Abstract
A quiescent zone fluid filter. A reservoir communicates via upstream and downstream communication ports with a fluid flow tube. At the upstream communication port, liquid flowing in the fluid flow tube enters a quiescent zone of the reservoir, whereupon particles therein descend. The liquid then rejoins the fluid flow tube at the downstream communication port free of particles therein. The quiescent zone fluid filter is advantageously implemented within a fluid flow control valve, as for example at the valve barrel of a barrel valve.
