    • 专利摘要:
    A compensation apparatus for a carburetor having a first opening in the wall of the air intake passage near the edge of the throttle valve so that the first opening is positioned upstream or downstream of the throttle valve depending on the degree of opening thereof. A second opening is similarly provided in the wall of the air intake passage so that it is positioned downstream of the throttle valve, at least when the first opening is positioned upstream thereof. A connecting passage joins the first and second openings, and a further passage supplies fuel to the connecting passage. Air is reversely bled through the first opening and fuel is discharged through the second opening, whereby fuel shortage due to response delay in the transitional region between the low-speed and high-speed phases, or in the transitional region between the idling and the low-speed phases, is prevented.

    (54) CARBURETTOR
    This invention relates to the field of engine building, in particular to carburetors for internal combustion engines.
    Known carburetors containing 5 housing with mixing chamber, throttle, float chamber, idling system with transitional holes, fuel jet for fuel supply, compensatory JQ device made in the form of fuel chamber and first and second holes located in the wall of the mixing chambers and communicated with the fuel chamber, respectively, through the first and j5 second channels, the second channel being connected to the lower part of the fuel chamber
    A disadvantage of the known device 20 is that in general-type carburetors it is difficult to achieve an exact ratio of the fuel-air mixture due to the lack of fuel, especially in transitional conditions between low and low (5
    high-speed and high-speed engine work.
    The aim of the invention is to reduce the inertia in the fuel supply during transient conditions.
