This represents the integration of electronic control with the fundamental axial piston swashplate pump, enabling precise digital command of hydraulic power in advanced excavators. The core pump structure remains that of a variable displacement axial piston pump. The revolutionary difference lies in replacing the traditional hydraulic servo control for the swashplate with an electro-hydraulic proportional valve (often a solenoid-operated directional valve with proportional spool movement). Principle: An electronic control unit (ECU) receives signals from the operator's joysticks, engine controllers, pressure sensors, and other machine parameters.

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. Each piston features a slipper pad riding on a non-rotating swashplate angled relative to the drive shaft's axis. As the cylinder block rotates, the pistons reciprocate within their bores: moving outward during the half-rotation where the swashplate distance increases (suction stroke, drawing fluid from the inlet port), and being forced inward during the opposite half-rotation where the distance decreases (discharge stroke, pressurizing fluid to the outlet port). The critical structural element for variable displacement is the adjustable swashplate angle. By changing this angle (typically via a hydraulic servo piston controlled by the operator or machine electronics), the stroke length of the pistons is altered. A larger angle increases piston stroke and thus pump displacement (flow rate), while a zero angle results in zero displacement. Key structural components include the drive shaft, rotating cylinder block with precision piston bores, pistons with slippers, swashplate with tilt mechanism, valve plate (stationary, with kidney-shaped ports for inlet/outlet), and a robust housing. In excavators, this design offers exceptional efficiency across a wide operating range, precise flow control essential for coordinated multi-function operation, and high-pressure capabilities needed for digging forces. Its ability to instantly vary flow from zero to maximum based on demand is fundamental to efficient excavator power management.
