Rotary engine with deformable rhombus

MRLD

The rotary engine with deformable rhombus is the French name and not patented, of the rotary driving 4 of Mr. Ambert or the Quasiturbine of the team of Doctor Saint Hilaire.

Mr. Ambert showed that the four ends of a rhombus, length on sides fixes, can follow the same closed continuous parametric curve. This curve is made up of two arcs of circles and two curves called sheet of clover. These curves are dependant since their connection is continuous. They depend on two parameters, one giving of the shapes of the ellipse to the “ellipse” on board right and passing by the circle. The other is a parameter of homothety (does not change the form but just the size of the unit).

The team of Doctor Saint Hilaire, with her, determined a contour “Holy Hilaire” representing the trajectory of four center each one centered on an end of the rhombus. This rhombus describing a trajectory of Mr. Ambert.

The advantages of this engine are very well reported in the article relating to the Quasiturbine. Its disadvantages are reported. The sealing and the recovery of the couple of exit are difficult to solve.
