Abstract: Flexible seal assemblies having a relatively low torsional rigidity and high longitudinal flexure to thereby allow the flexible seal assembly to flex between adjacent components and maintain a seal, even when movement between adjacent components occurs, is described. In some embodiments, the flexible seal assembly includes one or more layers of metal matrix material, the metal matrix material being comprised of a plurality of short segments of thin wire arranged randomly and sintered together to form a semi-rigid sheet. The one or more layers of metal matrix material can be sandwiched between an upper casing and a lower casing of a metal alloy casing. In various embodiments, additional features are provided for helping to make sure the seal assembly stays together, such as spot welds formed through the seal assembly, an S-shaped casing, and a recess/protrusion feature provided on adjacent layers of metal matrix material.

Abstract: A one-way valve is provided. The valve provides a housing with a through hole having an upstream portion and a downstream portion. The upstream portion has a reduced diameter compared to the downstream portion. The housing contains a valve seat. A valve member, or poppet, moves within the through hole from a valve closed position and a valve open position. A low pressure facing side of the poppet engages an elastic member of a compression member that biases the poppet in the valve closed position. A high pressure facing side of the poppet engages a resilient metal seal in the form of an annular disc, which may have a generally wavy or undulating shape. The outer ends of the resilient metal seal are curved to releasably engages the valve seat.

Abstract: A one-way valve is provided. The one-way valve may be, for example, a check valve, a relief valve, or the like, which may be in the form of a poppet valve. The valve provides a housing with a through hole. The through hole has an upstream portion and a downstream portion. The upstream portion has a reduced diameter compared to the downstream portion. The housing contains a valve seat, which typically has a taper. A poppet, or valve member, moves within the through hole from a valve closed position and a valve open position. The poppet has a high pressure facing side and a low pressure facing side opposite the high pressure facing side. The low pressure facing side of the poppet engages an elastic member of a compression member that biases the poppet in the valve closed position. The high pressure facing side of the poppet engages a resilient metal seal in the form of an annular disc. The annular disc has a generally wavy or undulating shape.

Abstract: The technology of the present application provides an apparatus for sealing and filtering. The apparatus includes a sealing component and a filtering component. The sealing component has an annular structure and a first connecting component. The annular structure includes a sidewall defining a recess. The first connecting component extends from the annular structure in a first direction. The filtering component has a filtering material and a second connecting component. The filtering material has a flat structure. The filter material is configured to filter fluid passing therein in a second direction. The sealing component and the filtering component are coupled by the first connecting component and the second connecting component.

Abstract: The technology of the present application provides a floating ball valve. The ball valve includes a valve body having a recess or chamber and a ball contained in the recess. A valve seat forms a sealing relationship between the ball and the fluid conduit. The valve seat has a resilient seat or member formed on the valve seat that confronts a surface of the ball. An energized spring seal on the opposite side forms a seal between the valve body and the valve seat and pushes the resilient seat towards the ball.

Abstract: A head gasket assembly comprising a gasket body comprising a plurality of layers of gasket material a combustion aperture extending through said gasket body, the aperture defined by an inner periphery of the gasket, said periphery adapted to be fitted with a resilient seal element, and a resilient seal element disposed about the inner periphery of the aperture in the gasket body, said seal element being formed of a helically-wound metal wire or metal tube seal at least partially surrounded by a jacket having a flange protruding therefrom and engaging the gasket body.

Abstract: A head gasket assembly is provided comprising a solid non-compressible or rigid gasket body comprising a plurality of apertures for engine coolant, oil and combustion chambers. The gasket body has grooves formed therein for retaining and controlling the compression of elastomeric seals used for sealing engine coolant and oil apertures. The gasket body is then fitted or accompanied by a combustion seal. The combustion seals are specifically designed for the particular engine application, based on temperature, pressure and other operating characteristics. This assembly allows a direct fit with standard engine technology and requires no machining of heads, blocks, or cylinder liners. The result is a gasket body that precisely controls the compression on the seals, which improves engine performance without any machining of the engine while carrying highly elastic compounds to seal coolant and oil.
