A device used to remove oil from the air discharged from an oil-lubricated air pump. A wet, vane-type air pump is lubricated and sealed by a small amount of engine oil flowing through the pump. This oil must be removed before the air can be used.
An oil separator contains a series of baffles over which the pump-discharge air must pass. Any oil in the air sticks to the baffles and drains to the bottom of the separator housing, and from here it is returned to the engine crankcase. Air from which the oil has been removed leaves the separator from a connection above and beyond the baffles.
Industry:Aviation
A device used to separate a liquid mixture or suspension into its various components which have different specific gravities.
A container of the liquid mixture is spun at a high speed, and the components having the higher specific gravities are slung to the outside where they are drawn off.
Industry:Aviation
A device used to transmit indications of angular movement or position from one location to another.
Industry:Aviation
A device used with either a gas turbine engine or a reciprocating engine that can be coupled to the engine to turn it over fast enough for it to start and run normally.
Industry:Aviation
A device which holds the output voltage of a generator or alternator constant as its speed changes in normal operation and its load current changes within its rated value.
Industry:Aviation
A device which opens an electrical circuit when an excess of current flows. A circuit breaker may be reset to restore the circuit after the fault causing the excessive current has been corrected.
Circuit breakers may operate either by heat or a magnetic field, and some have an exposed control so they may be used as a switch as well as a circuit protector.
Industry:Aviation
A device which transforms fluid pressure into mechanical force.
Actuators may be linear, rotary, or oscillating, and they may be actuated by either hydraulic or pneumatic pressure.
Industry:Aviation
A device which uses a piston moving inside a cylinder to change hydraulic or pneumatic pressure into linear (straight line) motion.
Industry:Aviation
A device which visually indicates the direction in which landings and takeoffs should be made. Wind cones, wind socks, and tetrahedrons are commonly used landing direction indicators.
Industry:Aviation
A device worn over the mouth and nose of a person working in an atmosphere of dangerous gases or contaminated air. Some respirators supply oxygen or clean air for the wearer, while others simply filter the contaminants from the air.
