Latest Patents
Felix Schiefer holds a patent for a high-pressure radial shaft seal with enhanced wear resistance. This invention features a polymer sealing ring, a holding section with a polymer-bonded reinforcement insert, and a sealing lip that extends away from the holding section in the axial direction of the sealing ring. The sealing lip is designed with a first end connected to the holding section and a free second end that includes a sealing edge on the radial inside and a groove on the radial outside. A radially deformable deformation zone is located between the first end and the sealing edge, while a spring in the groove energizes the sealing lip. The sealing ring also has a protrusion that forms an axial stop for the spring, ensuring optimal performance when the sealing lip is deformed radially inwards. This innovative design addresses the challenges faced in high-pressure environments, making it a valuable contribution to the industry.
