Abstract
A current generator for a swimming system may include multiple entrainment pumps that discharge a flow of water into a pool. The entrainment pumps may each have a nozzle, a venturi and an entrainment inlet. In use, the flow of water from the nozzle into the venturi causes water at the entrainment inlet to flow into the venturi along with water from the nozzle. Each entrainment pump is arranged such that the fluid that flows out of the venturi passage is directed within a main passage, and the flow from multiple venturis may be combined and may be directed at least partially against the force of gravity before that fluid is directed out of the main passage outlet and into the pool. In at least some implementations, the fluid flows for at least one foot between the venturi and the main passage outlet.
