Abstract
The present invention relates broadly to a flow diverter disposed in a plenum area of a motor cylinder chamber (also referred to as kidney ports). The flow diverter acts as a barrier between a main inlet to the motor and an inlet to the cylinder chamber, and directs air or fluid to vane lifter ports of the motor before the air or fluid flows to the inlet to the cylinder chamber. In addition, the flow diverter can serve to regulate air or fluid flowing into the cylinder chamber to control power of the tool. The flow diverter allows for numerous options of where the main inlet to the motor can be positioned and provides a means of regulating the air or fluid flowing into the cylinder chamber.
