The pneumatic tool includes a housing which encloses a majority of the pneumatic tool. The housing is comprised of a body and a handle depending from the body and defining an input air passageway. A reversing valve lies partially disposed within the housing, intermediate the body and the handle. The body defines a preferably cylindrical motor cavity communicationg at its bottom with the input air passageway and at its top with an exhaust passageway located above the motor cavity. A pneumatic motor is disposed within the motor cavity. The pneumatic motor can include front and rear plates, a rotor rotatively suspended between the plates, and a cylinder disposed between the plates and in sealed engagement thereto. The cylinder has an upper portion with an exhaust port communicating with the exhaust vent and a lower portion with an air inlet communicating with the input air passageway to provide a substantially diametral airflow path through the motor.
A method of providing a generally lateral path without major bends through a pneumatic tool which includes a housing defining a motor cavity and an air inlet passageway into vent opening communicating with the motor cavity, a cylinder disposed in the motor cavity and having an air inlet and an exhaust port extending therethrough for respectively communicating with the air inlet passageway and the vent opening, and a rotor suspended in the cylinder for rotation about an axis, the method comprising:
