Locomotive diesel engine cylinder head cover assembly seal
A method, system and device for the sealing of a locomotive diesel engine cylinder head support frame's cover assembly. The method, system and device comprise a one-piece elastomeric seal having a plurality of protrusions/legs/appendices specifically constructed for sealing the top external covering of the individual power assemblies to prevent oil leakage during the operation of the diesel engine. The diesel engine's cylinder head cover seal has a combination of a dimensional profile and a material composition(s) that extends the diesel engine's cylinder head support frame cover seal's contact integrity and life.
Method of producing gasket and gasket
A method of producing a gasket in which burrs can be prevented from being formed, and a mold failure can be suppressed, and a gasket are provided. A method of producing a gasket includes: a step S1 of preparing a metal mesh member and expanded graphite; a step S2 of placing the metal mesh member around the expanded graphite in a manner that a long belt-like composite body in which the expanded graphite is enveloped by the metal mesh member is formed; a step S4 of adjusting the shapes of longitudinal end portions of the composite body in a manner that, in the short-side direction of the composite body, the width dimensions of the longitudinal end portions of the composite body are smaller than the width dimension of a longitudinal middle portion of the composite body; a step S5 of spirally winding the composite body in a manner that a tubular body in a multiply wound state in which an axial direction coincides with the short-side direction of the composite body is formed; and a step S6 of compress molding the tubular body in the axial direction of the tubular body.
INTERFACE BETWEEN AN OUTER END OF A WING AND A MOVEABLE WING TIP DEVICE
An aircraft (102) including a wing (101), having a fixed wing (105) with a wing tip device (103) moveably mounted at the outer end thereof. The wing tip device (103) is moveable between: a flight configuration; and a ground configuration. The wing tip device (103) and the fixed wing (105) are separated along an oblique primary cut plane (113). The wing tip device (103) and the fixed wing (105) meet along an interfacing cut line (135). The interfacing cut line (135) comprises a first length (137) offset from the primary cut plane (113) in a first direction; a second length (141) offset from the primary cut plane (113) in a second direction, opposite to the first direction; and a transition section (139) over which the interfacing cut line (135) transitions from the first length to the second length.
Supported elastomeric foams and processes for making same
A supported elastomeric foam (100) includes an elastomeric matrix (102) formed of an elastomer and including a reinforcement region (104) and a foamed region (106). The foamed region includes gas filled cells (108) in the elastomer, and the reinforcement region includes a porous layer (204) having an interconnected network of pores at least partially imbibed with the elastomer. The foam can include an adhesive at a surface of the foam. A compressible seal (802) including a compressible body, which can be elastomeric foam, can also include a pattern of discontinuous adhesive regions about which the compressible body can deform to form a sea. The supported elastomeric foam can form a gas tight seal in an interface when placed under minimal compression.
HOUSING FOR MOTOR VEHICLE-RELATED USES
A housing for motor vehicle-related uses, which comprises at least one housing wall and at least one first sealing element connected to the housing wall for orienting and guiding a second sealing element made of a different material by comparison with the first sealing element. According to the invention the first sealing element is designed as at least one arm which yields resiliently relative to the housing wall. The arm supports the second sealing element on its surface remote from the housing.
BIDIRECTIONAL PRESSURE-INTENSIFIED SEAL
A pressure-energized bidirectional seal having a main body having a first end and a second end and a pair of legs extending from the second end of the main body, the pair of legs having an inner surface and an outer surface, the inner surface forming a hollow interior opening in a first direction. The bidirectional seal includes at least one rib extending from the outer surfaces and configured to sealingly engage a mating surface of a mating body the at least one rib forming a sealing zone opening in a second direction opposite of the first direction.
Seal assembly including shape memory stiffening members
A seal assembly configured to seal against a surface of a seal depressor includes a body member configured to elastically deform in at least a first direction of motion from an original state into a compressed state in response to experiencing a load. The body member exerts a sealing pressure against the surface of the seal depressor when in the compressed state. The seal assembly also includes one or more shape memory stiffening members constructed from a shape memory material having a high energy state and a low energy state. The one or more shape memory stiffening members are oriented perpendicular to the first direction of motion of the seal assembly and configured to stiffen the body member of the seal assembly when the shape memory material is in the high energy state.
Seal system having silicon layer and barrier layer
A seal system includes a ceramic component, a metallic component, a silicon-containing layer, and a barrier layer. The ceramic component has a first surface region that defines a first surface roughness. The metallic component is situated adjacent to the first surface region and has a second surface region facing the first surface region. The silicon-containing layer is on the first surface region of the ceramic component and has a contact surface that defines a second surface roughness which is less than the first surface roughness. The barrier layer is on the metallic component and in contact with the silicon-containing layer and serves to limit interaction between silicon of the silicon-containing layer and the metallic component. The barrier layer includes at least one of alumina or MCrAlY.
