What does the rotor in a variable displacement pump do?

The rotor in a variable displacement pump is responsible for adapting the pump displacement. In simpler terms, this means that the rotor's movement allows the pump to change its volume capacity, which directly influences the flow rate of the hydraulic fluid being pumped. By adjusting the angle or position of the rotor, the pump can efficiently control the amount of fluid that is moved through the system, accommodating varying power demands and operational conditions. This capability is crucial for providing versatility in hydraulic systems, allowing for optimal performance under different load situations.

In the context of hydraulic systems, effectively managing displacement can lead to improved efficiency and responsiveness, which are essential for applications that require precise control over fluid flow and pressure.
