PUMP Russian patent published in 1995 - IPC

FIELD: pump engineering. SUBSTANCE: outlet of the working member made up as a spiral passage is tightly connected to the delivery branch pipe connected with fluid collector. The collector has branch pipes for connecting pipe lines for fluids and gas. The spiral passage is mounted for permitting rotation about its longitudinal axis. The outlet of the passage is immediately connected with the delivery branch pipe which can rotates about the longitudinal axis of the passage. The width of the passage inlet is equal to the width of the working member. The driving unit is constructed as a hoppers uniformly arranged over periphery of the working member. The outlet of the passage can be connected with two delivery branch pipes defined by through axial passage provided in the shaft and coupled with the fluid collector. EFFECT: enhanced efficiency. 4 cl, 8 dwg
