20100143174 | Rotary Working Machine Provided with an Assembly of Working Chambers and Periodically Variable Volume, In Particular a Compressor - A rotary working machine is provided. The machine includes an assembly of working chambers with periodically variable volume disposed in a central block defining a stator. The inside surfaces of the stator direct a pendulum motion of one or more blade-type working elements disposed in respective one or more cylindrical sockets of a cylindrical rotator that is disposed within an interior of the camshaft form stator. The rotator is connected to an external prime mover for providing torque thereto. An angle of contact between a front cylindrical surface of the blade-type working elements and the internal curved space of the camshaft form stator defines a working chamber of variable volume, the working chamber of variable volume is connected during rotator revolution correspondingly with an inside pipe of a camshaft and an annular slot that is configured to evacuate compressed gas disposed within the working chamber of variable volume. The outline of a cross-sectional of opening of the camshaft form stator disposed in a vertical plane to with respect to an axis of the cylindrical rotator constitutes the equidistant line to a curve that is described on an immobile plane perpendicular to the axis of the cylindrical rotators by a Radziwill curve. A defined relationship exists between the rotation angle of the cylindrical rotator and the deflection angle of an axis of the working element/ | 06-10-2010 |
20110135525 | NON-ECCENTRIC ENGINE - The present invention is an apparatus that includes a chamber rotor with a chamber and an extension rotor with an extension. The rotors are housed in a rotor case. A pressure cavity is at least transiently formed by the extension rotor and the chamber rotor. The present invention also includes a compressor that includes a chamber rotor with a chamber and an extension rotor with an extension where the extension is adapted to be received in the chamber when the rotors are synchronously rotated. The compressor also includes a power input shaft attached to the extension rotor and a gear assembly attached to the rotors that is adapted to insure the synchronous rotation of the rotors. A rotor case houses the rotors and has an intake port and an exhaust port. The present invention also includes an engine that is similar to the compressor and includes a spark plug. Methods of compressing, pumping and generating electricity and mechanical power are also part of the present invention. | 06-09-2011 |
20110135526 | ROTARY COMPRESSOR - A rotary compressor is provided. A suction hole is formed through a middle plate of the compressor to distribute refrigerant into both upper and lower cylinders. Coupling bolts having an appropriate length couple the cylinders to the middle plate. The length of the coupling bolts may be defined such that deformation of vane slots of the cylinders due to coupling of the cylinders may be minimized or eliminated, and friction loss and leakage loss between the vane and the vane slot may be reduced, thus improving compressor function. | 06-09-2011 |
