Patent ID: 7166147

Claim:
Process for separating and exhausting gas bubbles from a continuously flowing liquid which contains gas bubbles during passage thereof through a deaeration chamber between an inlet point and a discharge point, comprising the steps of: locating the deaeration chamber between a flow of liquid at the inlet point and a flow of liquid at the discharge point which run at least essentially in the same axial direction, providing a lower pressure on the outside of the deaeration chamber than in the deaeration chamber, providing the deaeration chamber with at least a section of at least one wall made of a gas separation material which repels liquid, but which is permeable to gas, causing the liquid to flow from at least one of the inlet to deaeration chamber via an inlet filter and from the deaeration chamber to the outlet to pass through a discharge filter, the at least one filter being made of a material which absorbs the liquid and which forms pores or small channels, matching the delivery pressure of the liquid, the flow resistance of the gas separation material of the deaeration chamber and the liquid absorbency of the at least one discharge filter to one another such that the gas bubbles which are contained in the liquid, to a large extent, escape to the outside through the wall, causing the flow path of the liquid to be deflected between the inlet point and the deaeration chamber and between the deaeration chamber and the discharge point so that the liquid is deflected from the axial direction, first radially outward into the deaeration chamber and then radially inward back into the axial direction for separating the gas from the liquid by the gas separation material independently of the position of the deaeration chamber.
