5 About this product
5.1 Performance description
The axial piston variable pump generates, controls and regulates a hydraulic-fluid
flow. The A10VO and A10VNO are designed for use in mobile applications,
e.g. construction machines. The A10VSO and A10VSNO are designed for use in
stationary applications, e.g. tooling machines.
Refer to data sheet 92703, 92735, 92741 and the order confirmation for the
technical data, operating conditions and operating limits of the axial piston unit.
5.2 Product description
The A10VO, A10VSO, A10VNO, A10VSNO are variable pumps with axial piston
rotary group in swashplate design for hydrostatic drive in an open circuit. Flow is
proportional to drive speed and displacement. The flow can be steplessly changed
by controlling the cradle(13). For axial piston units with swashplate design, the
pistons(11) are arranged axially to the drive shaft(1).
In an open circuit, the hydraulic fluid flows from the reservoir to the hydraulic pump
from where it is fed to the consumer, e.g. hydraulic motor. From the consumer, the
hydraulic fluid flows directly back to the reservoir.
