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.

Abstract: Inserts disposed in a housing of a pneumatically or hydraulically powered tool having a motor adapted to rotate a drive lug in either of first and second rotational directions. The insert is composed of a material resistive to creep and/or stress relaxation. The insert contacts fasteners applying a clamping force to the tool and remove the housing from the load path of the clamping force, thereby reducing the possibility of fluid leaks.

Abstract: A reversing mechanism for a pneumatically or hydraulically powered tool having a rotor adapted to selectively rotate in either one of first and second rotational directions. The reversing mechanism allows a user to actuate a button that rotates a valve to direct air flow through the tool. By pressing the button, the button will move a base laterally, and in doing so, rotates the valve. Rotating the valve distributes fluid to cause the rotor to rotate in a selected rotational direction.
