2. LUBRICATION SYSTEM
2.1. FUNCTIONAL DESCRIPTION
2.1.1. Compressor Block IK12.14
The compressor is provided with a low pressure lubrication
system. The oil pressure is produced by a low reving gear
pump. The oil pressure is approximately 4.5 bar (3 to 6
bar).
This oil pump will operate in the correct
sense of rotation, only. Otherwise, no oil
pressure will be built up resulting in dam
age of the compressor block.
The oil pump (1, Fig. 12) is coupled to and driven by the
crankshaft. It pumps oil from the oil sump (5) through the
oil fine filter (2) and a minimum pressure valve (3) to the last
stage cylinder. The oil is then distributed by the guide piston
(4) and lubricates all moving parts of the compressor block.
The minimum pressure valve allows for oil pressure indica
tion at a pressure gauge and electronic oil pressure monito
ring.

2.1.2. Compressor Blocks IK150, IK15.1, IK15.11,
IK180, IK18.1
The compressor is provided with a forced-feed lubrication
(Fig. 13). The oil pressure is produced by a low reving gear
pump. The oil pressure is approximately 4.5 bar (3 to 6
bar).
This oil pump will operate in the correct
sense of rotation, only. Otherwise, no oil
pressure will be built up resulting in dam
age of the compressor block.
The oil pump (1, Fig. 13) is coupled to and driven by the
crankshaft. It pumps oil from the crankcase through an oil
fine filter (2) and a minimum pressure valve (4) to the last
stage cylinder. The oil is then distributed by the guide piston
of the last stage and lubricates all moving parts of the com
pressor block.
The minimum pressure valve allows for oil pressure indica
tion at a pressure gauge and electronic oil pressure monito
ring.

2.2. TYPE OF OIL
For proper care and maintenance of the compressor, using
the correct oil is of vital importance. Depending on the ap
plication of the compressor the requirements placed on the
oil are:
 low deposits
 no carbonizing effect, especially in the valves
 good anti-corrosive properties
 emulsification of the condensate in the crankcase
 for breathing air application, also physiological and tox
icological suitability.
Due to the thermal load on the compressor only high quality
oil should be used. You are recommended to restrict oils to
those which have been approved by us and are listed in our
lubricating oil list.
