Abstract
In a circulating pool main body which defines a swimming pool or tank, a bottom partition wall and front and rear curved partition walls are disposed and spaced apart by a suitable distance from the bottom and the front and rear curved portions of the main body, thereby defining a water circulation passage having an outlet opening to an upper upstream end of the swimming tank or pool and an inlet at the upper downstream end of the swimming tank or pool so that only the upper water layer of the body of water in the swimming tank or pool is forced to flow. Furthermore, one or more swingable blades or vanes are attached to the outlet of the water circulation passage so that the flow rate of the flowing upper water layer in the swimming tank or pool and its direction may be varied.
