초록 ▼

A valve casing is provided with a part-spherical interior sealing surface and with three valve ports each open from the outside of the casing and through the part-spherical sealing surface thereof. A part-spherical valve body or ball is mounted in concentric very slightly spaced relation to this sealing surface of the valve casing. The valve body carries a valve seal structure and is provided with a valve body passage extending through the valve body. The valve body is rotatable within the valve casing between: (1) a first position wherein said valve body passage provides a passageway between a first and a second of the ports and said valve seal structure is in sealing relation to the valve casing sealing surface around a third of said ports; and (2) a second position wherein said valve seal structure is in sealing relation around said first port and said valve body passage provides a passageway between said second and third ports. The valve seal structure includes a valve seal ring concentrically mounted in spaced relation to and around a cylindrical boss extending outwardly from the valve body, resilient means tending to move the seal ring away from the valve body and into sealing relation with respect to the part-spherical sealing surface of the valve casing, and an O-ring sealing the space between the valve seal ring and the valve body boss.

A fluid transfer valve including: (a) a valve casing provided with a part-spherical interior sealing surface defining a valve cavity, said casing being provided with at least three valve ports open from outside said casing and through said sealing surface into said cavity; (b) a valve body provided with a part-spherical outer surface forming part of the outer wall of said valve body and defining a sphere of diameter only slightly less than a sphere defined by the part-spherical interior sealing surface of the valve casing; (c) said valve body being provided with a valve passage therethrough; (d) a valve seal structure movable with the valve body and including a portion of said valve body defined by a fluid impervious circular face, an annular valve seal ring in sealing, surrounding relationship to said valve body face, and means to urge said valve seal ring outwardly from said valve body, said valve seal structure being adapted to seal the interior of one of said valve ports from the remainder of the valve cavity and from said passage in the valve body when the valve seal ring is positioned in sealing relation to the casing interior sealing surface in surrounding relation to such port; (e) means for mounting said valve body in said cavity of said casing in concentric relation to the casing for movement of said valve body between a first position wherein said valve seal ring is in sealing contact with said interior sealing surface of said casing in surrounding relation to a first of said ports and said valve passage is aligned to permit flow between a first combination of two of said ports and a second position wherein said valve seal ring is in clearing relation to said first port and said valve passage is aligned to permit flow between a second combination of two of said ports; and (f) means for moving said valve body between said first and said second positions.
