Patent abstract
An apparatus comprises a valve body having a cylindrical bore centered on an axis. A cylindrical core extends axially within the bore and is fixed relative to the valve body. A sleeve within the bore extends circumferentially about the core and is rotatable about the axis relative to the core. A passage extends radially through the sleeve and provides a radial flow path from the core through the passage to the valve body. Alignment of the passage is circumferentially selectable by rotation of the passage with the sleeve about the axis.
