Abstract
An oil separator element of the type that is used, for example, for the separation of oil from blow-by gases in internal combustion engines is disclosed.The oil separator element has a housing which forms a cavity through which the gas can flow. The housing has an interface which divides the oil separator element into two element halves. Each of the element halves has a groove family in the interface. The grooves of the two families thereby run at an angle to one another in the interface and at least some of the grooves intersect one another.In an oil separator element of this type, the air flowing through is set in rotational motion so that both on account of the centrifugal forces that occur as well as the impact of the oil mist or the oil droplets that are contained in the gas that is carrying the oil, these oil droplets or oil mist are separated on the walls of the grooves.
