Abstract
PURPOSE: To extend life of the seal between the air chamber and the oil chamber, by forming an air chamber between the oil chamber and the pump room and fitting a flexible ring in the partition between the air chamber and the oil chamber.
CONSTITUTION: The central portion of the partition 14 between the air chamber 5 and the oil chamber 4 is concaved in a suitable fashion, and the air chamber 5 is adapted to communicate with the pump room 6 via the rear vanes 7a mounted on the impeller 7, and, further, the one side of the peripheral portion of the air chamber 5 communicates with the ejector air intake room 12 through the intake pipe 16. A flexible ring 17 is formed in a cone shape with a central opening, and flexibly fitted on the pump shaft 2 at the central concave portion in the partition 14. This ring 17 rotates without contact with the partition 14 during the pump operation, but, while the pump is stopped, it is pressed on the partition 14 to be attached on it by the water pressure outside the pump that is loaded through the ejector main body 13 and the pump suction port 9, etc. Consequently the ring prevents the invasion of counter flow and lengthens life of the seal.
