A centrifugal separator for separating gas bubbles from a liquid incorporates a spiral liquid passage with inlet and outlet ends as defined by a top plate, a bottom plate and a strip spirally coiled between the plates and otherwise constructed so that by utilizing the low specific gravity of the bubbles and centrifugal force acting thereon, the bubbles are directed into a bubble trapping compartment for removal.

A centrifugal separator for separating gas bubbles from a liquid in which such bubbles are trapped comprising: a flow structure having an inlet for admitting a liquid having entrapped gas bubbles and comprising a top plate, a bottom plate parallel thereto and a strip spirally coiled between and having the edges thereof joined to said top and bottom plates, the inner end of said strip being joined to the innermost turn of said strip so as to define between the inner and outer ends of said strip a spiral passage having inlet and outlet ends and a central axis in a single plane and being of substantially uniform rectangular cross section and for a major portion of its length being bounded by imperforate walls defined by said plates and strip and confined between parallel planes defined by said plates and parallel to said single plane, whereby to subject the liquid received through said inlet to flow pattern forming a vortex and in which flow pattern separation is achieved by the liquid of relatively high specific gravity being centrifugally forced toward and confined by radially outward portions of said passage during travel along a major portion of the length thereof enabling the said gas bubbles of relatively low specific gravity to be forced toward and confined by radially inward portions of said passage during travel along said major portion of the length thereof, said inner end of said strip comprising a radially inward portion and being partially cut out to provide an opening in said radially inward portion near the outlet end of said passage so as to form a bubble trapping compartment adjacent said opening, said compartment communicating with a first outlet for removing bubbles separated from said liquid after travel along said major portion of the length thereof, and a second outlet communicating with said outlet end of said passage for removing the liquid free of those bubbles removed at said first outlet.
