The pump is used as a source of energy in different types ofhydraulic driving systems. It has higher efficiency factor. Thepump consists of a casing housing two shafts with parallel axesconnected by two pairs of gear having the same gear ratio one ofwhich is synchronizing and the other operating. In one of therunner wheels (2) mounted on axle (9) radially fitted pistons (8)are mounted. Each piston is in continuous contact with one of thearms of two-arm levers (6) which are placed on pivot support (7)fitted along a periphery on the same wheel. The other arm oflevers (6) is in contact with the second runner wheel (5) being agear wheel with an evolvent teeth profile. The supply anddischarge of the fluid is made by means of chambers designed underpistons (8) and distribution grooves in axle (9).(11) 201
