The rotor is provided with an axially extending sleeve portion having an external annular groove and an axially extending bore terminating within the rotor. One end of a rotatably mounted shaft is accommodated within the sleeve bore. A stationary backing plate is disposed within the housing and encompasses the sleeve portion. The plate is provided with a stepped bore through which the sleeve extends. The stepped bore has a large diameter portion and a small diameter portion, the latter being located between the sleeve external groove and the end face of the sleeve. An annular seal means is disposed within the sleeve external groove and sealingly engages the large diameter portion of the plate stepped bore.
