Abstract
A screw-type compressor, in particular for use in a vehicle, wherein the screw-type compressor has an oil sump with a device for damping sloshing of oil. A screw-type compressor is made available in which the device for damping sloshing of oil is improved compared to the prior art. The device for damping sloshing of oil is a barrier device which prevents the oil from rising up a housing wall of the screw-type compressor.
Claims5
An oil sump for a screw-type compressor comprising:
- a multistage design device for damping sloshing of oil, wherein the oil sloshing damping device is a barrier device preventing oil from running up a housing wall of a housing of the oil sump above the barrier,
- wherein the multistage design device comprises two perforated plates lying in parallel planes perpendicular to the force of gravity acting on the oil included in the oil sump, and
- wherein the perforations of each plate are offset to one another in the housing of the oil sump so that oil flowing out of a separator of the screw-type compressor passes through the two perforated plates in the oil sump and oil in the sump is prevented from running up on the housing wall and returning to the separator.
An oil sump for a screw-type compressor comprising:
- a multistage design device for damping sloshing of oil, wherein the oil sloshing damping device is a barrier device preventing oil from running up a housing wall of a housing of the oil sump above the barrier,
- wherein the multistage design device comprises two perforated plates lying in parallel planes perpendicular to the force of gravity acting on the oil included in the oil sump, and wherein the perforations of each plate are offset to one another in the housing of the oil sump,
- wherein the two perforated plates comprise holes of varying diameter, wherein the diameters of the holes are smaller in regions closer to the housing wall than in the middle of the oil sump.
