Abstract: PROBLEM TO BE SOLVED: To improve the sealing effect of a seal, and to reduce the leakage by reducing the influence exerted by the deformation caused by an operating load upon a sealing member. SOLUTION: A liner 76 for the guide assembly track opening 56 for a gas turbine engine is provided with a pair of parallel curved rail walls 102, 104 and a plate 15 extended between these rail walls. This plate 15 is provided with a pair of flanges 158, 166 extended from the walls, and is engageable with the engine stator structure by means of these flanges. By forming the liner 76 by a material harder than the housing 42, the durability of the ring assembly for combining the liner 76 with the liner 76 can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly provided with stator vane trains to be repeatedly positioned after replacement and having an allowable level of durability and a replacing property. SOLUTION: A stator vane blank for forming a stator vane for a rotary machine includes a forged head part 84 having a pair of surfaces provided with an angle forming an outward surface 104, and these surfaces has an angle larger than the angle of a pair of surfaces facing to an air foil and provided with an angle forming an inward surface 106. The outward surface 104 is provided with about nine degree of angle α, and the inward surface 106 is provided with about three degree or less of angle β.

Abstract: PROBLEM TO BE SOLVED: To reduce leak by improving seal effect of a seal, and reducing effects of deformation generated by action load on a seal member. SOLUTION: This roller assembly 58 includes a pin 78 having a tightening surface 130 to transmit force from the roller assembly 58 to a support part 86, and a collar 84 of a separate structure engaged with the tightening surface 130, extended in an axial direction to the support part 86 to part the tightening surface 130 from the support part 86, and disposed around the pin 78. The collar 84 has a first range 140 to be engaged with a shaft part 128 by compression force, and a second range 141 diametrically outwardly separated from the first range 140 in a diametrically outward direction from the shaft part 128. By using this collar 84, fatigue life of the roller assembly 58 can be elongated, and durability of the pin 78 can be improved.

Abstract: PROBLEM TO BE SOLVED: To provide an adhering device to have durability and handling difficulty being low enough to be allowable. SOLUTION: A stator assembly contains a peripheral extending preformed lab strip 58. The lab strip is adhered to an inside shroud 56 by applying a bond (a registered trade mark) material 86, such as an adhesive and a primer, directly on a gap between the inside shroud 56 and the pre-formed lab strip 58. The inside shroud 56 is formed of a thermoplastic material and the lab strip 58 is formed of a preformed silicone rubber, and a primer of epoxy resin is provided such that relative operation with the thermoplastic material is effected. The pre-formed lab strip 58 is deformed radially inwardly during manufacture of an assembly and this constitution extends a bond material 86 in a vertical direction, i.e., the direction of the width of a blade, and a shearing strength on a contact surface is increased.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes repeatedly positionable after replacement, having an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises a plurality of vanes extending into an operating medium gas flow passage through a case extending in circumferential direction. In this case, the stator assembly comprises a surface 76 facing inward on a base part 48, and the inward facing surface 76 is connected, in the state of being installed, to a flat surface 74 corresponding to a non-flow passage surface of a casing at a position of each vane. In one embodiment, these surfaces are on the same plane.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes with an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises shrouds. The detail of various coinfigurations limiting the movement of stator vanes 28 into a flow path by the limitation of the shrouds is expanded. For example, a clip member 62 extends throiugh an opening part 64 located at a vane tip part 52 of the stator vane 28, and the clip member 62 is disposed on a non-flow path surface of an inside shround 56 so as to limit the vane tip part 52 of the stator vane 28 for an inward movement.
