Producing pressure-tight hollow body to predetermined medium, comprises joining two body parts, which when assembled, form hollow body containing medium in gaseous and/or liquid form, or by sealing single body which forms hollow body

摘要

Producing a hollow body (1) which is pressure-tight to a predetermined medium (2), comprises joining at least two body parts, which when assembled, form a hollow body containing the medium in a gaseous and/or liquid form, or by sealing a single body which forms the hollow body in the closed state and contains in the medium in gaseous and/or a liquid state normal conditions. At least two body parts are joined in a material fit manner. The body is sealed in a material fit manner. The medium which is in the solid or semi-solid state is placed in at least one part of a hollow chamber (7). Producing a hollow body (1) which is pressure-tight to a predetermined medium (2) comprises joining at least two body parts, which when assembled, form a hollow body containing the medium in a gaseous and/or liquid form, or by sealing a single body which forms the hollow body in the closed state and contains in the medium in gaseous and/or a liquid state normal conditions. At least two body parts are joined in a material fit manner. The body is sealed in a material fit manner. The medium which is in the solid or semi-solid state is placed in at least one part of a hollow chamber (7) of at least one body part and the medium are placed together prior to carrying out the material fit joining. The material fit joining is carried out. The medium which is in the solid or semi-solid state is used in hollow chamber of the body prior to carrying out the material fit joining. An independent claim is also included for a piston rod comprising pressure-tight hollow body having a hollow chamber forming body parts or a hollow body, where the hollow body is sealed in material fit manner and the hollow chamber contains the medium which is in gaseous and/or a liquid state.
