Claim 11

A gas-liquid separator as claimed in claim 8, wherein said screen guiding means consists of layers of screening material and extends along the length of said piping and including a third anti-vortex means wrapped about the outer surface of said piping within the confines of said layers of screening for reducing upward high speed streaming of flow along the outer surface of said piping in said screen guiding means.

Claim 12

An anti-vortex gas-liquid separator which is compartmentalized for eliminating high speed streams of gas-carrying liquid and comprising said gas liquid separator having an inlet passage extending into enlarged cup means presenting an impact surface for providing a back pressure on liquid flowing from said inlet passage to reduce the liquid flow speed and for reversing the liquid flow direction, said cup means opening into a first compartment of increased volume, screen guiding means surrounding said cup and extending along the length of said inlet passage spaced therefrom, first anti-vortex means in said screen guiding means for impeding the liquid flow path, said first anti-vortex means and screen guiding means for suppressing flow vortex resulting from the reversal in liquid flow direction, a second compartment of increased volume for the slow uniform flow of stream-free liquid, second anti-vortex means separating the first and second compartments and for providing an impedance against liquid flowing directly from said cup means into said second compartment, a liquid outlet in said second compartment for the outflow of gas-free liquid and a venting outlet in said first compartment for the escape of separated gas.
