Abstract
The invention relates to a device for separating liquids from gases, especially for separating oil particles from blow-by gases of the crankcase ventilation of internal combustion engines. Proceeding from the drawbacks of the known prior art, a device is to be provided that is characterized by a simple, cost-effective and space-saving construction and with which a high separation performance can be achieved. As a solution, it is proposed that the individual flow tubeshave at least one tangentially arranged gas inletat their end facing towards the direction of gas inlet and are closed at the front sideadjacent thereto by means of a cover, wherein a combined rotational and axial flow with a vortex component is generated in the flow tubes, wherein the rotational flow in the individual tubesrepeatedly rotates by 360°. The individual flow tubesare part of a base support that has a circumferential edge. A base support has, for example, from 30 to 40 flow tubesthat are immediately adjacent to one another or are arranged in the form of groups. The flow tubeshave an inner diameter D of, for example, 5 mm and a length of from 10 to 20 mm. Due to the tangential introduction, the gas flow reaches higher rotational frequencies, and greater centrifugal forces are produced, whereby a clearly improved separating performance is achieved. The device may be designed as a very small and effective component that requires only a small installation space.
