Reciprocating component-free kinematic motion apparatus for transforming pressure variations of a fluid operating in cyclically variable volume toroidal chambers into a mechanical work on a rotary axis and engine including said apparatus

摘要

In a cat and mouse type apparatus for transforming volume variations of a plurality of chambers into a rotary motion of an axis, all of the driving mechanism is housed in a cylindric cavity coaxial with the driving axis, between the cylindric cavity, a smaller diameter inner coaxial cylinder and two discs perpendicular to the axis, a toroidal cavity in which are housed rotary pistons, each longitudinally traversed by an axis and having a circular sector in cross-section shape, the rotary pistons rotating to form cavities defined therebetween, also having a substantially circular shape in cross section, where the cavities cyclically change their volumes and an apparatus driving shaft is rotatively driven.
