Abstract
A method and device for a fit to size assembly of components or machine parts is provided in which fixed or relatively moving machine parts are sealed against inlet and outlet of a fluid material. A sealing member used for this sealing cannot be put in a position during the assembly, which is required for a fit-to-size assembly. The assembly includes an elastic sealing member inserted into an annular groove that is made in one of the machine parts being sealed relative to another part. The groove communicates with a sealing seat and an overpressure is built up in a space in the groove which is sealed by the sealing member through a passage open to the outside. The overpressure causes the sealing member to move to the sealing seat.
