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.

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 [(3)] that is wedged in an accommodating bore [(2)] of a housing [(11)]. The calked joint is configured as a calking cone [(1)] so that the accommodating bore [(2)] forms a funnel-shaped contraction in the direction of the closure member [(3)], said contraction covering the periphery of the closure member [(3)] in the area of a collar [(4)], and succeeding the calking cone [(1)] is a second housing step [(6)] that is expanded in relation to the first housing step [(5)], said step [(6)] being formed by the housing material deforming plastically to the funnel-shaped contraction of the accommodating bore [(2)].

Abstract: The invention relates to an electromagnetic valve, with a valve tappet guided in a valve housing that exhibits a valve-closing element, with a valve-seat holding element facing the valve-closing element, which forms an independent subassembly together with the valve housing, as well as with an armature that activates the valve tappet and can be excited by means of a valve coil arranged on the valve housing. The armature is designed as a cold extrusion pressed part and the valve housing is designed as a deep drawn part or cold extrusion pressed part.
