Which additional parts are found in vane motors that are not normally found in vane pumps?

Vane motors operate differently from vane pumps, and one significant difference is the presence of springs under the vanes. In a vane motor, springs are used to ensure that the vanes remain in contact with the motor wall during operation, allowing for efficient power transfer and consistent performance. The springs maintain the position of the vanes, ensuring they can adapt to the dynamic changes in pressure and volume of hydraulic fluid, which is essential for converting hydraulic energy into mechanical motion effectively.

While bearings are indeed used in both vane motors and vane pumps to support rotating components, gears are typically part of specific designs for torque conversion and are not a fundamental component of all vane motors. Valves, on the other hand, are crucial in controlling flow and pressure in hydraulic systems but are not unique to vane motors. The specific function of the springs under the vanes is a defining characteristic that sets vane motors apart from vane pumps, underscoring the importance of this design feature in their operation.
