Abstract

The article reviews the possibility to improve efficiency of the cylinders block design and the pumping unit of an axial-piston hydraulic machine by means of utilization of inter-cylinder zones for installing additional chambers smaller in diameter. This design allows to building a new axial piston rotor double row hydraulic machine with two pumping units, which have not been used in hydraulic drives. It is required to increase in the outer diameter of the original cylinders block by only 10% that will provide an increase the working volume and power of the new hydraulic machine by 33%. The updated efficiency improvements do not only increase the working volume and power, but also increase the hydraulic motor acceleration without increasing the feed pulsation, angular velocity and torque on the shaft of the hydraulic machine under investigation.
