Translated by google from German :-
| Quote: | By the influence of the gas oscillations on the inlet procedure not only the filling of the crankshaft housing, but also the gemischzusammensetzung change with the number of revolutions. If the number of revolutions falls with opened carburetor cross section under the number of revolutions, at which the best filling is reached, then mixture from the crankshaft housing flows back into the intake. The flowing back mixture is enriched again there now with fuel (it becomes fatter). An elegant solution of this problem represents the installation of a simple swinging area. The swinging area is connected by a pipe with the intake. If the piston continues to close the einlassschlitz during the downward movement ever, or which diaphragm tongues brake by the sinking difference of pressure the gas flow ever more strongly, the running back wave has to flow now the possibility into the connecting tube and diminish the flow energy. Thus the influence of the running back wave on the carburetor decreases. Practice shows that the gemischzusammensetzung almost remains over the entire speed range equal, only at very low numbers of revolutions drops it somewhat. The effective range can be varied however over a changed length of the connecting tube. The use of a swinging chamber makes a leaner mixture attitude possible and leads to a measurably smaller consumption in the middle and lower speed range result: a swinging chamber brings a better filling of the crankshaft housing, with continuous gemischzusammensetzung over almost the entire speed range. In addition gasoline consumption is lower in the lower and middle speed range. SCK TIP: Straight one with that very long sucking in of you times of the long rockshaft, which for the PX is available can without the assembly of a Boost Bottle of the carburetors is hardly cleanly co-ordinated (valid only for rotary valve price increase). A constant fat, particularly in the sliding enterprise, ruin any layer of run culture. The Boost Bottle eliminates this problem almost completely. For large volume engines the Polini Boost Bottle, since this exhibits a sufficiently large chamber volume is recommended, in order to compensate the resulting mass of gas. The length of the suction hose from the intake to the Boost Bottle determines the number of revolutions with that the chamber supporting works. We recommend with o.g. To leave case (long rockshaft, 28-30mm carburetor) the hose in its original length. |
Sounds like it acts as a capacitor for the fuel/air mix, smoothing out delivery when shutting off/reopening the throttle.

seen one on a RD350, single can with two pipes at each end going to the carb, when the throttle was shut off the wasted fuel air mixture would go to the can intesed of going out the exhaust so next time the throttle was opened there would be a "boost" of midrange acceration
