Abstract
The high pressure rotary pump in a pot housing includes a pressure cap (). The latter has a flange part with a flange () with which the pressure cap is fastened to an end face and annular sealing surface () of a housing () by being screwed into place. The flange is elastically deformed by being screwed into place. The sealing surface of the housing in the region of a base zone of the flange stands in contact on this with a second sealing surface (). The two sealing surfaces () lie on two at least approximately radially extending conical or annular surfaces prior to the being screwed up. These two surfaces enclose an angle χ which opens outwardly with respect to a central axis (). After the screwing into place of the flange, the two sealing surfaces are pressed onto one another due to its elastic deformations and thus the angle between the sealing surfaces is equal to zero.
