| PROBLEM TO BE SOLVED: To improve the accuracy of a rotor, to improve durability, to improve thermal efficiency and to reduce the cost in rotary fluid machinery. SOLUTION: This rotary fluid machinery is provided with a reciprocating piston 37 engaged with a cylinder 33 provided on the rotor 27, and a reciprocating vane 44 engaged with a vane groove 43 provided in the rotor 27. In the machinery, the rotor 27 is formed by a rotor core 31 supported on a rotating shaft 21 for storing the cylinder 33, and twelve rotor segments 32 divided in the circumferential direction to surround the periphery of the rotor core 31, and the vane groove 43 is formed between the adjacent rotor segments 32. By this arrangement, the dimensional accuracy of the vane groove 43 can be heightened without special precise machining, and heat conduction from the relatively higher temperature rotor core 31 to the relatively lower temperature rotor segment 32 is intercepted to restrain radiation of heat to the outside of the rotor 27 so that thermal efficiency can be heightened, and besides thermal deformation of each part of the rotor 27 can be lessened.

| 52 | Turbo compound arc piston engine | JP17422196 | 1996-06-13 | JPH09112289A | 1997-04-28 | BEN SOUFUKU |
| PROBLEM TO BE SOLVED: To improve heat efficiency by applying the constitution that an air-fuel mixture is sucked into an annular cylinder for compression with an arc piston, and fuel gases of high temperature and high pressure resulting from the ignition and combustion of the compressed air-fuel mixture are made to act on the head of the arc piston for causing the curved reciprocating motion of the arc piston within the annular cylinder. SOLUTION: When the left head of an arc piston 7 reciprocating along a curve begins an air compression stroke, the right head of the piston 7 enters an air intake stroke. As a result, an air intake valve 25 automatically opens and, then, a valve 2' for a scavenging port drilled in a division 3 automatically closes. In addition, when the head of the arc piston 7 compresses the air up to the top dead center of a combustion chamber 4, a fuel injection pump 23 and an ignition plug 24 operate to explode and burn an air-fuel mixture. Then, combustion gases of high temperature and high pressure generated due to the combustion of the mixture act on the head of the arc piston 7 to start a working stroke. When the arc piston 7 capable of performing the working stroke arrives at the bottom dead center, an extremely short exhaust pipe 16 opens, and the combustion gases are blown from the pipe 16 to the impeller 26 of a radical gas turbine 15 directly. | ||||||

| A rotary type expander is provided with two rotary mechanism parts which differ from each other in displacement volume. The outflow side of the first rotary mechanism part of small displacement volume is fluidly connected to the inflow side of the second rotary mechanism part of large displacement volume. The processes by which the volume of a first low-pressure chamber in the first rotary mechanism part decreases and the volume of a second high-pressure chamber in the second rotary mechanism part increases are respectively in sync. Refrigerant at high pressure is first introduced into a first high-pressure chamber of the first rotary mechanism part. Thereafter, this high-pressure refrigerant passes through a communicating passage and then flows by way of the first low-pressure chamber into the second high-pressure chamber while expanding. The after-expansion refrigerant flows out to an outflow port from a second low-pressure chamber of the second rotary mechanism part. | ||||||
