There is a sleeve around the valve tube that directs the flow of air.
Proper adjustment of that sleeve in imperative for easy breathing with
no freeflow.

Just my $.02

The sleeve has been adjusted till it just prevents continous free-flow
after the purge button is released, which is what I understand the
correct setting to be.

At very low air flow when breathing very gently (as I do mostly), the
venturi effect would surely be quite small.
