| A gear pump has a toothed driving wheel, a toothed driven wheel, a front flange from which a projecting portion of the shaft protrudes, being connected to the shaft of the driving wheel, a back lid fixed to the case, and an intermediate flange between the case and the front flange. The intermediate flange has first and second chambers connected by a connection duct to the inlet or outlet fluid duct of the pump. A compensating ring is mounted in the first chamber and inserted on the shaft of the driving wheel to compensate the axial forces of the driving wheel and transmit the motion on the shaft of the driving wheel. A piston is mounted in the second chamber in order to stop against one end of the shaft of the driven wheel, in such manner to compensate the axial forces imposed on the toothed driven wheel. | ||||||

| A multi-rotor internal combustion engine has a plurality of rotary internal combustion units axially distributed along an engine axis. Each unit has a rotor mounted on an eccentric portion of the shaft inside a housing. The housings of adjacent rotary internal combustion units have different angular positions about the engine axis so as to angularly offset the housing from adjacent housings, which may provide for a more uniform temperature distribution around the housings and may also or instead allow optimising of the balancing of pressure induced side loads on the shaft of the rotors. | ||||||
| 69 | COMPRESSOR WITH LOW FRICTION SEALING | US13885100 | 2011-12-28 | US20130236343A1 | 2013-09-12 | Niels Lennart Ohlsen |
| The invention relates to a compressor comprising a rotatable portion where the active volume is divided by transverse wings (4a-b) and a rotatable ring element (2) with its normal at an angle to the rotation axis of the transverse wings. In any of their embodiments the sealing wings are attached to sealing holder taps (16bd1-2, 16ac1-2) that pass through driving slits (11a1-2, 11b1-2). The driving slits extend essentially parallel to the rotation axis of the transverse wings. Steering and driving the sealing wings in this fashion using the driving slits, aligns the sealing wings against the transverse wings, restricting wear of the sealing wings and decreasing friction. In one embodiment the sealing holder taps are provided with sliders (17, 17a1-2, 17b1-2, 17c1-2, 17c1-2), guiding and further reducing wear of the sealing wings and decreasing friction, by means of guides (22a-d). The invention further relates to such a compressor with the means (7, 18, 19) for arranging the ring element with its normal at a changeable angle to the main rotation axis thereby changing the compression ratio. | ||||||

The first end wall has communication means (16-5, 16-6 and 16-7) for supplying compressed air from the compressed air supply chamber to the side of the first radial bearing closer to the rotor. | ||||||

| 74 | Rotary positive displacement machine with orbiting piston | US10529910 | 2003-10-01 | US07311077B2 | 2007-12-25 | Ronald William Driver |
| A casing has a circular cylindrical internal surface delimiting an operating chamber. An orbiting piston is mounted so as to orbit about a chamber axis which is the axis of the internal surface. The orbiting piston has a circular cylindrical external surface, a generatrix of the external surface being adjacent to the said internal surface, and a diametrically opposite generatrix spaced form the internal surface. A vane member has a tip face which faces the external surface of the orbiting piston and which has a length substantially equal to that of the orbiting piston. A linkage connects the vane member to the orbiting piston to keep the tip face adjacent the external surface. At least one of the external and internal surfaces has individual compliant strips distributed around the one surface, which run parallel to one another, and project above the one surface. | ||||||
