The invention relates to a container for fluids having a volume ( ) which can be filled with a fluid, and emptied by pressurizing the fluid by subjecting it to internal gas pressure. The invention is characterized in that the container has a valve device ( ) for filling the volume ( ) with the fluid, while the internal gas pressure is generated by compressing a gas trapped in the container ( ). It is thus not necessary to fill the receptacle with pressure gas separately.

Container for fluids

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.
