Abstract
A rotor assembly for a vane motor has a cylindrical rotor body having front and rear shafts extending axially from the front and rear rotor faces, respectively. The rotor is rotatably supported in front and rear bearings and has radial slots extending axially along the rotor body. Radially slidable vanes are provided in each radial slot, and a rear end plate is fixed to the rear face of the rotor body so as to rotate with the rotor and to completely close the slots on the rear face of the rotor. A spacer is provided at the front face of the rotor body to provide clearance for a front end plate which radially circumscribes the front spacer so as to close the radial slots at the front face while still permitting relative rotation between the spacer and the front end plate. The spacer may be integrally formed with the shaft or may be of a separate piece fitting to the shaft.
