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.

The invention claimed is: 1. An apparatus comprising: a valve body having a cylindrical bore centered on an axis; a cylindrical core extending axially within the bore and fixed relative to the valve body; a sleeve within the bore extending circumferentially about the core and rotatable about the axis relative to the core; a passage extending radially through the sleeve and providing a radial flow path from the core through the passage to the valve body, alignment of the passage being circumferentially selectable by rotation of the passage with the sleeve about the axis; a tool housing interconnected with the body, the core and the sleeve as parts of a unitary handheld tool; and a switching arm fixed to the sleeve and extending outward from the valve body and the housing to enable the sleeve to be rotated by manually rotating the arm. 2. An apparatus comprising: a valve body having a cylindrical body surface that defines a cylindrical bore centered on an axis and that has first and second body ports circumferentially spaced apart; a cylindrical core extending axially within the bore and fixed relative to the valve body; and a sleeve, within the bore, extending circumferentially about the core, and including a radially inner surface engaging the core, a radially outer surface facing and spaced from the body surface, a passage extending radially through the sleeve and providing a radial flow path from the core through the passage to die valve body, and a passage structure surrounding the passage from the core to the body surface, the sleeve being rotatable about the axis relative to the core between a first, second and third positions; the first position providing a first radial flow path extending from the core through the passage to the first body port; the second position providing a second radial flow path extending from the core through the passage to the second body port; and the third position providing a circumferential flow path extending from the first body port to the second body port, between the sleeve outer surface and the body surface. 3. An apparatus comprising: a valve body having a cylindrical body surface that defines a cylindrical bore centered on an axis and that has first, second and third body ports circumferentially spaced apart; a cylindrical core extending axially within the bore and fixed relative to the valve body; a sleeve, within the bore, extending circumferentially about the core, the sleeve including a radially inner surface engaging the core, a radially outer surface facing and spaced from the body surface, a passage extending radially through the sleeve and providing a radial flow path from the core through the passage to the valve body, and a passage structure surrounding the passage from the core to the body surface, the sleeve being rotatable about the axis relative to the core between first and second positions; the first position providing a first radial flow path extending from the core through the passage to the first body port and a first circumferential flow path extending from the second body port to the third body port; the second position providing a second radial flow path extending from the core through the passage to the second body port and a second circumferential flow path extending from the first body port to the third body port, with both circumferential flow paths bounded by the sleeve outer surface and the body surface and isolated from the passage by the passage structure; and a tool housing, a bi-directional air motor, an output shaft, and a vent to the atmosphere that are interconnected with the body, the core and the sleeve as parts of a unitary handheld tool, wherein the motor has first and second inlets for receiving pressurized air to power the motor to drive the shaft respectively in forward and reverse directions, the first and second motor inlets respectively communicate with the first and second body ports, and the vent communicates with the third body port. 4. An apparatus comprising: a valve body having a cylindrical bore centered on an axis; a cylindrical core extending axially within the bore and being fixed relative to the valve body, the core having an inlet core port, an outlet core port, a channel system within the core, and an orifice in the channel system, with the inlet core port communicating with the outlet core port through the channel system and through the orifice; a sleeve within the bore, extending circumferentially about the core, overlying the outlet care port and rotatable about the axis relative to the core; a passage extending radially through the sleeve and providing a radial flow path from the outlet core port through the passage to the valve body, alignment of the passage being circumferentially selectable by rotation of the passage with the sleeve about the axis; a plug; and a spring that urges the plug into a closed position in which the plug closes the orifice. 5. The apparatus of claim 4 further comprising a valve stem extending axially from the plug past the outlet core port to a location outside the valve body to enable displacing the plug from its closed position by axially displacing the stem. 6. The apparatus of claim 4 wherein the plug is configured to be urged into the closed position by air entering the core through the inlet core port. 7. An apparatus comprising: a valve body having a cylindrical bore centered on an axis; a cylindrical core extending axially within the bore and fixed relative to the valve body, the core having an inlet core port, an outlet core port, and a channel system within the core through which the inlet core port communicates with the outlet core port; a first sleeve within the bore, extending circumferentially about the core, overlying the outlet core port and rotatable about the axis relative to the core; a passage extending radially through the first sleeve and providing a radial flow path from the outlet core port through the passage to the valve body, alignment of the passage being circumferentially selectable by rotation of the passage with the first sleeve about the axis; a second sleeve extending circumferentially about the core, overlying the inlet core port and rotatable about the axis relative the core; and a nozzle projecting radially outward from the second sleeve and being rotatable with the second sleeve into a range of positions in which the nozzle communicates with the inlet core port through the second sleeve. 8. The apparatus of claim 7 further comprising a circumferential flow space bounded by the second sleeve and the core, through which the nozzle can communicate with the inlet port when the nozzle is rotated to a position in which the nozzle is not aligned with the inlet core port.
