Which term describes a secondary path for fluid flow in a hydraulic system?

• A. Hydraulic Bleed
• B. Hydraulic Bypass
• C. Hydraulic Circuit
• D. Rotary Switch

Answer: (B)

A bypass provides a secondary route for fluid flow in a hydraulic system. It lets part of the fluid skip around a component or a section of the main path, so flow can continue even if a valve is closed or a path is blocked. This is useful for relieving pressure or keeping the system circulating by sending fluid through an alternate route, such as back to the reservoir or to another branch. Bleed areas are for venting air, not creating an extra flow path; a circuit is the whole network of components, and a rotary switch is an electrical device, not a hydraulic flow feature. So the term that describes a secondary path for fluid flow is hydraulic bypass.
