Abstract (en)

[origin: WO8403329A1] A rotor (10) for a vane pump and motor comprises a hollow rotor body (12), end plates (13, 14) welded to both end surfaces thereof, and a rotating shaft (11) secured to the end plates. If required, a heat pipe working fluid could be sealed within the rotating shaft (11) or the rotor body (12). The rotor (10) provided with the rotor body (12), the rotating shaft (11) and the end plates (13, 14) is made of a composite material prepared by mixing whiskers into a matrix metal, and has a sufficiently high strength even if the wall thicknesses are further reduced, so that it is possible to obtain an extremely lightweight rotor.
