    The invention relates to automatic regulation and can be used in gas supply systems for internal combustion engines. A known regulator for the supply of gaseous fuels to an internal combustion engine, comprising a housing, between the inlet and outlet cavities of which is installed a regulating body associated with a membrane, which forms a command and working cavity with the housing, however, this regulator has a layered design, The closest in technical essence to the present invention is a regulator for supplying gaseous fuel to an internal combustion engine, comprising a housing with a membrane sensing element associated with the regulator, tanovlenii between the inlet and outlet channels 2j. The disadvantage of this regulator is the low speed (the inability to quickly change the amount of combustible mixture in accordance with any changes in engine load), the purpose of the invention is to increase the speed of the regulator, the goal is that those in the gas pressure regulator for the engine internal combustion containing housing. between the inlet and outlet cavities of which the first regulator is installed, which is connected with the first membrane forming the first command and working cavities to the case, the second membrane forming the second command cavity and the second regulator, made in the form of the first nozzle located opposite the second membrane in the form of a truncated cone, the smaller base of which is connected to the working cavity by the first channel connected through the second perpendicular to the axis of the truncated cone al, an output cavity-regulator and through a second nozzle mounted coaxially with the second channel, with intermediate cavity connected via the starting valve connected to the control device, with the inlet cavity, parallel to the second membrane end frustoconical flange installed. The first regulator is installed in an additional cavity, which is coaxial with the output cavity, and through the choke with the intermediate cavity. The valve of the first regulator is designed as a washer installed above the saddle with an annular groove, in which the forked end of the lever is installed, kinematically connected with the first membrane the washer is connected to the spring. The spring is mounted on a hinge element. The second command cavity is connected to the suction piping of the internal combustion engine. The control unit of the starting valve is made in the form of a solenoid connected to the output of the delay circuit, the input of which is connected through inductive or capacitive coupling to the high-voltage conductor of the ignition distributor. Fig. 1 shows a regulator circuit; in FIG. 2, a throttling organ; Fig. 3 is an electrical diagram of the ignition system. The regulator comprises a housing 1, between the inlet 2 and the outlet 3 cavities of which the first regulator 4 is installed, which is connected to the first membrane 5, which forms the first command 6 and the working 7 cavity in the outlet 1, which form the second membrane 8 in the output cavity the command cavity 9, and the second regulator, made in the form of a first nozzle 10 opposite the second membrane 8, in the form of a truncated cone, the smaller base of which is connected to the working cavity 7 by the first channel 11 connected through the second perpendicular A channel 12 locally located to the axis of the truncated cone, with the output cavity of the regulator 3 and through the second nozzle 13 installed coaxially with the second channel 12, with the intermediate cavity 14 connected through the starting valve 15 connected to the control device 16, made for example in the form of an electromagnet, with an input cavity 2, parallel to the second membrane 8, a flange 17 can be installed at the end of the first nozzle 10, the first regulator 4 can be installed in an additional cavity 18 connected to the output cavity 3 and through the choke 19 - intermediate cavity 14, Case 1 is provided with covers 20 and 21, which hold the first 5 and second 8 membranes, respectively. The first command cavity 6 is connected through the opening 22 in the lid 20 with the environment. The second command cavity 9 is connected to the suction pipe of the internal combustion engine through the pipe 23 in the cover 21, so that in the second command cavity 9 a pressure is created that is different from the pressure in the outlet cavity 3. In the presented example, the nozzle 23 can be connected to the latter by means of an air filter introduced into the suction pipe. The outlet cavity 3 through the pipe 24, the cross section of which is significantly larger than the maximum amount of the mixture flowing out of the outlet cavity 3, is connected to the suction or supply pipe of the internal combustion engine to create in the outlet cavity 3 a pressure corresponding to the effective pressure, which reduces stress losses and pressure drops. Through the third channel 25, the output cavity 3 is connected with an additional cavity 18 formed in the housing 1. The first regulating member 4 has a third nozzle 26, which from its side is connected to the fuel source through the entrance cavity 2 and the connecting nozzle 27. The opening of the opening of the third nozzle 26 is controlled by the locking member 28, which with the help of the hinge 29 of the fastened lever 30, fixed by a pin 31 in the walls of the additional cavity 18. The lever 30 is actuated by a spring 32 controlling the position of the locking member 28 the edge of the opening of the third nozzle 26. The end 33 of the lever 30 operates in conjunction with the rod 34, which slides along the guide inside the wall of the additional cavity 18 and is connected via plate 35 with the first membrane 5. Thus, the