Rexroth Axial Piston Variable Pump A11VLO Description

The A11VLO variable axial piston pump of swash plate design for hydrostatic drives in open circuit hydraulic system

- Designed primarily for use in mobile applications.

- The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).

- A comprehensive range of control options is available matching any application requirement.

- Power control option is externally adjustable, even when the pump is running.

- The through drive is suitable for adding gear pumps and axial piston pumps up to the same size, i.e. 100% through drive.

- The output flow is proportional to the drive speed and infinitely variable between qV max and qV min = 0.

- Control devices: LR, LR.C, LR3, LG1, LG2, DR, DRS, DRL, DH1, DH2, DH.D, DH.G, EP1, EP2, DE.D, EP.G, etc.

What is the working principle of Rexroth A11VLO hydraulic pump?

The working principle of A11VLO pump is that the displacement of the pump chamber is brought about by the movement of the pistons, so that the fluid is compressed and the fluid has pressure energy. It is a hydraulic component that provides pressurized fluid for hydraulic transmission. Its function is to convert the mechanical energy of power machines, such as motors and internal combustion engines, etc., into liquid pressure energy. The cam is rotated by the motor. When the cam pushes the pistons upwards, the sealing volume formed by the pistons and the cylinder decreases, and the oil is squeezed out of the sealed volume and discharged through the one-way valve to the desired place. When the cam rotates to the lower part of the curve, the spring forces the piston downwards to form a certain degree of vacuum, and the oil in the tank enters the sealed volume under atmospheric pressure. The cam keeps the piston moving up and down, the volume of the seal periodically decreases and increases, and the pump continuously sucks and discharges oil. The necessary condition is that the pump chamber has a sealed volume change.
