Rotating valve assembly

摘要

A valve 100 includes a valve housing having an upper body portion 20 and a lower body portion 30 and a generally spherical valve member 50. The upper and lower body portions of the housing define an internal chamber 16 for accommodating the valve member 50 and a central axis for the valve. The valve member 50 is seated within the internal chamber of the valve housing and has an axial bore 52 extending therethrough. The valve member is movable between an open position where the axial bore of the valve member is axially aligned with the inlet and outlet ports of the valve housing, and a closed position where the axial bore of the valve member is out of alignment with the inlet and outlet ports of the valve housing. A camming mechanism for moving the valve member between the open and closed positions includes cam lobes 60a, 60b on valve member 50 and cam pin 22 that extends radially inwardly from an interior surface of the upper body portion 20.
