| 20080232991 | ROTARY FLUID MACHINE - A rotary fluid machine includes an eccentric rotary piston mechanism that is configured such that an annular piston is accommodated in an annular cylinder chamber of a cylinder to form an outer cylinder chamber and an inner cylinder chamber. The cylinder and the annular piston relatively execute eccentric rotary motion. Each of the outer and inner cylinder chambers is divided by a blade into a first chamber and a second chamber. The blade and the annular piston are mutually movably coupled together by a swinging bushing. The blade is provided, in its contact parts with the annular piston and the swinging bushing, with sliding surfaces in order to prevent the occurrence of seizure and wear of the blade and the annular piston and the occurrence of gas leakage between the first chamber and the second chamber during operation. | 09-25-2008 |
| 20080273999 | Machine for compressing gasses and refrigerant vapors - A machine for compressing gases and vapors includes a housing base containing an internal raceway, a spinning rotor containing a plurality of hollow cylinders, a plurality of spherical balls serving as positive displacement pistons which roll atop a housing base raceway and which reciprocate within the rotor cylinders, a static center rod containing intake and exhaust ports and a plurality of magnets providing rotational torque to the rotor, which are driven by an AC or DC motor during operation. A preferred embodiment includes the step(s) of gas or vapor intake, compression and exhaust within each rotor cylinder through a cycle during which the ball pistons reciprocate into and out of each cylinder while rolling atop the housing raceway. A preferred embodiment includes compression of gas and vapor occurring quietly, efficiently, with low mechanical vibration and in any physical orientation of the machine. | 11-06-2008 |
| 20100196185 | ENCLOSED COMPRESSOR - An enclosed compressor includes a compression element configured to compress a working fluid, a casing and a fixing member. The casing has a substantially cylindrical shell plate and houses the compression element. The fixing member is welded to the shell plate. The compression element is fixed to the fixing member, wherein fixing of the compression by at least six fastening bolts. | 08-05-2010 |
| 20120195782 | SYSTEM FOR CONSTRUCTION OF COMPRESSORS AND ROTARY ENGINE, WITH VOLUMETRIC DISPLACEMENT AND COMPRESSION RATE DYNAMICALLY VARIABLE - A system for the construction of compressors and rotary engines having two rotors with one, or more displacers per rotor to create between the displacers two or more chambers. The chambers vary in volume according to the degree of separation between the piston caused by the varying and alternatively opposite velocities between the two rotors. This speed variation can be produced a length variation of the radius in which a regular and uniform rotary motion is transmitted or received transforming it into an oscillating motion. The distance between the displacers is modified by placing the drive mechanism on the slide rails and moving it by a spindle, a hydraulic piston or geared system. The other dynamically modifies the beginning of the suction and compression phases preventing sealing of the displacers in certain segments of the suction-compression chamber, to create an opening, allowing passage of fluids and preventing its displacement. | 08-02-2012 |
| 20140348683 | SEALING SYSTEM FOR GEROTOR APPARATUS - According to one embodiment of the invention, a gerotor apparatus includes a first gerotor, a second gerotor, and a synchronizing system operable to synchronize a rotation of the first gerotor with a rotation of the second gerotor. The synchronizing system includes a cam plate coupled to the first gerotor, wherein the cam plate includes a plurality of cams, and an alignment plate coupled to the second gerotor. The alignment plate includes at least one alignment member, wherein the plurality of cams and the at least one alignment member interact to synchronize a rotation of the first gerotor with a rotation of the second gerotor. | 11-27-2014 |
| 20160138590 | GEROTOR APPARATUS HAVING OUTER GEROTOR WITH STRENGHTHENING MEMBERS - According to one embodiment of the invention, a gerotor apparatus includes a first gerotor, a second gerotor, and a synchronizing system operable to synchronize a rotation of the first gerotor with a rotation of the second gerotor. The synchronizing system includes a cam plate coupled to the first gerotor, wherein the cam plate includes a plurality of cams, and an alignment plate coupled to the second gerotor. The alignment plate includes at least one alignment member, wherein the plurality of cams and the at least one alignment member interact to synchronize a rotation of the first gerotor with a rotation of the second gerotor. | 05-19-2016 |