movement of the membrane 5 causes nye change in pressure in the working chamber 7 through the lever 30 are transmitted over PORN body 28 for controlling the supply of fuel into the suction boprovod labor. The entrance cavity 2 is connected via the fourth cane 36 to the chamber 37, where the starting fan 15 slides, forming a locking member, which is pressed by means of the spring 38 to the saddle. The chamber 37 by means of the starting valve 15 is connected to the intermediate cavity 4. The choke 19, the seat 39 of which is connected by the fifth channel 40 to the additional one. cavity 18, serves to limit the supply of fuel, especially during start-up or excessive engine overloads. A rod 41 is fixed on the starting channel 15, which can control the supply of the combustible mixture. Starting fan 15 is used in features immediately before launching the engine. The drive of the starting valve 15 can be controlled by using a static pressure that follows pressure changes in the suction of the engine piping, or by using a tachometric element responsive to the engine speed, or by using an electric element connected with the ignition of the engine , which makes it easier to start the engine, especially under load. In this case, first open the start valve 15, which normally remains closed by means of a spring 38, and the fuel from internal cavity 14 through the second nozzle 13 and seat 39 into the suction conduit i engine, whereby the engine is started. Immediately after starting, the engine begins to suck in the combustible mixture, and the stop sphgan 28 opens, due to which the mixture continues to flow. FIG. 2 shows the first regulator (the preferred embodiment). The third nozzle 26 has a nozzle 42 which serves to regulate and screw on a corresponding tubular nipple 43 rigidly connected to the housing 1 of the pressure regulator. On the pipe 43 provides forked lever 44, the lower end 45 of which has a seal 46 and a threaded hole. The seal 46 is hollow and, due to possible oscillations, is provided with a small stop 47 for the spring 32, the free end of which is in contact with the locking member 28, working in conjunction with the third nozzle 26. In this case, the locking member 28 is a washer with an annular groove 48. the curved lever 49 simultaneously operates a pin 31, which is held by a fork lever 50, rigidly connected to the fork lever 44. Such a design provides for balancing the lever with a certain degree of freedom, and to such an extent that the displacement of the lever 30 has no effect on the locking member 28 — a valve that evenly protrudes along the edge of the third nozzle 26. Moving the lever 49 clockwise causes the locking member 28 to move against the action of the spring 32 and the formation of a gap of constant width relative to the edge of the third nozzle 26, through which the mixture enters an additional cavity 18. In the diagram (FIG. 3) a reel 51 is shown, which is connected to the spark plug by means of the high voltage conductor of the distributor 52. The output of the replacement circuit 53 is connected to the winding of the electromagnet 16. The bark of which is kinematically connected to the core 41 of the valve 15. The retarder is powered through a switch 54, which in the case of a car engine consists of a switch for starter and ignition. The closure of the switch 54 communicates the potential to the first transistor 55, the base of which is connected, for example, by inductive or capacitive coupling 56 to the high voltage conductor 52 of the ignition coil 51, the emitter of transistor 5.5 by means of resistance 57 is connected to transistors 58 and 59, which together with diodes 60-62 The capacitors 63 and 64 and the resistances 65-67 control the power supply to the winding of the electromagnet 16. Thanks to the electromagnet 16, for some predetermined period of time before the start of operation of the Ignition reel 51, i.e. before the engine starts, it receives power and, as a result, further excitement due to the impact of the circuit 53.
    To start the engine, first close the switch 54 to start the engine. work moderator, whereby the transistors 58 and electromagnet 58. 16 are supplied with power for a certain time, for example, for 2 s, the fuel comes from chamber 37 through the second nozzle 13 and the saddle 39 in cavity 3 and 18, into the engine intake pipe. The started engine continues to operate as high voltage through inductive or The capacitive coupling 56 acts on the transistor 55, which closes the power supply circuit of the electromagnet 16, after the electronic retarder circuit is disconnected.
    During normal operation, the engine in the output cavity 3 creates some vacuum, which is transmitted through the first channel 11 to the input cavity 2. And by deforming the first membrane 5 causes a proportional opening of the locking member 28. Flowing out of the third nozzle 26
    0, the mixture, then exiting through the saddle 39, creates in the additional cavity 18 some pressure, under the action of which a metered amount flows through the third channel 25
    5 fuel The stream of fuel coming out of the second nozzle 13 flows along the coaxially located second channel 12 into the first channel 11 and acts on the membrane 8. This stream
    -. of one degree or another is divided between the first channel II and the output cavity 3. The deformation of the membrane 8 occurs as a result of the pressure difference in cavities 3 and 9, which in
    in turn, they correspond to the pressures provided in the intake manifold above and below the air filter. This creates the best conditions for powering the engine: the engine responds directly to a sudden overload, and proportionally to this overload, the normal condition is restored again.
