Rexroth A11VO axial piston hydraulic pump parts

The Rexroth A11VO series is a variable displacement axial piston pump designed for open circuits in mobile and industrial hydraulics. Its core components can be grouped into several key categories:

1. Rotating Group: This is the heart of the pump. It consists of a cylinder barrel (rotor) with multiple piston bores, typically nine pistons, and slippers attached via ball joints. The assembly rotates within the housing.

2. Displacement Control Mechanism: The defining feature of the A11VO. It includes a swashplate whose angle is adjusted by a control piston. The angle determines the piston stroke and thus the pump displacement. A control valve, such as a pressure compensator or load-sensing valve, regulates piston movement based on system pressure or demand.

3. Valve Plate (Port Plate): A stationary component mounted between the cylinder barrel and the pump's port block. It contains kidney-shaped inlet and outlet ports that facilitate oil intake and discharge as the barrel rotates.

4. Shaft and Sealing: A robust drive shaft transmits torque from the prime mover. Critical sealing elements include shaft seals to prevent external leakage, as well as various O-rings and gaskets at component interfaces.

5. Housing and Auxiliary Parts: The main housing (casing) encloses all components. Other essential parts include the shaft bushing, port blocks with pressure and tank connections, a drain line for case leakage, and a charge pump (optional for closed-loop variants).

The pump operates based on the rotating group: as the cylinder barrel turns, the pistons reciprocate within their bores while the slippers follow the angled swashplate, causing volume changes that produce the pumping action. The control system adjusts the swashplate angle to vary the output flow smoothly from zero to maximum, making the A11VO highly efficient for applications with variable flow demand.

Parts list

Q1: Which key component is responsible for changing the pump's displacement?

A1:The displacement is changed by the control unit, which typically includes a servo piston that adjusts the angle of the swash plate. The control unit's spool and pressure compensator manage this movement based on system signals.
