This invention relates to a check valve having a straight-through flow passage wherein a ball-plug of a cylindrical geometry with a hemispherical end is pendulously confined in a cavity included in the valve body. The ball-plug has a through-hole with the central axis substantially passing through the center of a spherical surface including the hemispherical end of the ball-plug, which central axis substantially intersects the central axis of the ball-plug in an oblique angle. The ball-plug is pendulously confined in the cavity within the valve body by a...
1. A ball-plug pendulum check valve comprising in combination: (a) a ball-plug of a circular cylindrical geometry having a substantially hemispherical end, said ball-plug including a through-hole with central axis substantially passing through the center of a spherical surface including said hemispherical end of said ball-plug and intersecting with the central axis of said ball-plug in an oblique angle; (b) a valve body including a flow passage extending from one extremity to the other extremity of said valve body and a cavity pivotably housing said ...
