to working at idle, the force of the mechanical regulator is insufficient to control the spring of the regulator. The purpose of the invention is to simplify the design. To achieve this goal, the device is equipped with a spring of idling connected to the fork end of the regulator lever and the transmission crankcase, with an engine stop lever connected to the frequency control knob of the additional hinge, and a finger to receive the lock lever connected to the lever regulator. FIG. 1 is a diagram of the installation of the device on the engine, - FIG. 2 is a horizontal section A-A in FIG. 1) in FIG. 3 is a vertical section BB in FIG. 2, in FIG. 4-6, the kinematic diagrams of the device in various operating positions, in FIG. 7 and 8 versions of the mechanism for adjusting the tension of the idle spring. The diesel engine contains a cylinder 1 (FIG. 2), a piston 2, your knee 3, a crankcase 4 and a gear 5 for transmitting the rotation between the crankshaft and the cam shaft 6 of valve gear. To the front wall of the crankcase 4 of the engine is attached crankcase 7 gear 5. At the end of the crankshaft 3 is installed with the possibility of free swing on the bracket 8 a pair of weights 9 mechanical regulator. A sliding rod 10 is inserted into the crankshaft. The mechanical regulator consists of a bracket 8, weights 9 and a sliding rod 10 and. denoted by the general position 11. In the gear housing 7, the hinge 12 is installed with the possibility of free rotation with the regulator arm 13 installed on it in contact with the sliding rod 10. In addition, the additional hinge 14 is installed in the gear casing for free rotation with the lever 15 mounted on it (fig. 3) of the rotational speed control, manually controlled outside the crankcase-4. Between the locking lever 16 fixed on the hinge 12 and the lever 17 fixed on the additional hinge 14, is installed spring 18 regulator. Under the influence of this spring growling :; The regulator 13 is held in the increased fuel delivery position. The tension of the spring 18 can be adjusted by adjusting the rotational speed 15. Inside the gear housing 7, the fuel pump 19 is installed, the toothed pin 20 of the fuel control valve of which is located on the crown in the coupling with a fork-shaped end part 21 of the lever-13 regulator. Thus, the amount of fuel supplied by the pump can be adjusted by setting the rail pin 20 to the desired position with the regulator lever 13. The regulator spring is fixed on both sides in the levers 16 and 17, and its ends enter into the openings 22 and 23, respectively. The idling 24 is installed between the fork-shaped part 21 and the adjustable screw 25 mounted into the wall of the 7.zubchatuyu transmission. The engine stop lever 26 is attached to an additional hinge 14. The movement of the engine stop lever 26 is limited by a finger 27, which is provided with a lever 13 of the regulator. A mechanical regulator 11, is placed inside the gear housing 7. a control lever 13, a regulator spring 18, levers 16 and 1, an engine stop lever 26, a finger 27, an idle spring 24, and a pump body 18. : - The adjusting nuts 28 (Fig. 7) are designed to adjust the tension of the spring 24 of idling with the protective cap 29 removed and with the spring fixed 24. In another embodiment, the adjustment of the spring 24 can be accomplished by the cap nut 30 and the lock nut 31 when fixed spring 24 through the bushing 32. The device operates as follows. . When the engine is idling, the control lever 15 is set to the Idle position (FIG. 5), and the regulator lever 13 is prevented from acting on the back of the spring 18, but is limited from moving to the reduced fuel supply position. The force from the weights 9 is transmitted through the lever 13 to the rail of the fuel pump 19. Possible and undesirable fluctuations of the rotational speed are eliminated by the idling spring 24 and the balancing force of the weights 9 of the mechanical regulator 11 at idling speed. When switching to any engine operating mode, the speed control lever 15 is moved to the Engine running position (Fig. 4. The finger 27 provides the control lever 13 with the ability to move and transfer the force of weights 9 to change the setting of the fuel pump rail. 19 D ; 2rffJ / 7 / k7 / ff. Fig. G in the direction of the magnitude of the fuel supply. The spring 18 is tensioned, with the result that the lever 16 moves in the direction of the lever 17. The tension of the tension of the spring 18 is matched with the force transmitted by the rod 10, which provides automatic adjustment rotational speed to a predetermined value. When the engine is stopped, the lever 15 is moved to the stop position, the engine (Fig. 6), as a result of which the tension of the spring 18 weakens to zero and the levers 16 and 17. are released from its influence. The lever 26 pushes the pin 27, forced the lever-13 and together with it the rail of the fuel pump 19. move against the action of the spring 24 in the direction of stopping the supply of fuel. At sTOivi the engine stops. The use of the device will make it possible to simplify the regulation of the frequency of rotation by the lever for regulating the frequency of rotation by simultaneously releasing the lever of the regulator from the action of the spring of the regulator. In addition, fluctuations in the speed of rotation will be eliminated by the regulator spring. The dimensions of the device allow it to be placed in the gear housing. f
