Hydraulic Components 2

Into how many groups are aircraft reservoirs generally divided?

• Three

• Four

• Two

• Five

What is the purpose of an unpressurized aircraft reservoir?

• To store fluid without pressure

• To heat the fluid

• To filter the fluid

• To cool the fluid

What happens to the voids during cavitation when subjected to higher pressure?

• They expand and cool the liquid

• They implode and can generate an intense shockwave

• They remain stable and unchanged

• They dissolve into the liquid

What does the force of a collapsed bubble act like on the lines?

• A feather

• A hammer

• A sponge

• A brush

Where is the bleed air taken from in the turbine bleed air method?

• Compressor section of a turbine engine

• Exhaust section of a turbine engine

• Intake section of a turbine engine

• Combustion section of a turbine engine

What is the function of the venturi fitting in the fluid return line?

• To increase the pressure in the reservoir

• To create a low pressure area that draws in air

• To filter the air entering the system

• To heat the fluid in the return line

Which component is used to indicate the fluid level in a non-pressurized reservoir?

• Vent

• Sight glass

• Baffle

• Stand-pipe

What is the normal fluid level indicator in a non-pressurized reservoir?

• Vent

• Sight glass

• Finger strainer

• Baffle

How is pressure generated in a hydraulic system?

• By heating the fluid

• By placing a restriction in the line

• By increasing the fluid volume

• By compressing the fluid

What does a double action hand pump do on every stroke of the piston?

• Moves a metered amount of fluid

• Stops fluid movement

• Increases fluid temperature

• Decreases fluid pressure
