no one really explained how this works. they have said what it does, but what I am interested in is the theory of operation. If it puts the water over the coffee more slowly (as it says in the manual), how is this done? I can think of a couple of ways: modulate the heating element that casues the "perk" action. all coffee makers work the same way (that I have seen). They heat the water in a tube that runs along side the heating element. The water gets hot enough to produce pressure in the tube and force a check valve open leading up a tube to the dispensing head. the water cools off a bit but the check valve keeps it from coming back down into the heating tube. OK, so how does one slow this process down? I can think that they may put an orifice which is variable size leading into the heating tube. I can also think that they might reduce the wattage of heating tube so that each time it refills after a perk, it takes longer to get it hot enough for the next perk. Well, the reason I am asking about this, is because what ever method they use (my ideas or any other) there would be a possible negative effect on the taste of the coffee, the efciency of the machine, or ability for the machine to keep the coffee hot. So, any other handymen out there that have reverse engineered one of these coffee makers who can explain how it works?
