Abstract: An improved pneumatic tool design includes pneumatic motor chamber that houses a turbine. An air path directs compressed air into the pneumatic motor chamber. The air path includes an air inlet chamber that at least partially surrounds the pneumatic motor chamber. The air path also includes a motor inlet disposed in one side wall (e.g., the top wall) of the pneumatic motor chamber forward of the rear end plate thereof. The air path further includes at least one exhaust port disposed in an opposite side wall (e.g., the bottom wall) of the pneumatic motor chamber. A high-pressure seal, such as an o-ring, surrounds the pneumatic motor chamber and isolates the motor inlet, which is thus at a rear outer portion of the pneumatic motor chamber, from a forward outer portion of the pneumatic motor chamber.
