Abstract
A pneumatic wrench including a pneumatic motor that includes a rotor, a rotor housing, an endplate, and a wear plate. The rotor has an output shaft configured to rotate about an axis and a plurality of vanes that extend radially from the axis that compressed air exerts work against to drive the rotor. The rotor housing has a cavity configured to house the rotor, receive the compressed air, and direct the compressed air about the rotor and out of the rotor housing. The endplate is coupled to the rotor housing and configured to receive the output shaft. The endplate includes a channel that is in fluid communication with the cavity. The wear plate is disposed between the endplate and the rotor housing and defines an exhaust port between the cavity and the channel for directing airflow from the cavity to the channel in an axial direction.
