Abstract
Liquid deaeration apparatus having a deaeration chamber, a positive displacement pump downstream of the deaeration chamber, a first flow restrictor upstream of the deaeration chamber, a low pressure sink connected to an air outlet of the deaeration chamber, and a second flow restrictor between the pump and the liquid outlet of the deaeration chamber to raise the pressure at the liquid outlet above that at the air outlet to cause volatilized gas to be removed via the air outlet of the deaeration chamber.
