Does the vane pump utilize centrifugal force to seal the vane against the cam ring?

The correct answer highlights that a vane pump does indeed use centrifugal force to help seal the vanes against the cam ring. In a vane pump, as the rotor spins, the centrifugal force causes the vanes to extend outward into the cam ring. This action creates a seal between the vanes and the cam ring, allowing the fluid to be transported effectively within the pump.

This sealing mechanism is crucial for the pump's operation as it helps maintain the pressure needed to move the fluid and facilitates the efficient transfer of energy through the pump. As the rotor turns, the movement and position of the vanes are critical for creating the appropriate pressure differentials that allow the pump to function effectively.

Understanding the operating principle of vane pumps, including the role of centrifugal force, is vital in recognizing their practical applications in various fields, particularly in hydraulic systems where consistent flow and pressure are necessary.
