Shuttle valve

A shuttle valve, comprising:

• a valve housing which further comprises:
• at least one inlet aperture;
• and
• at least two outlet apertures, wherein each of said at least two outlet apertures has associated therewith a flow passage,
• and further wherein said valve housing has an inner cavity located therewithin which has spherical seating surfaces located adjacent each of said flow passages;
• a valve assembly wherein said valve assembly is located in said inner cavity of said valve housing and wherein said valve assembly further comprises:
• a valve disk wherein said valve disk has a spherical surface, at least in part, and wherein said spherical surface defines a sphere which has a center point, and further wherein said center point defines a first point location, and
• a flow directing element, wherein said flow directing element is rotatably seated within said valve housing and is rotatable without a prior displacement, and further wherein said flow directing element is connectably attached with said valve disk so that said flow directing element and said valve disk rotate simultaneously with one another;
• a valve shaft assembly which further comprises:
• a valve shaft, wherein said valve shaft extends from said inner cavity to the exterior of said valve housing, and further wherein said valve shaft rotates about an axis of rotation, wherein a horizontal plane is defined by a plane which is perpendicular to said axis of rotation of said valve shaft, and which passes through said first point location, wherein said first point location defines a first point location on said horizontal plane, and further wherein said point of intersection of said axis of rotation of said valve shaft and said horizontal plane defines a second point location on said horizontal plane, wherein said first point location and said second point location are at least one of eccentric with one another and displaced from one another on said horizontal plane;
• and further wherein said valve shaft assembly is connectably attached with said valve assembly so that said valve shaft assembly controls a rotation of said valve assembly, and further wherein the actuation of said valve shaft assembly causes the rotation of said valve assembly within said inner cavity of said valve housing so as to rotate said valve disk from a first flow passage to a second flow passage;
• and further wherein a continued actuation of said valve shaft assembly, along with said first point location and said second point location being at least one of eccentric with one another and displaced from one another on said horizontal plane, provides a seating force, wherein said seating force perfects a seating between said spherical surface of said valve disk and said spherical seating surfaces adjacent said second flow passage.

A shuttle valve, comprising:

• a valve housing which further comprises:
• at least one inlet aperture;
• at least two outlet apertures, wherein each of said at least two outlet apertures has associated therewith a flow passage, and further wherein said valve housing has an inner cavity located therewithin which has seating surfaces located adjacent each of said flow passages;
• a valve assembly, wherein said valve assembly is located in said inner cavity of said valve housing, and wherein said valve assembly further comprises:
• a valve disk, wherein said valve disk is articulated and wherein said valve disk has a spherical surface, at least in part, wherein said spherical surface defines a sphere which has a center point, and further wherein said center point defines a first point location;
• a flow directing element, wherein said flow directing element is connectably attached with said valve disk so that said flow directing element and said valve disk rotate together with one another;
• a valve shaft, and further wherein said valve shaft rotates about an axis of rotation;
• wherein a horizontal plane is defined by a plane which is perpendicular to said axis of rotation of said valve shaft, and which passes through said first point location, wherein said first point location defines a first point location on said horizontal plane, and further wherein said point of intersection of said axis of rotation of said valve shaft and said horizontal plane defines a second point location on said horizontal plane;
• wherein said first point location and said second point location are at least one of eccentric with one another and displaced from one another on said horizontal plane;
• wherein said valve shaft assembly controls the rotation of said valve assembly, and further wherein the actuation of said valve shaft assembly causes the rotation of said valve assembly within said inner cavity of said valve housing so as to rotate said valve disk from a first flow passage to a second flow passage;
• wherein said spherical surface of said valve disk contacts said seating surfaces which are adjacent said second flow passage, and further wherein a continued actuation of said valve shaft assembly in conjunction with said first point location and said second point location being said at least one of eccentric with one another and displaced from one another on said horizontal plane, perfects a seating between said spherical surfaces of said valve disk and said seating surfaces adjacent said second flow passage.
