What type of output does a variable displacement pump provide?

A variable displacement pump is designed to adjust its output flow rate based on the demands of the hydraulic system it serves. This capability allows it to provide a varying output that can increase or decrease in response to changes in system pressure and flow requirements. By facilitating this adaptability, variable displacement pumps enhance system efficiency and performance, ensuring that the right amount of fluid is delivered for the application at hand.

In contrast, other types of output mentioned do not accurately describe the nature of variable displacement pumps. For instance, a constant output, intermittent output, or fixed output at high pressure do not reflect the primary advantage of variable displacement pumps, which is their ability to dynamically adjust to meet varying operational conditions.
