Axial piston variable pump
A4VG
5.1 Performance descriptionThe axial piston variable pump generates, controls and regulates a hydraulic fluid flow. It is designed for mobile applications such as construction machinery.Refer to data sheet 92003 and the order confirmation for the technical data, operating conditions and operating limits of the axial piston unit.5.2 Product descriptionThe A4VG is an axial piston variable pump with swashplate design for hydrostatic drives in closed circuits. The flow is proportional to the drive speed and displacement. The flow can be steplessly changed by controlling the cradle (12). For axial piston units with swashplate design, the pistons are arranged axially relative to the drive shaft.In the closed circuit, the hydraulic fluid flows from the hydraulic pump to the consumer, e.g. hydraulic motor and from there directly back to the hydraulic pump. There is a high-pressure side and a low-pressure side which alternate depending on which side is under load1 Drive shaft2 Retainer plate3 Stroking piston4 Control unit (using the EP as an example here)
