the apparatus containing section vi of the longitudinal opening f in coil e 6 liquid particles 1 which may have a density that is for example one thousand times heavier than the density of gas particles 2 are launched by the centrifugal forced caused by the angular velocity component of the fluid marked with the arrows k towards the periphery p of the separation housing furthermore the gas particles 2 have crossed the longitudinal opening and are conveyed upstream inside the main pipe fig1 highlights the fact that the mixture of liquid and gas 1 2 descending along the coils of the helix e becomes increasingly more concentrated with centrifuged liquid particles 1 as well as increasingly lacking in gas particles 2 that ascend upstream through the intake inside the main pipe t the black spheres 1 which indicate the liquid descending along the helix as pointed out by the arrows k are launched by the centrifugal force against the walls of the separation housing p while the white spheres 2 which indicate the gas phase go through the continuous opening f and are pulled upstream by aspiration as pointed out by the ascending arrows h of fig1 with reference to fig3 the edge b of the opening f which is downstream from the descending helical fluid path is shaped as a spiral pointing towards the center of pipe t the aspiration effect is improved by this fact the clarity of fig1 and 3 highlights the structural simplicity and functionality of the apparatus of the present invention the invention of course allows for several variations in its practical embodiments as far.
