🔍 Key Concepts

• Look at how the drive shaft is drawn in both figures – does its direction of rotation change, or just the angle of the swash plate/tilting plate? • In an axial-piston steering gear pump, changing the tilt of the swash plate affects the direction of oil flow, not the direction of shaft rotation. • Consider what the follow-up gear normally does in a steering gear: does it drive the pump past neutral to the opposite stroke, or does it bring the pump toward neutral as the ordered rudder angle is reached?

💭 Think About

• Compare position I and II and ask: if the shaft kept turning the same way, what would happen to the direction the pistons push oil when the tilting plate is leaned the opposite way? • Think about when you are approaching the ordered rudder angle: should the follow-up gear put the pump on full stroke the other way, or should it reduce the stroke toward zero? • Does changing fluid flow direction in this type of pump require moving a separate six-way valve, or can it be done just by changing the swash plate angle?

✅ Before You Answer

• Verify whether the drive shaft direction is indicated as changing anywhere in the sketch. • Decide whether the swash plate angle alone can reverse the direction of flow while shaft rotation stays the same. • Confirm your understanding of the follow-up action: it should tend to reduce pump output as the rudder reaches its ordered angle, not drive the pump to maximum stroke on the opposite side.
