Latest Patents
One of Ralf Dedeken's latest patents is a contactless pressurizing-gas shaft seal. This invention features a high-pressure sealing arrangement where a rotor sealing ring end face generates gas pressure with a stator sealing ring end face. The design includes a functional gap between a cylindrical portion of the seal housing and the stator sealing ring, bridged by an O-ring of reduced hardness. The gap width is meticulously designed to be less than 0.4 mm, and preferably less than 0.3 mm. The sealing O-ring also serves as a compensation or centering ring, with a material hardness greater than the extrusion threshold and less than 90 Shore A according to German Industrial Standard DIN 53505. Ideally, the hardness of the O-ring is less than 80 Shore A under this standard. The invention ensures that the orientations of the sealing end faces remain parallel during operation, enhancing the overall performance of the sealing system.
