Abstract:
1. An apparatus for converting kinetic energy of a fluid flow in a fluid basin into any useable energy, the apparatus adapted to be submerged into the flow and maintained within a path of the flow to produce the useable energy and comprising: a runner means for receiving the kinetic energy, the runner means being rotatable about a central axis, the axis being in an intended operative position horizontal and across of a direction of the flow; a shroud means supporting and guiding the runner means for rotation about the axis runner and a means for controlling the receiving and transferring of the dynamic pressure; a means for maintaining the shroud means and the runner means in the position; a means for generating the useful energy; where the runner means comprising: a kinetic energy—transferrer hub member supported by the shroud means for rotation about the axis and adapted to support and guide components of the runner means for rotation about the axis and capable of being engaged with the generating means; and a plurality of kinetic energy—receiver blade members distributed around the hub member and extended along and between opposing edges of the hub member and connected to the hub member for pivoting about a connecting axis, the connecting axis being within the hub member and the blade member and parallel to the rotating axis, between working lower positions below of the turning axis and radial in relation to the connecting axis where the blade can receive the dynamic pressure of a lower oncoming flow in a direction remote from the rotating axis and transfer a rotating moment being risen about the axis to the hub member to cause the runner means to rotate with the blade member in the direction, and non-working upper positions above the rotating axis and tangential in relation to the connecting axis, wherein the runner means further comprises a drive means for effecting movement of each of the blade members about the corresponding connecting axis in the finishing radial position in a direction opposite to the direction of the oncoming flow to effect prolongation of applying by the blade member the moment to the hub member.
