| 摘要 | A pump includes a housing that contains a liquid, and a rotor including a plurality of blades extending radially from a shaft, and defining a conical space. A port member is disposed within the conical space. The port member defines an inlet port in communication with a low pressure region, a discharge port in communication with a high pressure region, and an anti-cavitation port in communication with a fluid supply having a pressure between the low and the high pressure regions. Each pair of adjacent blades cooperates with the liquid and the port member to enclose a variable volume bucket, wherein rotation of the rotor selectively positions a bucket in an inlet position adjacent the inlet port to draw in fluid, in an anti-cavitation position wherein the bucket is adjacent the anti-cavitation port and fluid is admitted into the bucket, and a discharge position wherein the bucket is positioned adjacent the discharge port to discharge fluid. | ||||||
