Hydraulic System

plays a crucial role in operating various systems, such as flight control surfaces, landing gear, brakes, thrust reversers, and cargo doors. Below are the key components and their functions

hydraulic hoses or tubes capable of handling suction and returning hydraulic fluid back to the system's beginning or reservoir.

stores fluid under pressure at various points in the system, helping dampen pressure surges or supplement the pump during high loads.

It also allows limited system operation if the pump fails.

converts fluid pressure into mechanical force to perform useful work.

Aircraft actuators adjust flight control surfaces, extend and retract landing gear, operate thrust reversers, and open/close cargo doors.

controls the direction of movement for hydraulic actuating cylinders or similar devices. It allows hydraulic fluid to flow both into and out of the unit simultaneously.

limits the pressure exerted on a confined liquid and maintains a steady pressure within a component that operates at a lower pressure than the supply system. This is crucial to prevent component failure or hydraulic line rupture due to excessive pressure.

utilized to stop the flow of fluid to specific systems or components. They also establish priority in hydraulic systems and are controlled by pressure switches.

permits fluid to flow freely in one direction but blocks or limits fluid flow in the opposite direction. It can be an independent component installed in line within the hydraulic system or integrated into other components.

automatically opens under pressure if the filter becomes blocked, ensuring that the fluid cycle continues and the hydraulic system remains operational.

installed for testing purposes when the aircraft is on the ground and the engine is not running, as well as serving as emergency backup units.
