Abstract
A fluid system is disclosed having a passage with a reduced diameter orifice. A wire extends into the orifice and is reciprocated therein to simultaneously clean and meter a predetermined fluid flow through the orifice. Automatic reciprocating movement of the wire is accomplished by differential pressures acting on the wire on opposite sides of the orifice.
