A10V Pump Components and Functionality

A10V pumps utilize an axial piston design, featuring a variable displacement mechanism and often incorporating a DFR (NG 140) control valve for precise operation.

Axial Piston Design Explained

Rexroth A10V pumps employ an axial piston design, a cornerstone of hydraulic power transmission known for its efficiency and durability. This design utilizes multiple pistons arranged parallel to the drive shaft, operating within cylinders. As the drive shaft rotates, the pistons reciprocate, drawing fluid during the intake stroke and delivering it under pressure during the discharge stroke.

The angle between the pistons and the drive shaft is crucial, defining the pump’s displacement characteristics. The swashplate, a key component, dictates this angle, allowing for variable displacement control. Precise manufacturing and material selection are paramount in axial piston pumps to withstand high pressures and ensure a long service life. Understanding this fundamental design is essential when referencing a Rexroth A10V service manual PDF for maintenance or repair procedures.

Variable Displacement Mechanism

The Rexroth A10V series achieves variable displacement through a sophisticated swashplate mechanism. This allows the pump’s output flow to be adjusted proportionally to the swashplate angle. A control mechanism, often hydraulic or electro-hydraulic, precisely alters this angle, enabling precise control over the pump’s delivery volume.
