摘要： A compound engine assembly with an engine core including at least one internal combustion engine, a compressor, and a turbine section where the turbine shaft is configured to compound power with the engine shaft. The turbine section may include a first stage turbine and a second stage turbine. The turbine shaft is rotationally supported by a plurality of bearings all located on a same side of the compressor rotor(s) and all located on a same side of the turbine rotor(s), for example all located between the compressor rotor(s) and the turbine rotor(s), such that the compressor rotor(s) and the turbine rotor(s) are cantilevered. A method of driving a rotatable load of an aircraft is also discussed.

摘要： An expander-compressor unit (10) includes a two-stage rotary expansion mechanism (3) having a first cylinder (41) and a second cylinder (42). In the expansion mechanism (3), a suction port (71) facing a working chamber on the upstream side in the first cylinder (41) and a discharge port facing a working chamber on the downstream side in the second cylinder (42) are formed. An intermediate plate (43) is provided between the first cylinder (41) and the second cylinder (42). In the intermediate plate (43), a communication passage (43a) for allowing communication between a working chamber on the downstream side in the first cylinder (41) and a working chamber on the upstream side in the second cylinder (42) is formed. The communication passage (43a) does not communicate with the working chamber in the first cylinder (41) during the suction process, and communicates with the downstream working chamber in the first cylinder (41) at or after the end of the suction process.

摘要： An exhaust heat energy recovery apparatus for an internal combustion engine that efficiently recovers exhaust heat energy without increasing engine exhaust back pressure, and a Brayton cycle apparatus applicable to the exhaust heat energy recovery apparatus. A Brayton cycle apparatus 1 using a scroll compressor 4 and a scroll expander 6 has a simplified and downsized structure. A working fluid is compressed inside a scroll compressor 4 and expanded inside a scroll expander 6 in spaces partitioned and sealed by combinations of fixed scrolls and orbital scrolls. The conversion efficiency from heat energy to kinetic energy is high. Heat is transferred from the exhaust to the working fluid through a pipe wall of a flow passage 30a and an expander case 12 of the scroll expander 6. This further downsizes the Brayton cycle apparatus 1. The back pressure of the energy source including the exhaust is unaffected.

摘要： A hub adapted to support an electromagnetic clutch and a hydraulic pump thereon is disclosed. The hub is generally hollow and cylindrical in shape, including a first annular mounting portion having an inner cylindrical mounting surface. The inner cylindrical mounting surface is sized to receive and precisely position therein a cylindrical flange of the hydraulic pump. The hub also includes an enlarged cylindrical flange portion disposed adjacent to the first mounting portion. A plurality of apertures are formed through the flange portion for securing it to an external mounting bracket. The hub further includes a second annular mounting portion having an outer cylindrical mounting surface. The outer cylindrical mounting surface is sized to receive and precisely position thereon a bearing assembly of the electromagnetic clutch. Thus, the hub provides precise co-axial mounting surfaces for both the hydraulic pump and the electromagnetic clutch. By mounting the hydraulic pump and the electromagnetic clutch in this manner, the rotational axes of the components thereof are precisely maintained co-axial during use.

摘要： Scroll fluid machine (1) in which the dislodgement of a slide bush (56) and a spring (61), which are provided in an eccentric bush (36), is prevented. Provided in receiving hole (58) of eccentric bush (36) are slide bush (56), which is movable in the direction of eccentricity, and spring (61), which biases slide bush (56) in a moving direction. A spring holding section (56b) and engagement projections (56a) are formed on slide bush (56). After slide bush (56) is placed in the receiving hole (58), engagement projections (56a) engage with eccentric bush (36) in a state in which slide bush (56) has been moved by the biasing force of spring (61), thus preventing slide bush (56) from falling off the receiving hole (58), and the spring holding section (56b) prevents the spring (61) from falling off the receiving hole (58).
