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.

Que and rotational speed are applied to the drive shaft (1) by a drive motor. The cylinder (10) is picked up and turned by the splines of the drive shaft.

With every revolution, the pistons (11) complete a stroke in the cylinder bores, the
size of which depends on the pitch of the cradle (13). The slipper pads (12) are held
on with the pistons and guided along the glide surface of the cradle by the retaining
plate (3). The cradle setting during a rotation causes each piston to move over the
bottom and top dead centers and back to its initial position. During this sequence,
hydraulic fluid is fed in and drained out through the two control slots in the control
plate (7) according to displacement. On the suction side (9) hydraulic fluid flows
into the piston chamber as the piston recedes. At the same time, on the high-
pressure side (6) the hydraulic fluid is pushed out of the cylinder chamber into the
hydraulic system by the pistons.

The swivel angle of the cradle (13) is continuously adjustable. Adjusting the swivel
angle changes the piston stroke and, with it, the displacement. The swivel angle is
controlled hydraulically by means of the stroking piston. The cradle is mounted for
easy motion in swivel bearings. When pressurized, the cradle is held in balance by
the swiveling forces of the rotary group, which are generated by the eccentrically
mounted swashplate and by the control pressure. When depressurized, the
spring (2) presses the cradle to maximum swivel angle. Increasing the swivel angle
increases the displacement; reducing the angle reduces displacement accordingly.
