2.1 Short description

• Semi-hermetic six-cylinder reciprocating compressor with suction gas cooled driving motor.
• The flow of refrigerant sucked in from the evaporator is led over the engine and provides for a

particularly intensive cooling. Thus the engine can be kept on a relatively low temperature level
specially during high load.

• Oil pump independent of direction of rotation for reliable and safe oil supply.
• One decompression valve each on the low and high pressure side, which vent into the atmos

-

phere when inadmissibly high pressure levels are reached.
