Claim 1
Independent Claim
150 words
A MECHANISM FOR IMPARTING ROTARY MOVEMENT COMPRISING A CYLINDRICAL STATOR MEMBER, A ROTOR MOUNTED WITHIN SAID STATOR, SAID STATOR BEING PROVIDED WITH A CENTRAL HUB, AND NORMALLY HELD AGAINST MOVEMENT RELATIVE TO SAID ROTOR BY AN INTERFERENCE COUPLING BETWEEN THE OUTER FACE OF SAID ROTOR AND THE INNER FACE OF SAID STATOR, AT LEAST ONE OPERATING VANE MOUNTED ON THE INTERIOR OF SAID ROTOR AND EXTENDING INWARDLY THEREFROM INTO CLOSE PROXIMITY WITH HUB OF SAID STATOR, AT LEAST ONE OPERATING VANE CARRIED BY SAID HUB AND EXTENDING OUTWARDLY THEREFROM INTO CLOSE PROXIMITY WITH THE INNER SURFACE OF SAID ROTOR, MEANS FOR INTRODUCING FLUID UNDER PRESSURE AT SAID INTERFACE TO EXPAND SAID STATOR RELATIVE TO SAID ROTOR AND THEREBY UNCOUPLE SAID ROTOR FROM SAID STATOR, AND MEANS OPERATIVE WHEN SAID ROTOR IS UNCOUPLED FROM SAID STATOR ACTING ON SAID VANES TO EFFECT RELATIVE ROTATIONAL MOVEMENT BETWEEN SAID STATOR AND SAID ROTOR.
