A flow control valve includes a valve body having a first section and a second section attached to the first section. A flow control member is positioned within the valve body and a shaft extends through the valve body and is connected to the flow control member to move the flow control member between an open position and a closed position. A sealing gasket is positioned within the valve body and engages the valve body to prevent the flow of fluid between the first section and the second section. The sealing gasket has an annular metallic body having an inner surface and an opposing outer surface, the outer surface defining a primary sealing surface, a groove formed in the outer surface, and an insert positioned within the groove, the insert defining a secondary sealing surface.

A sealing arrangement is provided for sealing a mounting groove formed in a first or second mounting member separated by a gap and defining a hydraulic passage. A gasket is mounted in the groove between the passage and gap. The gasket includes an annular gasket body having first and second axial ends and a buried reinforcement ring. The gasket body includes a unitary flange extending radially outward from the first axial end. The flange includes a first seal lip extending axially outward from the flange proximate the passage or gap. The first seal lip contacts a surface of the first or second mounting member facing the passage. The gasket body includes a second seal lip extending outward from the second axial end to contact a bottom surface of the mounting groove.

A sealed component assembly within an aircraft, comprising first 10 and second 12 components each facing surfaces, and a sealing member 20 extending between the facing surfaces. The sealing member includes a conductive portion 22 sandwiched between first 24 and second 26 sealing portions. The sealing portions extend between and in contact with the facing surfaces, and are made of a sealing material. The conductive portion is in contact with conductive regions of the facing surfaces and defines an electrical connection therebetween. The conductive portion is more conductive than the sealing portions. In a particular embodiment, the components are a floor panel and a floor beam. A sealing member 20 for a connection between two aircraft components is also discussed.

A gasket for preventing the separation of a pipe joint formed between plastic pipes such as pipes manufactured from PVC. The invention provides an internally restrained pipe joint including a bell with a substantially V-shaped annular groove. The annular groove includes a front radial wall and a rear radial wall and a gasket seated in the annular groove. The gasket includes an inner radial face, an opening defined by the inner radial face and an outer radial face with a front radial section located adjacent to the front radial wall of the annular groove and a rear radial section located adjacent to the rear radial wall of the annular groove. A plurality of toothed, rigid restraining segments is at least partially embedded in the gasket.

An O-ring seal system for pipe flanges having a backing ring, an O-ring seal positioned within the backing ring, and a vacuum ring positioned within the O-ring seal. The backing ring and the vacuum ring form a rigid base against which mating flanges on pipes can be bolted together, thereby preventing bending of the mating flanges and permitting flange bolts to be torqued to their full tensile load limit without damage to the mating flanges. The O-ring seal system is constructed so that the O-ring seal is retained between the mating flanges without the need to position the O-ring seal in a groove in one of the mating flanges. Bending of the flanges is minimized since the flanges are clamped against the backing ring, minimizing stresses due to bending, thereby extending the service life of the flanges.

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.

An object is to provide a metal gasket that can form a wide contact width for a counterpart sealing face and that can achieve excellent sealing properties even when a blow hole is generated in the counterpart sealing face, and the object is achieved by a metal gasket having a bead portion to be in contact with a counterpart sealing face to form a sealing portion, formed on a gasket main body. The bead portion includes an arc portion that is convex toward the counterpart sealing face and hem-rising portions that each obliquely rise from the gasket main body toward the arc portion, on both hems of the arc portion. A connection portion between the arc portion and the hem-rising portion is formed to be convex toward a convex side of the bead portion. Plastic distortion for an overall width of the arc portion is lower than that of the connection portion. A contact pressure distribution in the arc portion in a compression state has a shape that is flat and wide in a width direction of the arc portion.

A system, in certain embodiments has, a fluid seal having a seal body, including a seal interface having one or more engagement portions, a first elastomer portion disposed along the seal interface, and a second elastomer portion disposed along the seal interface, wherein the first and second elastomers have material properties that are different from one another.

The present invention relates to a control plate as it is for instance used in pneumatic or hydraulic controls. An example of such a control plate is a transmission control plate with which automatic transmissions are controlled hydraulically.
