ABSTRACT:
A method of forming a rotor for a vane-type rotary pump. The rotor is generally cylindrical with a plurality of vane slots. A tubular member having generally flat sections separated one from the other by corner portions is formed into the rotor by forming the flat sections into slots by deforming the tubular member. The slots are thereafter formed into the vane slots with a die and the corner portions are formed into the outer peripheral surface of the rotor, also using a die.
