Theory
| Category | Description |
| Working Principle | The pistons move reciprocally within the cylinder block, and the swashplate angle changes the stroke volume to regulate oil intake and discharge. |
| Energy Conversion | Mechanical Energy (input shaft rotation) → Hydraulic Energy (high-pressure oil output) |
| Flow Regulation | Swashplate angle adjustment → piston stroke variation → controlled flow output |
| Pressure Maintenance | The system’s relief valve sets the maximum pressure. The pump adjusts flow automatically through pressure compensation to maintain constant pressure. |
