摘要： The ball valve according to my invention comprises a pressure-tight housingith at least one inlet-side and at least one outlet-side connecting pipe element, a valve ball made of sintered ceramic material, a valve seat and an operating shaft connected to the ball valve and guide through a shaft seal of the housing. The valve seat comprises seat rings which are clamped between the connecting pipe elements sealing the housing and are compressed on the valve ball. According to my invention the inlet-side seat ring placed on the inlet-side connecting pipe element is made of a flexible sealing material and the outlet-side seat ring put on the outlet-side connecting pipe element comprises a sintered ceramic ring which is inserted in the housing with a sealing element interposed and is resiliently supported on the outlet-side connecting pipe element.

摘要： The connector pipe segment for conductor pipes or conduits for gaseous as well as fluid flow media comprises a pressure-tight outer shell, at least two connector pieces, a plurality of sealing surfaces and a wear-resistant sleeve, advantageously of a sintered ceramic material. The wear-resistant sleeve is inserted in the outer shell and the sealing surfaces are located on the outer shell. The wear-resistant sleeve is inserted with radial play and with axial play free of force in the outer shell so that a gap is formed between the outer shell and the wear-resistant sleeve. The gap is connected with the open cross section of the wear-resistant sleeve and admits the flow media.

摘要： A replaceable tooth article is disclosed for a digging and breaking tool used in a suction head of an excavator consisting of an adapter and a replaceable tooth having a pyramidal outer shape modified with a rounded apex and a plurality of rounded edges. The replaceable tooth is provided with a core composed of a low alloy, temperable and hardenable steel. A tooth peak of hard metal is mounted on the core. The edges of the core extending from the tooth peak are at least partially bevelled. On the bevelled surfaces formed thereby a plurality of edge elements composed of a hard metal, advantageously a carbide metal, are placed so as to form hard metal reinforced edges. All components of the tooth are joined together in a smooth surface.
