Definitions
- the invention relates to a rotary oil separator for cleaning crankcase ventilation gases of an internal combustion engine.
- crankcase ventilation gas In all internal combustion engines, oil droplets and oil aerosols are part of the blow-by gases from the crankcase ventilation. When these oil-containing gases are introduced into the intake area of the engine, contamination occurs in the subsequent components, which adversely affect the function of the engine components. The entrained oil must therefore be removed from the crankcase ventilation gas.
- Oil is usually separated from the crankcase gases with the help of separators made from a knitted fabric or with the aid of beam deflections on baffle plates or a combination of these processes.
- separators made from a knitted fabric or with the aid of beam deflections on baffle plates or a combination of these processes.
- ultra-fine filters are used, but they work with a high differential pressure.
- Cyclone separators require a relatively large installation space and, due to their principle, only work optimally at one operating point.
- Electrostatic filters require additional electrical power consumption and are relatively expensive intensive. In addition, these filters cannot be used with flammable gases.
- Rotary oil separators in which the oil droplets are ejected with the help of paddle wheels, are also known. They are usually driven by electric motors, air pressure turbines or oil pressure turbines.
- the invention has for its object to provide an oil separator that ensures almost complete oil separation from the crankcase ventilation gases under all occurring operating conditions and at low differential pressure and can be produced inexpensively.
- a filter disk is attached to a shaft located in the crankcase in such a way that the crankcase gases have to pass through this filter disk.
- the oil and soot particles separated on the surface and on the way through the filter disk are thrown off by the rotating disk and remain in the crankcase, so that no oil collecting space and no special oil return are required.
- the self-cleaning power of the rotating filter disc is so great that the differential pressure of the filter does not change significantly even with long running times.
- An oil separator provided for use in crankcase ventilation systems of an internal combustion engine with a throughflow of air is particularly cost-effective provided for cleaning gases filter disc when the filter disc is attached according to claim 7 on a camshaft, balance shaft or crankshaft of the internal combustion engine.
- the oil separator according to the invention does not require any complex drive, since at least one of the shafts mentioned is present in internal combustion engines anyway.
- a particularly advantageous use of a rotating filter disk provided for the flow of the gases to be cleaned consists in separating oil droplets and oil aerosols from gases from a crankcase ventilation of an internal combustion engine.
- a filter disk can withstand changing load conditions of the internal combustion engine and can permanently clean itself. The separation of oil droplets and oil aerosols from the gases in the crankcase ventilation is therefore almost maintenance-free. Soot particles are also thrown off the filter disc.
- the invention permits numerous embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below.
- this shows a filter disk 1, which is attached to a shaft 2 in the crankcase space 5 of an internal combustion engine, not shown.
- the direction of flow of the crankcase ventilation gases is indicated by arrows.
- the housing bushing 3 is sealed in the crankcase wall 4 and touches the filter disk 1 with its end face.
- the housing bushing 3 is provided with a drip edge 6 so that the oil running off the crankcase wall 4 does not reach the filter disk 1 when the engine is at a standstill.
