Abstract: A power generation device and method using organic working fluid for circulation without pump and valve are invented, the principle is able to be called flash jet natural cycle. The flash injection tube, the magnetic sphere motion tube and the storage tank are connected to form the main loop. The finned tube and the storage tank are connected to form the cooling loop. The working fluid is heated in the flash injection tube by low-temperature heat source, and is cooled in the finned tube by air or water. The gravity and flash force jointly drive the flash jet natural cycle. The lower magnetic ball acts as a one-way valve for supplying liquid to the flash injection tube. The upper magnetic ball acts as a valve and a rotor driven by the flash force and gravity to move linearly and produce electricity.

Abstract: A method for collaboratively constructing a column envelope profile of two flanks of a star wheel tooth includes steps of: determining a tooth width B of a star wheel according to a diameter of the star wheel and a dimension of a root circle; thereafter, geometrically representing positions and shapes of the two flanks of each star wheel tooth of the star wheel by two base columns having parallel axes and the same diameter; wherein: the axes of the base columns are parallel with a center line of the star wheel tooth; on a section of a tooth top of the star wheel tooth, a local projection of a first base column close to a front flank of the star wheel tooth is projected on a lowermost part of a projection of the front flank of the star wheel tooth; and a local projection of a second base column close to a back flank of the star wheel tooth is projected on an uppermost part of a projection of the back flank of the star wheel tooth. A center distance L between the two base columns, a diameter d0 of the base columns, the tooth width B of the star wheel tooth and an inclined angle λ of the flanks of the star wheel tooth at a pitch circle have a quantitative mathematic relationship.
