Abstract
An apparatus for removing liquid from an air liquid separator is disclosed having a rotatable chamber in communication with the liquid collecting portion of the air-liquid separator such that liquid from the separator may enter the interior of the chamber. A drive motor is associated with the chamber to rotate the chamber such that water collects on the interior of a peripheral wall. A pitot tube extends into the interior of the chamber and has an inlet end adjacent to the inside of the peripheral wall such that water may enter the tubes as the chamber rotates. The other end of the pitot tube extends exteriorly of the apparatus. Rotation of the chamber will cause water to enter the pitot tube and pass through the tube to the exterior of the device.

Apparatus for removing liquid from an air-liquid separator having a liquid collecting portion and an air discharge tube, the device comprising:
- a) means defining a chamber having a peripheral wall and an interior space in communication with the liquid collecting portion of the air-liquid separator such that liquid in the liquid collecting portion may enter the interior of the chamber;
- b drive means operatively associated with the chamber so as to rotate the chamber about an axis to thereby cause liquid within the chamber to be displaced against the peripheral wall;
- c) a pitot tube having a first end located within the chamber adjacent to the peripheral wall such that liquid collected on the peripheral wall will pass through the pitot tube as the chamber rotates, and a second end located exteriorly of the chamber and the air-liquid separator;
- d) means operatively associated with the chamber means to draw liquid from the liquid collecting portion of the air-liquid separator into the chamber as the chamber rotates wherein the chamber means has an end wall and wherein the means to draw liquid into the chamber comprises a plurality of radially extending vanes protruding from the end wall into the chamber means;
- and,
- e) air bleed passage means communicating with the interior of the chamber to allow air to pass from the interior of the chamber means wherein the air bleed passage means is operatively connected with the air discharge tube.
An air-liquid separating system comprising:
- a) vortex-type air-liquid separator having an air-liquid mixture inlet oriented so as to introduce the air-liquid mixture into the air-liquid separator along a generally tangential path, an air outlet and a sump portion for collecting separated liquid, and,
- b) means to pump the liquid out of the sump portion comprising:
- i) means defining a chamber having a peripheral wall and an interior space in communication with the liquid collecting portion of the air-liquid separator such that liquid in the liquid collecting portion may enter the interior of the chamber;
- ii) drive means operatively associated with the chamber so as to rotate the chamber about an axis to thereby cause liquid within the chamber to be displaced against the peripheral wall;
- and,
- iii) a pitot tube having a first end located within the chamber adjacent to the peripheral wall such that liquid collected on the peripheral wall will enter and pass through the pitot tube as the chamber rotates, and a second end located exteriorly of the chamber means and the air-liquid separator.
