Aircraft Elements Flashcards
Check valves are desired when?
we want a fluid to flow in one direction only
Check valves are used in?
hydraulic and pneumatic systems
Pressure relief valves are used -
with pneumatic, hydraulic and oil systems.
When pressure need to be relief due to temperature, what type of relief valve is used?
Thermal relief valve
Selector valves are used -
to control the direction of movement of a fluid operating an actuating point.
Restrictors are used to -
restrict the speed of flow to the required system
The two classes of hydraulic pumps?
constant displacement and variable displacement
The constant displacement pump provides a -
given amount of fluid each time it rotates and requires a pressure regulator or relief valve to prevent excessive pressure.
The variable displacement pump provides a -
fluid output that varies according to the demands of the system
what type of pump is the gear type pump?
constant displacement pump/positive displacement pump
The type of pump connected to a rocker arm, to the a camshaft, is?
the diaphragm type pump
which class of pump is the diaphragm type pump?
constant displacement pump
Which class of pump is the vane type pump?
constant displacement pump
The type of pump that can be both constant and variable displacement type?
piston type pump
The amount pressure that can be generated by a piston type pump?
3 000 psi
