摘要： In a silencer, holes are disposed in one row with intervals to each other along one direction, holes forming the one row are disposed in a plurality of rows in a direction perpendicular to the one direction, and positions of the holes in adjacent rows are shifted in the one direction and disposed in a zigzag pattern. A disposition interval of the holes of an outer edge hole row forming one row in at least two sides opposite to each other in the silencing porous plate is set to be larger than a disposition interval of the holes of a row inside the outer edge hole row.

摘要： A variable nozzle device includes: a first plate-shaped member having a first plate portion having an annular shape and being fixed to a bearing housing; a second plate-shaped member having a second plate portion which has an annular shape and which defines a nozzle flow passage between the first plate portion and the second plate portion, the second plate portion having a surface disposed so as to face the first plate portion and another surface disposed so as to face at least partially a scroll flow passage formed inside a turbine housing; at least one nozzle support having, with respect to an axial direction of the nozzle support, an end coupled to the first plate portion and another end coupled to the second plate portion; at least one nozzle vane rotatably supported between the first plate portion and the second plate portion; and a variable nozzle mechanism configured to change a vane angle of the at least one nozzle vane. The second plate portion is formed to have a larger thickness than the first plate portion.

摘要： In a disc axis adjusting mechanism in a gas turbine, the gas turbine has an exhaust gas diffuser provided between a casing wall and a bearing case which are connected to a downstream side of a turbine, a plurality of struts provided at intervals in a circumferential direction, and strut covers coupling an outer diffuser and an inner diffuser of the exhaust gas diffuser so as to cover the struts, and the mechanism comprises: a plurality of air introduction holes formed in the casing wall so as to allow the interior and exterior of the wall to communicate with each other; a sensor unit configured to detect a parameter corresponding to the thermal elongation of each of the struts; and a flow rate adjustor configured to adjust the flow rate of air flowing through each of the air introduction holes based on a detection value detected by the sensor unit.
