Question Regarding the Pump

[Chris1967]

Dear Brothers,
I would like to know how the pump actually works internally—from a technical standpoint. I haven't been able to find anything about this online. I assume the underlying principle is the same for all implants. In my view, there must be a valve installed inside the rectangular housing; but how is everything connected to one another? Perhaps you guys can shed some light on this. Is there a genius among us who can offer some insight?
