Rotary energy converter

In a rotary compressor wherein is provided a fixed housing provided with a cylindrical chamber for receiving and operably supporting a primary rotor, a circular primary rotor mounted within the cylindrical chamber of said housing for rotation about its own fixed axis, said primary rotor being provided with a symmetrical diametrically-extending parallel-sided chamber, the opposed ends of said parallel-sided chamber being closed by arcuate end walls each of which is provided with an end port extending into open communication with the exterior of said primary rotor, and a circular secondary rotor operably positioned within the chamber of said primary rotor between the parallel sides thereof, said secondary rotor being eccentrically affixed to a drive shaft operably mounted in said housing for rotation about an axis disposed in parallel offset relation with respect to that of said primary rotor;

• said housing being provided with an inlet port extending into open communication with one end of a medianly disposed inlet channel formed in the wall of said cylindrical chamber in the general plane containing said end ports and extending around a substantial portion of the periphery of said primary rotor, said housing being provided with a discharge port separated from said inlet port and extending into open communication with one end of a medianly disposed discharge channel, complementary to said inlet channel, formed in the wall of said cylindrical chamber and extending around a portion of the periphery of said primary rotor generally opposite to that portion thereof embraced by said inlet channel, said secondary rotor being provided with a slip-ring seal mounted on the periphery therof, the mid portions of the parallel walls of said parallel-sided chamber being provided with seal means for operative engagement with said slip-ring seal, said compressor also including one or more additional symmetrical diametrically-extending parallel-sided chambers provided with opposed end ports and having their longitudinal axes successively angularly offset with respect to that of said first mentioned parallel-sided chamber, said additional parallel-sided chambers being separated from said first mentioned parallel-sided chamber and from each other by median webs each having a central aperture whereby to provide clearance around said shaft;
• and an additional circular secondary rotor operably positioned within each said additional parallel-sided chamber between the parallel sides thereof, each of said additional secondary rotors being eccentrically affixed to said shaft in successively angularly offset relation with respect to said first mentioned secondary rotor;
• said inlet and discharge channels each having a width sufficient to span all of the said end ports of all of the said end ports of all of the said parallel-sided chambers.

A rotary compressor including a fixed housing provided with a cylindrical chamber for receiving and operably supporting a primary rotor, a cylindrical primary rotor mounted within the cylindrical chamber of said housing for rotation about its own fixed axis;

• said primary rotor being provided with a first symmetrical diametrically-extending parallel-sided chamber having arcuate end walls each of which is provided with an end port extending into open communication with the exterior of said primary rotor, said primary rotor being provided with a second symmetrical diametrically-extending parallel-sided chamber having arcuate end walls each of which is provided with an end port extending into open communication with the exterior of said primary rotor;
• said second parallel-sided chamber having its longitudinal axis oriented at an angle with respect to that of said first parallel-sided chamber and being separated from said first parallel-sided chamber by a median web having a central aperture to provide clearance around a drive shaft;
• first and second secondary rotors respectively operably positioned between the parallel walls of said first and second parallel-sided chambers and being eccentrically affixed to a drive shaft extending through the aperture of said median web and journalled in said housing for rotation about an axis disposed in parallel offset relation with respect to the axis of rotation of said primary rotor;
• said housing being provided with an inlet port extending into open communication with one end of a first stage inlet channel formed in the wall of said cylindrical chamber in the general plane containing the end ports of said first parallel-sided chamber and extending around a substantial portion of the periphery of said primary rotor, said housing being provided with a first stage discharge channel complementary to said first stage inlet channel and extending around a separate portion of the periphery of said primary rotor;
• said housing being provided with a second stage inlet channel formed in the wall of said cylindrical chamber in the general plane containing the end ports of said second parallel-sided chamber and being substantially coextensive in length with said first stage inlet channel, the intake end of said second stage inlet channel being chamber-connected to the discharge end of said first stage discharge channel, said housing being provided with a second stage discharge channel complementary to said second stage inlet channel and extending around a separate portion of the periphery of said primary rotor in general association with said first stage discharge channel, said second stage discharge channel having one end extending into open communication with a discharge port formed in said housing.
