In a hydraulic schematic, which component may be shown many times to indicate duplicates without implying there are more than one of that component?

In a hydraulic schematic, which component may be shown many times to indicate duplicates without implying there are more than one of that component?

• A. Pump
• B. Cylinder
• C. Vented reservoir
• D. Directional control valve

Answer: (C)

In hydraulic diagrams, some parts are drawn in multiple places to show that they’re the same physical unit used in different parts of the circuit, rather than separate copies. The vented reservoir is a common example: you can reuse the reservoir symbol in several spots to connect different branches to the same tank, while a vent indicates it’s open to the atmosphere. This helps keep the schematic readable without implying there are multiple reservoirs. Other components like pumps, cylinders, or directional control valves are typically shown where they exist physically; duplicating those symbols would suggest multiple identical devices, which isn’t what the diagram convention is conveying in this context.
