ECS parts
Flow limiters
Flow limiter limits the quantity of air by throttling depending on the difference of air pressures at the front of and beyond the limiter.
LUN 5683.5-8, LUN 5684.5-8Water separator
Water separator entraps a part of condensed water vapors in the cockpit air. It is installed in the cold section of the air-conditioning system after turbo-cooler.
LUN 5682.5-8Air shower valve
The air shower valve is designed for blowing over the pilot's face with cold or warm air. The blowing intensity is controlled by turning collar, which through the fork revolves a cone, which in turn is slid in or out, changing the cross sectional area of throughflow of the valve. The outlet part of the valve can be revolved in the valve joint to change the direction of blown air.
LUN 5675.52-8Pressure control valve
The pressure control valve is a device which maintains a constant outlet pressure of air.
Pressure control valve is a pneumatic regulation device, which final control element allows warm air to floe into the cockpite air piping and maintains controlled air temperature in the piping.
LUN 5666-8, LUN 5687.5-8Turbocooler
The turbocooler is a device designed for cooling the air supplied into the aircraft cockpit from the jet engine compressor via the air/air heat exchanger. Besides cooling of the aircraft cockpit, the expansion turbine of the turbocooler drives the turboblower, which suctions the atmospheric air through the heat exchanger.
LUN 5680.5-8Precoolers
The precooler is designed for cooling the air flowing from the jet engine compressor in two separate compar
tments. LUN 5664-8, LUN 5681.5-8Geared motor
The geared motor is designed for driving the closing valve LUN 5663-8 and other equipment of aircraft systems, for which is torque and robustness are applicable.
LUN 5668-8Closing valve
The closing valve closes the air supply from the compressor motor into the air-conditioning or defrosting circuit.
LUN 5663-8Excess pressure regulator
Excess pressure regulator is designed for priority air supply into the special equipment branch.
LUN 5660-8Thermostats
The thermostat with filter works as a temperature sensor on bi-metal principle, this property is used for regulation of air pressure control.
LUN 5689.5-8, LUN 5690-8Inlet filter
Inlet filter is a front device of the control branch of pneumatic control of the air-conditioning system. It supplies clean air for correct function of the pneumatic control equipment.
LUN 5685.5-8Temperature selector
Temperature selector is designed for fine regulation of pressure of control air supplied to the control valve nozzle.
LUN 5686.5-8
