Abstract: In a machine or vehicle component comprising a first housing part, a second housing part covering the first housing part, an opening which is provided in the second housing part, a functional attachment unit incorporating a mounting element consisting of a structurally rigid material which extends through the opening, it is proposed that the problem that the functional attachment unit can only be mounted on the second housing part if the structural rigidity thereof is sufficient to hold the functional attachment unit permanently in a stable position be solved in that the second housing part is formed from a thermoplastic material of low structural rigidity and in that there is provided a carrier which incorporates a carrying element consisting of a structurally rigid material and is fixed relative to the first housing part and upon which the attachment unit is held by means of the mounting element.

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.
