Liquid degasser with self-throttling exhaust orifice

摘要

A centrifugal (cyclone) separator for extracting entrained gas from a liquid which includes a cylindrical member carrying vanes which extend into the vortex created by fluid swirling through the separator. The cylindrical member is mounted for rotation about a fixed member in response to action of the fluid on the vanes and relative motion between the cylindrical member and the fixed member opens and closes a valve in the gas escape route to shut the valve when the quantity of gas in the votex is low enough to expose the vanes to the liquid.
