Abstract

The invention relates to mechanical engineering, in particular to the hydraulic roller pumps.The roller double-acting pump comprises a stator (1) with the surface of its cavity of oval shape, closed at the ends, and two suction (2) and two pumping ports (3), placed opposite the cylindrical surface of a rotor (4), mounted on the shaft of an electric motor; on the cylindrical surface of the rotor (4) are made longitudinal grooves (6) closed at the ends, in which are placed rollers (7), at the same time in the rotor (4), adjacent the grooves (6), are made pockets (5).
