To convert a vane type hydraulic pump to a hydraulic motor, which of the following would have to be done?
AI Explanation
The correct answer is B) Provide small springs between the vanes and the base of the vane slots.
To convert a vane type hydraulic pump to a hydraulic motor, the vanes need to be able to retract into the rotor as the motor shaft rotates. Small springs between the vanes and the base of the vane slots allow the vanes to extend outward and contact the casing when driven by the hydraulic fluid, but also retract inward when the shaft is rotated, allowing the motor to function.
The other options are incorrect because they do not address the key requirement of allowing the vanes to retract. Adding an extra slot/vane, enlarging the control ring, or increasing the casing thickness would not enable the necessary vane retraction for converting the pump to a motor.
