(54) THROTTLE CONTROL DEVICE
Dampers
one
The invention relates to the field of engine building.
Controllers are known for a throttle valve, preferably a carburetor of an internal combustion engine, containing an elastic element installed between the first and second hull elements, for example a diaphragm, which forms with them ventilation and control chambers of variable volumes, the first of which is connected to the atmosphere through the first channel, and the second - through the second and third channels, the valve placed in the third channel, - equipped with a spring and an electromagnetic actuator with a winding, in the supply circuit of which is installed in breakers ignition power resilient member disposed between one of the housing and the elastic element and rigidly associated with an output schtok elastic member configured to contact with the lever mounted on the drive axis of the throttle valve 1.
However, the known devices are structurally complex and, at relatively high engine speeds, cause the fuel to enter the engine in the form of non-evaporated
droplets, resulting in exhaust gases have toxic components.
The purpose of the present invention is to simplify the design of the device and reduce the toxicity of exhaust gases.
The goal is achieved by the fact that the first channel is made in the form of a hole in the first housing element, the second channel is in the form of an aperture with | Lerom in the second corps, and the third -. in the form of an aperture in the second housing element with an outlet window to the atmosphere, and the valve spring is located inside the third channel, and in the second housing element there is a fourth channel connecting the control chamber with the atmosphere and equipped with a safety valve 5.
In addition, the proposed device differs from those known in that an additional winding, for example, an idle economizer valve, is connected parallel to its winding in the power supply circuit of the electromagnetic drive.

FIG. 1 shows the described control device for the throttle valve of the carburetor of an internal combustion engine; in fig. 2 is an electrical circuit of the control device. The control device for the throttle valve 1 of the carburetor 2 internal combustion engine contains a diaphragm 3 installed between the first 4 and second 5 body elements forming a ventilating 6 with it and controlling 7 chambers of variable volumes 7, the first of which is connected to the atmosphere through the first channel 8, made in the form of a hole in the first body element 4. The control chamber 7 is connected to the atmosphere through the second 9, third 10 and fourth 11 channels made in the form of holes in the second body element 5. The second channel 9 is named It has a nozzle 12 and an air filter 13, the third channel 10 has an outlet window 14 to the atmosphere, and the fourth channel 11 is equipped with a safety valve 15 loaded with a spring 16 and an air filter 17. The third channel 10 has a valve 18 and its spring 19. The valve 18 is rigid associated with the core 20 of the electromagnetic drive having a winding 21. The second body element 5 is made with a fastening element 22, with which the control device is installed near the carburetor 2. Elastic force element is mounted between the diaphragm 3 and the second body element 5 t formed by a helical spring 23 placed in the control chamber 7. A diaphragm 3 is rigidly connected to an output brush 24, which is made in contact with a lever 25 mounted on the drive axle 26 of the throttle valve 1 and connected to the thrust 27 and spring 28 The force of which is directed towards closing the throttle valve 1. As can be seen from FIG. 2, the electromagnetic drive winding 21 has a power supply circuit 29 in which the ignition switch 30 is installed and parallel to the winding 21 — an additional winding 31 with a bark 32 rigidly connected to the idle economizer valve 33 of the carburetor 2. The operation of the device is as follows. During normal operation of the internal combustion engine, the ignition switch 30 is closed, as a result of which current is flowing through the windings 21 and 31. Therefore, the valve 18 is mounted by the crown 20 to the position of blocking the third channel 10 (as shown by the dotted line), and the valve 33 is set to the open position of the idle system. When the engine is idling, the throttle valve 1 is set to a position close to closing and the output rod 24 is in contact with the lever 25 under the influence of the helical spring 23 (as shown in Fig. 1). When the throttle valve 1 opens, the lever 25 rotates, moving away from the control device, causing the diaphragm 3 under the action of the helical spring 23 to move, increasing the volume of the control chamber 7 and reducing the volume of the ventilation chamber 6. From the latter, the air freely leaves through the first channel 8 and air is supplied to the control chamber 7 (relatively free) through the open safety valve 15. When the throttle valve 1 of the engine moves from the open position to the closed position, the lever 25 moves the outflow one rod 24 inwards, overcoming the force of the coil spring 23. As a result, the volume of the control chamber 7 is reduced and air comes out only through the nozzle 12 of the second channel 9, since the safety valve 15 is closed at this time. Therefore, the air from the control chamber 7 is released slowly, damping the movement of the throttle valve to the closed position and reducing the toxicity of exhaust gases. When the internal combustion engine stops, the force is removed from the rod 27 and the contacts of the ignition switch 30 are opened. As a result, the windings 21 and 31 are de-energized, and the valve 18 is transferred by the spring 19 to the open position of the third channel 10, and the valve 33 to the closed position of the idle system. In this connection, the throttle valve 1 is transferred by the spring 28 to the closing position almost instantaneously, since the air can escape from the control chamber 7 not only through the nozzle 12, but also through the output window 14 of the third channel 10, and shut off by the valve 33 of the idling system prevents fuel from entering the engine's cylinders, thereby preventing its operation from glow ignition and ensuring its quick stop. Thus, the proposed control device, with its simple construction, provides a slow cover for the throttle valve during engine operation and quick shutdown when stopped, resulting in reduced exhaust gas toxicity. Claim 1. Control device for a throttle valve, preferably a carburetor of an internal combustion engine, comprising an elastic element installed between the first and second body elements, for example, a diaphragm forming a variable volume ventilating and controlling chambers, the first of which is connected to the atmosphere through the first the channel, and the second through the second and third channels, the valve placed in the third channel, equipped with a spring and an electromagnetic actuator with a winding.
