    (54) CARBURETTIC AIR VALVE KNOT FOR INTERNAL COMBUSTION ENGINE
    The invention relates to an engine structure, in particular to a carburetor choke assembly. The carburetor choke assemblies for an internal combustion engine are known, comprising a plate placed in the flow channel of the housing, mounted on a roller, an driving disk rigidly connected to the roller, eccentrically located in the flow channel, a driving element freely mounted on the roller and made from a contact surface and connected to a disk by means of a spring, a control rod connected with a driving element, and a vacuum drive connected to the throttle space of the flow channel and provided with a connector This is CiJ. However, in the known air damper assemblies, the plate does not move alternately to open the inlet duct with a vacuum drive, depending on the ambient temperature. The purpose of the invention is to improve the accuracy of the plate installation in the engine starting conditions at low temperatures. The goal is achieved by the fact that the drive disk is provided with a protrusion and an intermediate disk freely connected to the connecting rod of the vacuum drive and having a stop for the protrusion and a supporting element is freely mounted on the roller, and a rotary limiter is mounted on the housing, which has a tracking element resting on the contact surface of the drive member, and adapted to communicate with the supporting member of the intermediate disk when the control rod is moved. Moreover, the contact surface of the driving element is made in the form of a cam, and the follower element of the rotary limiter, in the form of a pusher in contact with the cam. Figure 1 shows the proposed carburetor choke assembly for an internal combustion engine; . 2 and 3 are the same, with some parts removed; 4 is the same at the first position of the control rod; Figure 5 - the same, with the second position of the control rod. Carburet air damper assembly. For the internal engine, the engine contains a plate 3 mounted on a roller 4, eccentrically located in the flow channel 1, a drive disk 5 rigidly connected to the roller 4, a driving element 6 freely mounted on the roller 4, connected with disc 5 by means of a coil spring 7, the force of which is directed towards the joint-protrusion 8 of the disc 5 with the thrust surface 9 of the driving element, pull 10 controls, equipped with a manual control button 11 and connected with a cable 12 and a hinge 13 the driving element b, and the vacuum drive, the working chamber 14 of which, forming on the body element 15 and; the membrane 16, is connected via pipe 17 to the throttle space of the flow channel 1, and the membrane 16 is equipped with a spring 18 and is connected to the connecting rod 19. The intermediate disk 20 is loosely mounted on the roller 4, connected by means of a hinge 21 with a connecting rod 19. The intermediate disk 20 has an abutment 22 that can come into contact with the protrusion 8 of the drive disk 5, and the supporting element 23. On the body 2 installed spring loaded gating limiter 24 configured to rotatably; around axis 25 and fitted with a follower element 26, which is supported on the contact surface 27- (Figures 2 and 3} provided on the driving element 6 ". The contact surface 27 is in the form of a cam and the follower element 26 is in the form of a pusher. The control steering 10 is located in the hub 28f of the vehicle body fixed in the wall 29 and having a ball retainer 30. The carburetor air damper assembly operates as follows: Before starting the heated engine, the plate 3 is set to full open position The first channel 1. At this, the button 11 is pressed against the sleeve 28, and the protrusion 8 of the drive disk 5 and the abutment surface 9 of the driving element 6 are in contact with each other (Fig. 1). The element of the vacuum drive is in the position (figl). when the latter takes steady speeds, the dilution due to the throttling space through the pipeline 17 is transmitted to the working chamber 14 of the vacuum drive, in connection with which the membrane 16 overcomes the force of the spring 18 and moves to the core element 15, at the same time connecting the t gu turns prom daily disk 20. However, the latter does not change the position of the plate 3, since the stop 22 does not reach the protrusion 8. The support element 23 also does not come into contact with the rotary stop 24. Thus, when the warmed-up engine starts, the air damper assembly does not affects the composition of the mixture prepared by the carburetor. Before starting the cold engine at low ambient temperature, the button 11 tons of the ha-control 10 moves in the sleeve 28 for as long as; the latch 20 will not enter the recess 31 provided for by the control unit 10 (Fig. 4). As a consequence, the cable 12 tends to turn the driving element 6 relative to the roller 4, however, the spring 7 displaces the drive disk 5 together with the driving element 6, and thus the roller 4 turns, which sets the plate 3 to a position completely blocking the flow area of the flow channel 1. The next element 26 remains in contact with the annular region of the contact surface 27, as a result of which the rotary stop 24 remains stationary relative to the housing 2. During engine start up until the latter starts to work at steady speed, plate 3 overlaps the flow area of flow channel 1. As soon as the engine runs at steady speed, the air flow going through flow channel 1 tends to turn plate 3 to the open position . At the same time, a vacuum is transferred into the working chamber 14 of the vacuum drive from the throttle space, in connection with which the membrane 16 moves the connecting rod 19 and together with it turns the intermediate disk 20 counterclockwise. The latter, with its abutment 22, acts on the protrusion 8 of the drive disc 5, which also turns the roller 4 into the open position by the plate 3 of the flow area of the flow channel 1. At the same time, the supporting element 23 does not reach the rotary stop 24, and therefore the plate 3 moves to the full open position sections of the flow channel 1 under the action of a vacuum drive and air flow. When starting a cold engine in conditions of very low ambient temperature, the button 11 is pushed further out of the sleeve 28 so that the notch 31 passes the locking device 30 (Fig. 5). The cable 12 turns the driver 6 so that after moving the plate 3 together with roller 4 to the position of complete blocking of the flow area of the flow channel 1, the abutment surface 9 moves away from the protrusion 8, and the spring 7 receives a greater tightening force. The next element 26 is moving. on the contact surface 27, is shifted to the maximum
    moving away from the roller 4 and turning the stop 24 so that it can come into contact with the supporting element of the intermediate disk 20. After the engine is started, that is, it starts to work at steady speed, the vacuum in the working chamber 14 of the vacuum drive shifts the diaphragm 16 and the connected tag 19 displaces the intermediate disk 20, which by the stop 22 moves the drive disk 5, the roller 4 and the plate 3 to the position of the slightly open flow area of the flow channel 1. However, the rotation of the plate 3 occurs until the supporting element 23 enters into contact with the rotary stop 24. In this case, the plate 3 does not fully open the flow area of the flow channel 1, i.e. is in an intermediate position. This provides a change in the composition of the mixture prepared by the carburetor for starting and warming up a cold engine in conditions of very low ambient temperatures.
    After the engine warms up, a button 11 t gu-10 is pushed into the sleeve 28, and the plate 3 moves to the full open position of the flow area of the flow channel (Fig. 1).
    Thus, with such a configuration of the carburetor choke assembly, the position of the plate after starting the engine depends on the amount of extension of the control 10 from the sleeve 28 and, consequently, the accuracy of mounting the plate under conditions of low ambient temperatures improves.
