How is hydraulic fluid made to flow in the desired direction?

Hydraulic fluid is made to flow in the desired direction primarily by using a hydraulic pump. The function of the hydraulic pump is to generate the hydraulic pressure necessary to move the fluid through the system. When the pump operates, it draws fluid from the reservoir and forces it into the hydraulic lines, creating a flow that can be directed to various components, such as cylinders or motors, depending on the design of the system and the positioning of valves.

The hydraulic pump not only initiates the flow but also maintains it, providing a continuous supply of pressurized fluid to perform the desired work, whether that is lifting, pushing, or moving parts within the hydraulic system. This capability is fundamental in various hydraulic applications, ensuring that the fluid moves where needed to achieve the intended mechanical function.

Other components mentioned, such as pressure relief valves, collector blocks, and accumulators, play supportive roles within the hydraulic system, but it is the hydraulic pump that is primarily responsible for directing the flow of fluid.
