Patent ID: 8721310

Claim:
A rotary motor for compressible media comprising: an impellor and a stator mounted between two mutually coupled and concurrently mounted bearing plates in which is mounted a driving shaft of the impellor, the driving shaft having a rotary piston mounted thereon in a chamber of the stator, the stator being equipped with sealing lids, wherein the rotary piston has an elliptical crosscut and is mounted into the chamber, the chamber being a symmetrically shaped triangular chamber equipped with rounded peaks, each of the rounded peaks being equipped with at least one port for an entry and an exit of the compressible media, the rotary piston being mounted such that a lengthwise axis o p of the rotary piston is coaxial with a driving shaft axis, the stator rotating in a circular movement in a direction opposite of the rotary piston, wherein the rotary piston rotates at a parallel advance of all points of the stator along a circle with an eccentricity radius e and is moved in relation to a lengthwise axis o s of the chamber of the stator of the value of the eccentricity radius e, wherein one of the bearing plates is on the driving shaft mounted central cog wheel, the central cog wheel having three satellite cog wheels mounted on a perimeter thereof, which are firmly mounted on pegs pivoted in each of the bearing plates and coupled with the stator by drive pins fixed in the stator and each of the drive pins are spaced the eccentricity radius e from a peg axis.
