ABSTRACT:
A machine for allowing different fluid or gas flow rates in different directions through a conduit with a freely pivotable valve element, and a valve element stop so as can provide for limited flow of a fluid or gas in one direction and full flow in the reverse direction, also allowing a feed pump to pump against its own head pressure. This permits a smaller reservoir to be used in cistern systems while not reducing pump run times below the minimum required but still allowing full flow in the opposite direction out of the tank to the end user.
