Technical Description
The axial piston pump with a tilting swashplate is the undisputed workhorse for primary hydraulic circuits in modern excavators. Its core principle involves multiple pistons arranged axially (parallel to the drive shaft) within a rotating cylinder block.
Key features include:
Each piston features a slipper pad riding on a non-rotating swashplate angled relative to the drive shaft's axis
Variable displacement via adjustable swashplate angle controlled by hydraulic servo piston
Precision components including drive shaft, rotating cylinder block with piston bores, and valve plate with kidney-shaped ports
Exceptional efficiency across wide operating range with high-pressure capabilities
Instant flow variation from zero to maximum based on demand
This design offers precise flow control essential for coordinated multi-function operation and is fundamental to efficient excavator power management.
