A valve assembly for use with a container such as a fuel tank. Embodiments of the assembly include an inlet and outlet provided on separate sides of the central axis of a housing, the housing being connected to a central conduit located in a container. The valve assembly includes inlet and outlet valves which allow the venting of air during filling and the intake of air as fuel is consumed. The valve assembly is arranged so that air flows through a less torturous path compared to known prior art, enabling a high rate of filling to be achieved.

The invention relates to a valve assembly (100) for a multi-scroll turbine (10) for controlling an overflow of exhaust gases between a first spiral (36) and a second spiral (38) and for controlling a bypass opening (50). The valve assembly 100 comprises a lever (110) and a valve closing element (120) which is operatively connected to the lever (110). Furthermore, the valve assembly (100) comprises a spring element (130) which is designed to pre-bias the valve closing element (120) the against lever (110).

In a double eccentric valve, a valve seat or valve body includes a rubber seal part in which a seat surface or seal surface is formed. An interference between the valve seat and the valve body is made minimum at a position of a rotary-shaft-directional end of the valve body in the radial direction of the valve body which is parallel to an extending direction of the axis of a rotary shaft.

A valve for a bypass conduit is comprised of a rigid inner frame having an arm with a tab at one end and a hinge at an opposite end. A flexible outer seal is positioned over the inner frame, the flexible outer seal defining a peripheral edge to substantially house the tab and arm of the inner frame. The valve is pivotable from a first position to a second position on the bypass conduit.

The present disclosure provides a valve for a respiratory bypass conduit, the valve further comprised of an inner frame that provides rigidity to a flexible outer seal. The inner frame has guiding flanges to guide the valve within he conduit, and a hinge portion to be secured within a slot of the conduit. Together, the hinge and the guiding flanged help the valve move from a first position to a second position. The present disclosure also provides for a method of assembling the valve for respiratory bypass conduit, whereby the inner frame is aligned with and inserted into the outer seal until a peripheral gap of the outer seal substantially houses the inner frame and an inner periphery of the inner frame surrounds a recessed portion of the outer seal to secure the outer seal in the correct orientation relative to the inner frame.

A unibody valve comprising a valve body including a first end and a second end spaced apart along a longitudinal axis, a central portion disposed between the first end and the second end, wherein the first end and the second end define a first flow passageway and a second flow passageway, respectively, and wherein the central portion defines an interior chamber, and a disc disposed within the interior chamber, wherein the interior chamber includes an enlarged side portion positioned outside of the at least one of the first flow passageway and the second flow passageway projected along the longitudinal axis, wherein the disc is disposed in the enlarged side portion when in an open position.

A valve comprising a valve body including a first end and a second end spaced apart along a longitudinal axis, a central portion disposed between the first end and the second end, wherein the first end and the second end define a first flow passageway and a second flow passageway, respectively, and wherein the central portion defines an interior chamber, a stem rotatably supported by the valve body about a rotation axis, wherein the stem includes a polygonal end, and a disc disposed within the interior chamber and including a polygonal aperture to receive the polygonal end of the stem.

A valve arrangement for a switching valve and to a switching valve for regulating a mass flow in a refrigerating circuit or a heating circuit, including a valve housing, which includes a feed opening and a discharge opening, including a valve piston, which includes a valve-closing member, which buts against a through-hole between the feed opening and the discharge opening in a closed position on a valve seat and closes the through-hole, wherein the valve seat includes a stop surface and a sealing surface which are oriented so as to be adjacent to one another, the valve-closing member includes a supporting surface and a gasket surface which are oriented so as to be adjacent to one another, an elastic sealing element is provided on the valve seat or the valve-closing member, on which sealing element the sealing surface or gasket surface is formed, a sealing projection is provided on the sealing surface or the gasket surface and is oriented towards the opposite gasket surface or sealing surface, the supporting surface of the valve-closing member and the stop surface of the valve seat but against one another in the closed position and form a travel limitation between the valve-closing member and the valve seat, and the sealing projection is at least partially pressed into the sealing element.

A valve member is movably provided in a fluid passage to open or close the same. A seal ring is movably assembled to a valve-side annular groove formed in an outer peripheral portion of the valve member. A fluid escape portion is formed on a downstream-side ring surface of the seal ring. A recessed portion is formed as the fluid escape portion and located at a radial-inside position of a sealing surface portion, which is a part of the downstream-side ring surface and tightly in contact with a downstream-side groove surface of the valve-side annular groove when the valve member is moved to a valve closed position. Fluid flows from an upstream side to a downstream side through the fluid escape portion when the valve member is moved to a valve opened position, so that the seal ring is prevented from coming out from the valve-side annular groove.
