Abstract
594,849. Rotary pumps and compressors. LEWIS, T. M., PONCE, E. G., and HILLS, A. E. July 2, 1945, No. 16810. [Class 110 (ii)] [Also in Group XXXV] The rotor of an electrically-driven pump or compressor of the outwardly-sliding vane type is disposed between two stators having metallic laminations providing radial pole faces and having windings thereon embedded in a suitable non-conducting material. The electric motor is of the induction type. The rotor e is eccentrically disposed within a casing a and is provided with vanes i sliding in radially disposed slots h. The vanes may be pressed outwards by springs. The rotor body is of non-magnetic conducting material, and has rotor bars g extending through two sets of annular laminations f. The latter are arranged in annular recesses in the rotor body. The laminations c of the stator are set in annular recesses in end plates b, and are formed with radial slots to accommodate windings d. According to the Provisional Specification, the vanes are carried by rods or stems of T-form, the heads of which run in T-slots in the casing ; there may be an axial sleeve valve to control the flow of fluid.
