摘要： A compressor oil pump with integral contaminant collector and helical vane for improved pumping efficiency. A generally cone-shaped pick-up tube is adapted to be attached to the lower end of a hollow rotatably driven vertical shaft for rotation thereby about its longitudinal axis. The lower end of the pick-up tube includes an inlet opening which extends into a reservoir of oil. An annular contaminant collection groove is disposed circumferentially within the wall of the pick-up tube forming a pocket. This groove collects and retains contaminant particles contained in oil which is swept up the tapered interior surface of the tube due to the centrifugal force developed by its rotation. The helical vane is provided in the interior of the pick-up tube to increase its pumping efficiency. The vane acts to accelerate the oil to the rotational speed of the pump, thereby improving the volumetric flow output from the pump.
