Abstract: In order to improve an oil separator unit, in particular an oil separator unit provided for vehicle drives, comprising an oil separator housing with a drainage system and a check valve unit which is formed from a valve seat and a valve element which comprises a valve member of an umbrella-like design and consisting of an elastomer, in such a manner that it can be produced as inexpensively as possible, on the one hand, and, on the other hand, the wear on the valve element is, however, considerably reduced or occurs to as low a degree as possible, it is suggested that the valve member of the valve element be held on an insert part and that the insert part be insertable, for its part, into an insert part receptacle in a valve housing.

Abstract: A separator for separating liquid droplets from an aerosol is provided, including a rotor arranged in a housing and including a plurality of parallel disks, a dirty gas inlet, a clean gas outlet, and an annular space between the rotor's circumference and the housing, wherein adjacent disks form an interspace therebetween, the radially outer area of the interspace opening into the annular space, and wherein one of the dirty gas inlet and the clean gas outlet communicates with the annular space and the other communicates with radially inner areas of the interspaces. The disks have flat disk bodies perpendicular to the rotor axis, and between adjacent disk bodies, there are a plurality of adjacent channels allowing passage of the gas to be cleaned. Each channel is curved and the radially outer channel wall forms an impaction and separation surface for the liquid droplets.

Abstract: Separating device for separating liquid or solid particles from an aerosol stream, comprising an impactor with a perforated plate against which the stream flows, and an impact plate arranged at a short distance behind the perforated plate, the side of the impact plate against which the stream flows having a separating layer with an open structure; in order that the separating device will have a consistently good separating effect during operation, the perforated plate is provided on its rear side with a plurality of spacer elements bearing against the region of the separating layer against which the stream flows, the height of the spacer elements, the support surfaces formed by the spacer elements for the separating layer, and the number and arrangement of the spacer elements being selected in dependence upon the material of the separating layer such that it is ensured that the holes of the perforated plate remain free from material of the separating layer also during operation.
