Abstract
The present invention relates to a closure device, in particular for closing ducts in a valve-accommodating member in which pressure medium is conveyed, comprising a rotationally symmetric closure member that is wedged in an accommodating bore of a housing. The calked joint is configured as a calking cone so that the accommodating bore forms a funnel-shaped contraction in the direction of the closure member, said contraction covering the periphery of the closure member in the area of a collar, and succeeding the calking cone is a second housing step that is expanded in relation to the first housing step, said step being formed by the housing material deforming plastically to the funnel-shaped contraction of the accommodating bore.
