Five working systems
Start with a circuit you can change.
Each diagram comes from the same example used in the workbench. Open its page to see the circuit and what to observe.
Cylinder lift · directional control
A 63/36 × 400 mm cylinder lifts an 18 kN load. Run a capture to see extension, end-stop arrival and the relief valve taking the pump flow.
FundamentalsThrottle · pressure and flow
A variable restriction returns pump flow to tank. Closing the throttle increases pressure until the relief valve diverts excess flow.
ActuationHydraulic motor · torque and speed
A displacement motor drives a 50 N·m load. Change displacement or pump speed and compare pressure, flow and rotational speed.
Energy storageAccumulator · charging cycle
A 2 L accumulator charges from 50 bar gauge precharge. The gas compresses as oil enters; the relief valve limits the final pressure.
Valve controlTandem center · pump unloading
The tandem center connects P to T in neutral while holding A and B. Set the cylinder load to zero to study unloaded holding and compare pump power with extend.
