Abstract
Abstract An apparatus for generating energy from a flowing medium comprises a frame with a rotatable rotor, being composed of two parallel wheels in between which blades are arranged, said rotor being so constructed that the blades maintain a fixed position relative to the frame and therefore, to the flowing medium, because of both wheels making an obtuse angle with a line connecting their centers, while the blades are pivotally connected with the wheels.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
135 words
Apparatus for generating energy from a flowing medium, comprising a frame, a rotatable rotor supported on the frame, the rotor being comprised of two spaced apart, parallel wheels, oblong blades being suspended between the wheels, connection elements supporting and suspending the blades between the wheels and rotatably mounting the blades to the wheels, each wheel having a respective axis of rotation and the axis of rotation of each wheel making an acute angle (α) with a connection line between the centers of the wheels, each blade covers a corresponding angle with the part of the respective connection element that is rotatably mounted in the wheels, so that the blades maintain a fixed position relative to the frame during the rotation of the rotor, and a cover partially screening off the rotor from the flowing medium.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
29 words
An apparatus according to claim 1, wherein each blade comprises an oblong frame in which a number of parallel sheets are arranged equidistantly and are supported in the frame.
Claim 4
Dependent Claim
39 words
An apparatus according to claim 1, further comprising a plate mounted in the frame, the plate and the cover are together so shaped as to form a channel for the flowing medium, which channel converges wedge-like toward the rotor.
Claim 5
Dependent Claim
25 words
An apparatus according to claim 1, wherein either end of each blade is pivotally the respective connected with connecting element arranged in the adjacent wheel.
Claim 6
Dependent Claim
41 words
An apparatus according to claim 1, wherein spindles are defined at the centers of the wheels, between the centers of the wheels a hollow bar is mounted, the bar, on either side, being connected with the spindle of the corresponding wheel.
Claim 7
Dependent Claim
14 words
In an apparatus according to claim 5, wherein the bar has an ellipse-shaped cross-section.
