A seal assembly can include a sealing component and a spring energizer located within a seal cavity or spring cavity of the sealing component. The sealing component provides an exterior surface for providing protection of the seal cavity and spring energizer from an external or contaminated environment, such as the atmosphere. The sealing component can have two distinct first and second sealing points. Each distinct first sealing point can have two discrete first sealing points and each second sealing point can have two discrete second sealing points. Part of the spring energizer can extend externally of the sealing component.

The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within a conductive female housing and connector assembly. The seal spring compresses and provides adequate spring force against a disk ferrule assembly, pressing the disk ferrule assembly, with a wire shield, against a conductive female outer housing, providing a grounding scheme for the connector assembly. The seal spring also seals against the female outer housing and a wire.

A seal for sealing three adjacent structures is provided. The seal has a plurality of sealing legs designed to seal against different parts of the adjacent structures. In addition, the seal may have side sealing structures that seal against a groove in which the seal may be located.

A device for sealing a valve for controlling a coolant of an internal combustion engine of a motor vehicle is described, which valve is mounted in a cooling system together with a valve housing, wherein the valve housing contains, at the inlet and/or the outlet side, a sealing ring which has an annular wall and a spaced annular lip extending away from the annular wall from a contact point.

A tubular joint comprising first and second tubular members, an annular sealing element positioned between the tubular members and a clamping device for clamping the tubular members to each other with an end face of the first tubular member in contact with an end face of the second tubular member. The sealing element comprises an annular metallic body. Two sealing surfaces on the metallic body are designed to mate with tapered sealing surfaces on the tubular members. A first spring-energized polymeric seal member is mounted to the metallic body and configured to be in sealing contact with a radially extending sealing surface on the first tubular member. A second spring-energized polymeric seal member is mounted to the metallic body and configured to be in sealing contact with a radially extending sealing surface on the second tubular member. Seal members are prestressed upon clamping of the tubular members to each other.

A seal with a wedging element for adjustably compressing the seal. The seal abuts a surface, such as a gate of a gate valve, to seal against the surface with a sealing force that prevents fluid flow therebetween. The sealing force of the seal may be increasing or decreasing compression by adjusting the wedging mechanism. For example, as the seal wears away due to friction between the seal and a sliding gate, the compression may be increased in the wedging mechanism to increase the sealing force to a low threshold.

Exemplary embodiments of a high temperature aging cell provide a metal-to-metal fluid seal, and generally include a central tension post containing a flange having an inclined surface; and a seal ring concentrically arranged thereon, its outer circumference positioned at least partly intermediate the flange and the cell interior surface. In various embodiments, a thrust ring retains the seal ring; a thrust washer engages the thrust ring; a tension ring is attached to the tension post for biasing the thrust ring toward the flange; and an outer cap retains various components in relation to the aging cell. A pressure control device allows for pressure elevation. Exemplary embodiments of a sample aging method generally include aging a liquid sample by sealing the sample in the cell via biasing of the seal ring into sealing engagement with an interior surface of the cell. Subsequent sample treatment may involve elevating its temperature and/or pressure.

A raintight compression connector has a connector body with first and second portions and a bore extending therethrough for connection to a conduit. An upper sealing ring is dimensioned to contact the connector body to make sealing contact with a conduit. The upper sealing ring has first, second and third regions. The first region has a first sloping surface to contact a recess shoulder in the connector body and the third region has a third sloping surface to contact an inner surface of the connector body. Specific slopes for these sloping surfaces are disclosed. The upper sealing ring can also be used in a raintight compression coupler.

A sealing device for a hydraulic assembly wherein hydraulic fluid is contained in working chamber (53) formed between body (52) and thrust member (51) of the assembly. The device comprises annular seal (63) with opposed sealing faces which are urged into sealing engagement between body (52) and thrust member (51) which have convergent sealing faces. The device may also have a pressure relief valve (100) tapped into the over-stroke end of chamber (53) to protect seal (63) from over-stroke damage comprising porous body (101) which allows fluid to bleed from chamber (53) and allows seal (63) to pass the tapping point without obstruction.

A seal carrier for a ball valve includes a carrier body to be located between a ball and a portion of a valve body. The carrier body may have an annular channel for carrying a ring seal in a side to be located proximate the ball. A spring is located at a peripheral portion of the carrier body. An end portion of the spring is configured to abut against the portion of the valve body, and the spring is configured to provide a compressive force between the portion of the valve body and the ball in a direction parallel with the direction of fluid flow through the ball valve assembly. A ball valve assembly may include such seal carriers. Methods of forming such seal carriers are also included.
