82 Piston Valve Internal Combustion Engine US12100420 2008-04-10 US20090255507A1 2009-10-15 Craig Louis Althen
An internal combustion engine of two perpendicular, toroidal cylinders intersecting at two junctions with each cylinder containing one piston filling half of its volume. The pistons are 180 degrees out of phase; each alternately occluding one intersection or the other. Each piston completes a full power, exhaust, intake, and compression stroke in one revolution. Endplates of 45 degrees allow the combustion chamber junction to be permanently filled and sealed at all times; first by one piston, then by the tips of both pistons as the complementary-angled endplates tangentially slide past one another, and then by the other piston. Compressed gases are shunted into the crossing cylinder's combustion chamber. Both pistons orbit continuously, one-way. Airflow is also one-way. Each piston is mounted to a sealed, 360-degree, counterbalanced ring gear. One ring gear is positioned centrally and the other peripherally to prevent interference. These maintain coordination between the pistons and provide output.

90 Turbostatic compressor, pump, turbine and hydraulic motor and method of its operation US10977664 2004-10-28 US20050260092A1 2005-11-24 Stephen Bolger
A variable-volume positive-displacement device configured to accommodate large flow volumes is disclosed. The variable-volume positive-displacement device despite being compact and lightweight, maintains pressure ratios of over 10 to 1 in a single stage operation. There is little loss of working fluid leakage, due to optimum sealing configurations and extremely low-seal sliding speeds. The device comprises a housing defining a closed chamber within opposing walls and a displacer mounted within the housing. The displacer maintains sliding contact with each of the inner wall surfaces of the chamber as it orbits and engages each of the inner wall surfaces in sequence. The volumes of the chambers surrounding the displacer vary as the displacer moves, depending on the position of the displacer. Working fluid is introduced into the chamber via inlet ports or is discharged via an outlet. This device may be used to replace conventional piston pumps, rotary pumps, scroll pumps, screw pumps, roots blowers, gear pumps and wankel displacers for pumping gases and liquids in applications requiring reduced frictional losses and tight sealing and relatively large displacement in a small volume. With integral valve-operators, the inventive device replaces turbines used for expansion of gases with large pressure ratios. This invention is particularly useful for constructing Brayton cycle engines and refrigerators. The inventive device offers improved operation and functional characteristics and lower cost of manufacture.

93 Two-stage rotary vane motor US139184 1998-08-25 US6086347A 2000-07-11 Antonin Ryska; Jiri Ota; Herman H. Viegas; Bruce E. McClellan
A two-stage rotary vane motor is provided that is particularly efficient for use in cryogenic refrigeration systems where the mass flow rate of the drive fluid (which may be expanding cryogen gas) varies substantially. The two-stage rotary vane motor includes a housing enclosure having first and second fluid chambers, each with their own inlets for receiving pressurized cryogen, and first and second rotors rotatably mounted within the chambers by means of a shaft assembly having an output end. In operation, when the mass flow of the drive fluid is high (350 pounds per hour), fluid is admitted through the inlets of both the chambers of the housing enclosure to drive both of the rotors. However, when the mass flow of the drive fluid drops to a low level (i.e., 100 pounds per hour), expanding cryogen is admitted only through the second chamber of the housing enclosure to drive only the second rotor. An overrunning clutch may be used to engage and disengage the first rotor from the shaft assembly in coordination with the admission of drive fluid through both or only one of the housing inlets.

97 Scroll type fluid displacement apparatus with balanced drive means US244961 1981-03-18 US4824346A 1989-04-25 Masaharu Hiraga; Kiyoshi Terauchi; Kiyosh Miyazawa; Seiichi Sakamoto
A scroll-type fluid displacement apparatus, in particular, a compressor unit is disclosed. The unit includes a housing with a fluid inlet port and a fluid outlet port. A fixed scroll with first end plate and first spiral element is fixedly disposed in the housing. An orbiting scroll with a second end plate and a second spiral element is disposed for orbiting motion in the housing. The first and second spiral elements interfit with one another at an angular offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. A drive pin extends from an inner end of a drive shaft. The orbiting scroll has a boss which rotatably supports a bushing. An eccentric hole is formed in the bushing and the drive pin is received within this hole. The center of the drive pin is located on an opposite side to the center of the drive shaft with regard to a straight line, which passes through the center of the bushing and is perpendicular to a connecting line passing through the center of the drive shaft and the center of the bushing. The center of the drive pin also is beyond the connecting line in the direction of rotation of the drive shaft. The bushing has a balance weight for cancelling a centrifugal force which arises because of the orbiting motion of the scroll member and bushing. Dynamic balance is accomplished by the use of a pair of balance weights affixed to the drive shaft for generating a moment of the same amount, but opposite in direction, to the moment generated by a force due to the interaction of the centrifugal force of the orbiting parts and the first balance weight.
98 Rolling cylinder engine system US137959 1987-12-23 US4776777A 1988-10-11 George D. Doty

100 Method of manufacturing a rotor US812610 1985-12-23 US4680844A 1987-07-21 James W. Rupp
A method of manufacturing a rotor (70) for use in an air motor. A shaft (10) is machined to have bearing surfaces (16 and 18) and adjacent ends (12 and 14), respectively. A working surface (20) with helix grooves (22, 24 and 26) is machined into the shaft (10). A locking surface (34) is machined into the shaft between the working surface (20) and end (14). A ring (36) is machined with helix grooves (38, 40 and 42) on its periphery and an inner diameter (44). The inner diameter has a diameter less than the locking surface (34) but greater than the bearing surface (18). The ring (36) is placed on bearing surface (18) of shaft (10). The shaft (10) with ring (36) on bearing surface (18) is placed in a fixture (50) and a tension force is applied to ends (12) and 14 ). The tension force causes the shaft (10) to axially expand and radially contract. When the diameter of the locking surface (34) is approximately equal to the diameter (44) of the ring (36), the ring (36) is pushed into contact with the working surface (20). After the helix grooves (22, 24, 26) are aligned with helix grooves (38, 40 and 42), the tension force is released allowing the locking surface to expand and frictionally hold the shaft (10) and ring (36) together such that a herringbone pattern is formed for rotor (70).
