5 About this product
5.1 Performance description
The axial piston variable pump generates, controls and regulates a hydraulic-fluid
flow. The A10VO is designed for mobile applications such as construction machinery.
The A10VSO is designed for stationary applications such as tooling machines.
Refer to data sheets 92701 and 92711 and the order confirmation for the technical
data, operating conditions and operating limits of the axial piston unit.
5.2 Product description
The A10VO and A10VSO 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 (14). For axial piston units with swashplate design, the pistons are arranged
axially relative to the drive shaft (1).
Open circuit
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.
