11.11 - Hydraulics Flashcards
Some hydraulic reservoirs are pressurised to prevent the pump _______
cavitating
Two methods of pressurizing a hydraulic reservoir are:
- Engine compressor bleed air (APU possibly also.. pnuematically)
- system hydraulic pressure
An engine-driven hydraulic pump is prevented from building up damagingly high pressure if the pressure regulator (constant dispacement pump) and relief valve fail be a/an ________ in the drive shaft
shear section
A mechanically operated flow control valve that prevents fluid flowing to one unit before some other unit has actuated completely is called a/an _______ valve
sequence
A flow control valve that allows full flow in one direction but no flow in the opposite direction is called a/an _____ valve
check
A flow control valve that allows a full flow in one direction but a restricted flow in the opposite direction is called a/an ________
orifice check valve (restrictor valve)
A component that shuts off the flow of hydraulic fluid if a line should rupture is called a hydraulic ______
fuse
