摘要： A compressor casing defines an air inlet port, an air intake passage with an impeller accommodated therein, a diffuser and a scroll all communicated with each other in the order named. An annually extending chamber is formed between the passage and the scroll and has an opening opened sideways of the impeller in the passage, enhancing an ability of discharging a surging-occuring range to a lower flow rage. The compressor casing may be divided into a casing main body and an inner casing so as to decrease fabrication cost of the compressor casing.

摘要： Nozzle shafts and a nozzle drive mechanism are disposed on the side of a bearing casing and a compressor whose temperatures are lower than that of a turbine, and elements slidable in the radial direction of the turbine wheel are eliminated from the nozzle drive mechanism so that any adverse effects due to oxidization at high temperatures and slide wear can be eliminated. Thus durability and reliability of the device can be improved.

摘要： An arrangement for attenuating vibrations of blades attached to a peripheral surface of a rotor of an axial turbine. A through hole is formed in each rotor blade in a generally thickness direction of the blade so that the through holes in combination define a single annular passage near a rotor surface when all of the rotor blades are attached to the rotor. A wire is provided to extend through the aligned through holes. Thus, the wire frictionally contacts the through holes when the blades are caused to vibrate due to a gas pressure and a centrifugal force generated upon operation of the axial turbine. Friction contact between the wire and the through holes attenuates vibrations of the blades.

摘要： A supercharger thrust bearing for use in a machine rotatable at a high speed includes radial oil grooves formed in a pad surface. Gradients are formed at the outward radial ends of the oil supply grooves such that the groove depth sequentially diminishes as the outside in the radial direction is approached. The machine rotatable at a high speed is, for example, a boat or a ship. The lubricating oil inside the oil supply grooves is forced out by the gradients and creates a dam. The lubrication oil flowing in a circumferential direction on the pad surface, which is heated on the pad surface, is stopped by this dam and turned to a radially outward direction. The heated oil is pushed out from the pad surface and the new cold oil is caused to flow onto the pad surface from the radial grooves.
