    Abstract: An accelerator pump for a carburetor comprises a piston assembly inserted in a cylindrical well formed in a carburetor body, a link mechanism for actuating the piston assembly in response to movement of a throttle valve, and a tapered stopper. The piston assembly is separated from the link mechanism and engaged with it only when accelerated. The tapered stopper is inserted in a hole made in said carburetor body, which hole is perpendicular to the cylindrical well, passing through a hole made in the piston assembly. A gap defined between the tapered stopper and the periphery portion of the hole of the piston assembly determines the stroke of the piston assembly. Further, the gap is adjusted by axial movement of the tapered stopper. The tapered stopper is locked with sealing material after being adjusted so that any user can not re-adjust the tapered stopper.

    Abstract translation: 用于化油器的加速泵包括插入在形成在化油器主体中的圆柱形井中的活塞组件，用于响应于节流阀的移动而致动活塞组件的连杆机构和锥形塞子。 活塞组件与连杆机构分离，仅在加速时与其接合。 锥形止动器插入在所述化油器主体中形成的孔中，该孔与圆柱形孔垂直，穿过活塞组件中形成的孔。 限定在锥形止动件和活塞组件的孔的周边部分之间的间隙决定了活塞组件的行程。 此外，通过锥形止动件的轴向运动来调节间隙。 在调节后，锥形塞子用密封材料锁定，使得任何使用者不能重新调整锥形塞子。

    Abstract: A carburetor for combustion engines, having upstream of an arbitrarily operated throttle valve, an additional throttling element which is controlled automatically by a membrane unit operated by underpressure of vacuum in accordance with air flow. The additional throttling element controls a fuel jet by means of a needle. The discharge location of the fuel jet is at a point where essentially the same underpressure prevails as in the mixing chamber formed between throttle valve and throttling element. In an enrichment system for the heating phase the fuel jet is controlled by a needle whose variable position is determined by the position of a temperature-sensitive element via a lever, and the fuel quantity for acceleration is varied by means of a second membrane unit. The discharge location of this enrichment system is downstream of the throttling element. The second membrane unit may be actuated by underpressure and may have a pressure chamber closed by a movable membrane loaded by a spring. The pressure chamber has an outflow jet and the membrane operates a valve by means of a plunger.

    Abstract: A carburetor with an auxiliary accelerator-pump system including a diaphragm pump. The diaphragm pump includes a fuel chamber and a vacuum chamber which are separated by a spring-loaded diaphragm. The fuel chamber leads by way of a check valve to a fuel reservoir or float bowl in a carburetor and by way of another check valve to a pump jet or nozzle which is open into an intake passage in a carburetor, while the vacuum chamber leads to a vacuum take-off port open in the intake passage downstream of a throttle valve. The fuel chamber is further communicated by way of a temperature responsive valve means with the fuel reservoir, and this valve means is adapted to open, when an ambient temperature exceeds a given temperature level.

    Abstract: An auxiliary acceleration fuel feed device in an internal combustion engine used for a vehicle is disclosed. An auxiliary accelerator pump is provided for feeding an auxiliary acceleration fuel into the fuel supply passage of the engine in response to a decrease in the vacuum in the intake manifold. A vacuum control device in a vacuum conduit connecting the pump and the intake manifold is responsive to the engine temperature and the vehicle speed. The vacuum control device is arranged so as to close the vacuum conduit to prevent the supply of the fuel to the nozzle by the pump when the engine temperature and the vehicle speed is above respective predetermined levels.

    Abstract: The intake manifold of a carburetor of an internal combustion engine has between its air inlet end and its discharge end a throat portion and a butterfly valve adjacent the discharge end. First fuel injection means communicate with the interior of the manifold in the region of the throat portion for injection of fuel into the latter during normal operation of the engine, and second fuel injection means communicate with the interior of the manifold above and closely adjacent the butterfly valve for injecting additional fuel into the latter during acceleration of the engine.
