Abstract
A fluid powered mechanism has a housing with a generally cylindrical shape and circumferentially adjacent axially extending primary and secondary fluid passageways. Exhaust direction and rotary limit speed are controlled by a flow reversing and regulating ring having a first face with a thru slot and an adjacent blocking flange and a second face having a turning flange which is the reverse of the blocking flange of the first face. The flow reversing and regulating ring is color coded to indicate the size of the fluid flow passageways and, thus, the limit speed provided by the ring. The rotational limit speed and the exhaust direction are determined by selection of the color-coded flow reversing and regulating ring and by its orientation in the tool.
