Embodiment Construction
[0021] exist figure 1 In the liquid ring vacuum pump shown, the impeller 14 is mounted eccentrically in the pump housing 20 . The liquid inside the pump is driven by the rotating impeller 14 and forms a liquid ring extending radially inward from the outer wall of the pump casing 20 . Due to the eccentric mounting, the blades of the impeller 14 protrude into the liquid ring to different depths depending on the angular position. The volume of the chamber 22 enclosed between the two vanes thus changes. The liquid ring thus acts as a piston which moves up and down in the chamber during the revolution of the impeller 14 .
[0022] From the inlet 16 a tube leads into the interior of the pump in which the impeller 14 rotates. The tubes open in the region where the blades of the impeller 14 emerge from the liquid ring, in which region the chamber enclosed between the two blades thereby widens. Due to the enlarged chamber, gas is sucked into the chamber through the inlet 16 . Afte...
