Abstract

1,145,622. Rotary pumps. TRANSFLO Inc. March 29, 1966 [March 29, 1965], No.6737/66. Heading F1F. A rotary vane pump comprises a hemispherical chamber 20, Figs.2, 3 formed by a hemispherical shell 22 and a flat back plate 24 having a central aperture through which extends a shaft 50 driven by an electric motor 40. The shaft 50 terminates in a rotor 52 having a convex hemispherical surface 54 and diametrally projecting pins 56, 57 which engage a semi-cylindrical recess 68 in an impeller 60 having a pair of semi-annular vanes 62, 64 with a dihedral angle therebetween. The vanes sealingly engage on their outer peripheries the inner wall of the shell 22 and on their inner peripheries the convex surface 54 so that with a frusto-conical member 70 adjustably connected to the shell the chamber 20 is divided into four variable volume compartments, two (A), (B) Fig. 5 (not shown) between the rear faces of the vanes and the back plate 24 and two (C), (D), Fig. 6 (not shown) between the front faces of the vanes, the shell 22 and the member 70. To make sure of sealing contact between the vanes and the member 70 the vanes are made of resilient material, e. g., rubber and the angle between the vanes is slightly less than the conical angle of the member 70 so that the vanes 62, 64 are flexed apart. Preferably however, the front faces of the vanes are provided with ramps conforming to the profile of the member 70. The pump is assembled on the end of a sleeve 36 connected to the motor 40 by means of a bail 30 and a knurled-headed screw 46. The member 70 may be adjusted from a position in which its axis is coaxial with the rotor axis when no pumping takes place to any position above or below the rotor axis to vary the amount of fluid pumped. Depending upon the direction of rotation of the rotor and the adjusted position, above or below the rotor axis, of the member 70, the flow of pumped fluid through ports 82, 84 in the shell 22 may be in either direction. The compartments (A), (B) are arranged out of phase by 90 degrees with respect to the compartments (C), (D) so that as a delivery compartment (C) or (D) is increasing in volume the associated delivery compartment (A) or (B) is decreasing in volume to keep pump delivery substantially constant and avoid turbulence. In a modified drive connection between the rotor 52 and impeller 60, instead of the pins 56, 57 and recess 68, the rotor is slotted on its convex surface to receive a projection formed on the impeller. A spring-loaded collar 96 urges the rotor into sealing contact with the vanes 62, 64.
