The output volume of a variable displacement rotary piston pump can be changed only by __________.

Question 1 of 27070

The output volume of a variable displacement rotary piston pump can be changed only by __________.

🔍 Key Concepts

• Variable displacement pump vs fixed displacement pump • How piston stroke length is changed in a rotary piston (axial piston/swashplate) pump • Which component controls the angle between the piston block and drive shaft

💭 Think About

• Identify which choice describes changing the geometry of the pistons’ movement rather than just spinning them faster or slower • Ask yourself: in a variable displacement pump, what has to change so that each piston moves a shorter or longer distance per revolution? • Match the names in the choices (trunnion block, tilting plate, slide block and rotor) to the part that actually tilts or re-angles the piston cylinder block

✅ Before You Answer

• Verify which component directly changes the stroke length of the pistons per revolution • Confirm which option changes displacement per revolution, not just flow caused by speed change • Be sure the option you pick is the one that physically alters the tilt/swash angle that the pistons follow

Question 1 of 27070

The output volume of a variable displacement rotary piston pump can be changed only by __________.

changing the speed of the pump

moving the shaft trunnion block

changing the angle of the tilting plate

moving the slide block and rotor
