This is part one of my effort to explain the theory of operation of a common lock-and-cancel valve assembly. In the video, I use the term 'more air' and 'less air' a few times. It is, however, more accurate to say a 'larger' or 'smaller' mass of moving air. Also, while I didn't notice it at first, at times 0:44 and 3:41 you can actually see the Rewind valve start to open. It is at that moment that air rushes into the valve through the hole in the top of the valve and the hole in the side of the valve. (While you can't see it in the video, the same thing is happening to the Play valve.) And, the mass of that moving air is greater than the mass of the moving air pushing against the Play valve, which only has the one hole in the top of the valve block. So, the Rewind valve, which is now heavier due to the increased mass of the air, closes.
