AXIAL PISTON PUMP WITH ENERGY RECOVERY

摘要

An axial piston pump with energy recovery comprising a rotor having a cylinder block provided with channels for pumped liquid which are connected to the piston cavity of the cylinders, and channels for a liquid which is used for energy recovery which are connected to the rod cavity of the cylinders, and provided with through-channels of a stator, the flat surface of which comes into contact with the end face of the rotor. The rotor comprises a plate which is provided with through-channels for a pumped liquid and channels for a liquid which is used for energy recovery. Said plate has a flat surface which comes into contact with a flat surface of the stator, and an opposite embossed surface which comes into contact with an embossed surface of the end face of the cylinder block and which is installed on the cylinder block at the end face of the rotor so as to be able to move along the rotor axis and at an angle relative to the rotor axis while the flat surface thereof is pressed against the flat surface of the stator by means of a spring.
