A method for manufacturing a seal is disclosed. The method includes depositing one or more layers of a first material on a metal base plate of a second material to form a main seal body of the seal. The second material is different from the first material. The method further includes separating the seal from the metal base plate such that the seal includes the main seal body and an outer seal layer retained on the main seal body to form a seal face surface of the seal. The outer seal layer is formed of a portion of the metal base plate.

A stator seal for a turbine assembly includes a seal base securable to a turbine stator and including an annular inner surface, and an abradable coating disposed on the annular inner surface. The abradable coating and the annular inner surface have a predefined cross-sectional profile including a transient operation section that facilitates axial expansion and a steady state operation section that facilitates a tighter clearance.

A seal for a gas turbine engine includes a top, a bottom, a left side, a right side, a back and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side. The top includes a first vane mating surface and the bottom includes a second vane mating surface.

A static gasket configured for establishing a seal between a cylinder head and an engine block including at least one layer having an opening and at least one compression bead. The compression bead extends circumferentially about the opening and projects out of a plane for deforming elastically when the gasket is compressed between the cylinder head and the engine block. A compression limiter which is formed from a metal wire is disposed radially between the opening and the compression bead for preventing the compression bead from being fully flattened, even if the cylinder head is overloaded onto the engine block. The compression bead is preferably induction and/or resistance welded to at least one of the layer(s).

A method is provided for forming a gasket for sealing opposing flange surfaces of a pipe having corrosive fluid flowing therethrough. The method comprises defining a gasket profile incorporating a serrated profile core having a flange extending radially inward therefrom. A deformable pillow extends radially inward from the serrated profile core, to define a gasket intermediate portion about the flange, and a gasket inner portion radially inward from the flange. The deformable pillow material and thickness are selected such that upon compression to a thickness no less than the core thickness, the gasket inner portion exhibits a stress level sufficient to preclude corrosive liquid flowing through the pipe from passing radially outward beyond the gasket inner portion, and the gasket intermediate portion exhibits a stress level sufficient to preclude gas and liquid flowing through the pipe from passing radially outward beyond the gasket intermediate portion.

A method of forming a packing cartridge from a plurality of packing components comprising placing a plurality of individual packing components in a stacked manner in a die tool assembly and compressing the plurality of packing components in opposite directions to form the packing cartridge. The plurality of packing components forming the packing cartridge are mechanically linked together.

The invention relates to a brush seal, in particular for the sealing of gaps occurring in turbomachines, including a plurality of individual fibers, individual wires or bundles of individual fibers or wires, wherein, in each case, at least two individual fibers or wires, and/or at least two fiber bundles or wire bundles are braided or twisted into a fiber or wire package. In addition, the invention relates to a method for producing a brush seal.

The method includes providing a generally annular sealing element, the sealing element having an inner circumferential sealing surface configured to engage with a relatively movable member, and an outer casing blank including one of: a generally axially-extending section and a generally radially-extending section extending inwardly from the axially-extending section; and a generally annular disk and a generally cylindrical tube. The method may also include determining a desired diameter for a generally annular outer casing, removing a portion of the provided one of the radially-extending section and the annular disk, such that a diameter of the outer casing blank is about equal to the desired diameter, and coupling the sealing element to the outer casing blank after removing the portion of the provided one of the radially-extending section and the disk.

A sealing assembly for establishing a gas and fluid tight seal in an internal combustion engine is provided. The sealing assembly includes a plate of metal which has a plurality of openings and at least one generally flat surface. The plate also has at least one shelf which circumferentially surrounds one of the openings and which opens to the generally flat surface and the opening. The sealing assembly further includes at least one sealing bead of an elastically compressible material which is engaged with the shelf and extends outwardly therefrom past the generally flat surface for sealing the plate with another component in the internal combustion engine.

The invention features a seal assembly for a high pressure liquid system. The seal assembly includes a seal carrier having a base portion defining a proximal end, a distal end, and a bore. The seal carrier also includes a seal disposed within the bore of the seal carrier. The seal carrier also includes a backup ring disposed within the bore of the seal carrier. The seal carrier also includes a hoop ring disposed substantially between the seal and the backup ring, the hoop ring having a proximal surface and an outer surface.
