The invention relates to a circulating air duplex diaphragm regulator, the the engine to the normal gas-air mixture air for better combustion of fuel without changing the normal carburetor setting and without overheating the engine. Various designs are already known, e.g .: by adding several recirculating air regulating screws on the carburetor of additional fuel, by opening the throttle valve in the replenishment, as well as by retarded ignition in the replenishment and Injection pen into the exhaust manifold through air pump and shut-off the idle jet in the replenishment. In the years 1920-1930 there have already been additional air supplies in the intake manifold that could be regulated by hand in order to achieve better combustion of the fuel, but which were added irregularly and caused the engine to overheat and damage. To solve this problem, I have according to the invention a duplex diaphragm regulator for circulating air developed, which largely reduces the toxic exhaust gases and the additional air for better combustion the fuel in the Mgtor regulates as follows without the engine

In Figure 1 is a. Carburetor 1 shown in section with mounted Circulating air duplex diaphragm regulator 9, with a retaining bracket 10, is attached to the carburetor 1 with a screw 19 and with the lever 8, linkage 4, lever 7, with the throttle valve shaft 23 is in connection to open and close the circulating air duplex shutter.

It is known that when the throttle valve 2 is opened in the direction of arrow 3, not only fuel is sucked in from the idle bore 6, but also from the bypass bore 5 and partly from the full-load nozzle via the main injection 32. This mixture is too rich, especially in the lower driving range . For this reason, it is necessary to meter air below the throttle valve 2 to the gas-air mixture through the circulating air duplex diaphragm regulator as follows: When opening the throttle valve 2 in Pfein direction 3, the levers 7 and 8 and the linkage 4, the duplex Rotary aperture 24 »which is firmly connected to the shaft 23a, with the ^{elongated 1} -inch 12 in the direction of arrow 3a in the air regulator housing 9 and 9a in Figure 1 to the elongated hole 11 of the fixed aperture 25 when accelerating and gives the Laoglochöffnrng 11 in Figure 1 gradually release for additional air suction B _e utilization of the engine, while the long pool cover each other for the Nachsohublufteinlaß 13a and 30 (closed). The air that is passed through the air filter 22, FIG

sucked in, the oil vapors are mixed with it Gasoline vapors from the crankcase, which the air filter 22 are fed in the known manner 21 and in the direction of arrow 20 Figure 1 about the carburetor 1 and the circulating air duplex diaphragm regulator 9 and 9a in Figure 2 sucked in Hindu roll for better combustion of the fuels in the engines.

The two elongated holes 12 and 11 one above the other (see also Figure 7), then the full additional air passage in the mechanically controlled circulating air duplex diaphragm regulator Figure 2 is released for Admixture of the air in order to achieve a better mixed combustion in the to reach the lower travel range.

If the throttle valve 2 is opened further in the direction of the arrow 3 until it is full, then the lever 7, linkage 4 and lever 8 on the driver shaft 23a in FIG. 2 also the rotatable duplex panel 24 with the elongated hole. 12 further rotated in the direction of arrow 3a, so that the elongated hole 12 in the adjustable and lockable panel 25 is gradually covered again (see Figure 8) as the two elongated holes 11 and 12 cover each other (close), so that no air over the circulating air Duplex aperture control can be inspected. This has the advantage that with increasing load up to full load of the engine, the normal permissible gas-air mixture, as prescribed by the engine manufacturer, sucks in so that the engines are not overheated by installing the mechanically controlled circulating air duplex diaphragm regulator.

Oil and gasoline vapors are also sucked in from the crankcase via the throttle valve air gap * These rich gases cause poor combustion. In order to improve this poor combustion, the mechanically controlled circulating air duplex diaphragm regulator is equipped with a second circulating air supply on the rotatable duplex diaphragm 24 in FIG 26 and an adjustable valve seat ^{insert · 31 for the F Q} , which is tensioned. Each time the throttle valve 2 in FIG. 1 and the Dupler.blendc 24 in FIG. 2 are closed against the direction of the arrow 3a, the elongated holes 11 and 12 overlap each other except for a small air gap 12a in FIG. 6 for additional idle air intake. If the motor is powered by the car, it sucks in the ball valve 14 via the second air circulation system on the duplex rotary screen 24 in FIG free. The sucked-in air is sucked into the intake manifold via the elongated holes 13a and 30 in the direction of arrows 27 and 17a, and below the throttle valve 2 in the direction of arrow 33 for admixture with the rich gas-air mixture. This means that better combustion is achieved even in the aftertaste. The air required as a result for the various ccm engine contents is determined by a throttle screw in the intake duct 17 for air passage, also the compression spring 26 is on the opening side. the valve ball I4 with the

The adjustable bezel 25 in Figure 3 with the two elongated holes 11 and 30 is on the lever 28 in two directions of arrows 29 to the closed throttle valve 2 and to the closed duplex screen 24 · adjustable to an air slot 12a in FIG. 6, for additional air intake to the normal idle gas-air mixture. A recess 10 in FIG. 2 is screwed into the adjustable and lockable panel 25, when screwing together the two controller housing parts 9 and 9a, the adjustable and lockable diaphragm 25 is clamped, while doing so the result is an annular groove 10a and the duplex rotary shutter 24- is guided in this annular groove 10a and can be triggered by a flashback do not evade.
