9.2.5) BING constant depression carburetor type 64-3
See Pic. 15/16 and 17.
The BING constant depression carburetor type 64-3 is a cross-draft butterfly
valve carburetor with variable venturi, double float system arranged centrally
below the venturi, and a rotary valve type starting carburetor. It features a
carburetor piston W which is suspended from a roller diaphragm E and
projects into the venturi. It changes the smallest cross section (venturi) of the
venturi as a function of the vacuum at this point. By actuation of the throttle
valve Q the depression is influenced and the carburetor piston is moved. The
throttle valve diameter is 36 mm (1.42 in.).
When the fuel has reached a specified level in the float chamber, then the
floats close the needle valve R via the float bracket thus preventing any
further supply of fuel.
