ADJUSTABLE CIRCULAR PUMP Russian patent published in 2017 - IPC F04C2/344 F04C14/18 

FIELD: engines and pumps.

SUBSTANCE: adjustable circular pump contains a housing inside which a rotor is installed in the form of a shaft with end disks with radial grooves, in which the axes of the rollers located between the discs can be reciprocated. The outer surface of the rollers interacts with the outer surface of the compensating ring, which is freely and eccentrically mounted on the rotor shaft. Inside the case with a possibility of forced reciprocating movement between the discs, the glass with an inner cylindrical surface contacting the outer surface of the rollers is installed. In the shell of the glass, the holes are provided that ensure the flow of pumped medium from the inlet to the outlet holes made in the housing. Bypasses are made in the body. Compensation valves are installed on the shell of the cup from opposite sides.

EFFECT: providing the possibility of capacity control without changing the speed of rotation of the rotor and without significantly complicating the design of the pump.
