Abstract: A valve assembly for a turbine engine includes a valve arranged in an air flow path.
The valve has a shaft. The valve is movable between an open position and a closed position. A hydraulic actuator is coupled to the shaft. The hydraulic actuator is configured to utilize fuel as a working fluid. The hydraulic actuator is configured to move the valve between the open position and the closed position.-

Abstract: A valve member is mounted on a shaft to pivot within a fluid passage. A control selectively moves a piston in a linear direction to control a position of the valve member in the fluid passage. The piston causes a roller pin to move as the piston moves linearly. The roller pin is mounted in crank collars of a crank shaft such that movement of the roller pin causes the crank collars to rotate crank shaft rotating position, and the valve shaft. The roller pin is mounted within the crank collars by bearings. The bearings each have an outer race associated with a crank collar, an inner race associated with the roller pin, and bearing members separate the inner and outer race. There is a spring bias resisting movement of the inner races relative to said roller pin. An anti-ice system is also disclosed.

Abstract: A bleed valve includes a housing with an inlet coupled to an outlet by a duct, a guide tube with an orifice fixed in the housing between the inlet and the outlet, a piston, and baffle. The piston is slideably supported on the guide tube and is movable between an open and a closed position, the duct fluidly coupling the inlet and outlet in the open position, the duct fluidly separating the inlet and outlet in the closed position. The orifice fluidly couples the inlet and outlet in the open and closed positions to move piston between the open and closed positions according to differential pressure between the bleed valve inlet and outlet. The baffle is slideably supported by the guide tube to set the differential pressure at which the piston moves between the open and closed positions. Gas turbines and differential pressure adjustment methods are also described.

Abstract: A piston ring assembly includes an inner ring, a first outer ring, and a second outer ring. The inner ring has an outer surface and an inner surface that extends between a first inner ring face and a second inner ring face. The first outer ring has a first outer ring outer surface disposed opposite a first outer ring inner surface, each extends between a first outer ring face and a first outer ring second face. The first outer ring inner surface engages the outer surface. The second outer ring has a second outer ring outer surface disposed opposite a second outer ring inner surface, each extends between a second outer ring first face and a second outer ring second face.

Abstract: A ball shaft for a coolant valve includes a body extending from a first end to a second end through an intermediate portion defining an axis of rotation, and a ball section formed on the intermediate portion. The ball section includes an outer surface, an inner surface that forms a coolant receptacle, and a slotted opening extending from the outer surface to the inner surface. The slotted opening includes a width of between about 0.0374″ (0.9499 mm) and about 0.0364″ (0.9246 mm).

Abstract: A pressure actuated switching valve includes a first valve chamber including a first chamber portion. The first chamber portion has a first inner diameter, a second chamber portion having a second inner diameter that is greater than the first inner diameter, a third chamber portion having a third inner diameter that is greater than the first inner diameter, a fourth chamber portion having a fourth inner diameter that is greater than first inner diameter, and a valve member. The valve member includes a first section having a first outer diameter that is greater than the first inner diameter. A second section of the valve member has a second outer diameter that is closely matched to the third inner diameter. A third section of the valve member is arranged has a third outer diameter that is greater than the first outer diameter.
