20090108535 | Multipart packing ring - In pressure packings for sealing a piston rod of a compressor, a combination of a radially cut and a tangentially cut packing ring is generally used. These two interacting packing rings must in this case be prevented from rotating relative to one another in order to ensure that the wear gaps are covered by the other ring in each case. The rotation prevention means is generally a pin which is placed in both rings. However, owing to the resulting differing wear to the radially cut and the tangentially cut packing ring, the rotation prevention pins are subjected to shear stress which can cause the pins to break. In order to avoid that, pressure packings are proposed which have individual packing rings and have to be specially cut for this purpose. The present invention describes a packing ring of this type that is distinguished by especially low wear to the ring segments and a long service life associated therewith. The packing ring | 04-30-2009 |
20090289422 | Packing ring combination - Conventional combinations of radially and tangentially cut packing rings require, in particular as wear progresses, a degree of resilient deformation of the resilient packing ring, in order to be able to achieve a satisfactory sealing effect. However, the level of wear achievable is limited thereby. On the other hand, sealing rings which offer a high level of wear and a long service life due to the cut arrangement wear in an uncontrolled manner, which is associated with a risk of damage to or destruction of the sealing rings, resulting in the need for regular maintenance and replacement of the sealing rings. These problems are avoided by a packing ring combination according to the invention consisting of multi-part sealing ring | 11-26-2009 |
20100072712 | Pressure packing comprised of packing rings secured against rotation with injection-molded segments - Conventional anti-rotation devices comprised of packing rings in a packing container of a pressure packing consist of an anti-rotation pin inserted in a packing ring and engaging in a recess at an adjacent packing ring. Due to the different wear rates of the packing rings such anti-rotation pins are subject to shear stress that increases with wear and that can cause the anti-rotation pin to break. Injection-molded packing ring segments with molded anti-rotation nibs in turn require great material thickness for the anti-rotation nibs to be able to withstand the occurring stresses. To solve this problem, the invention suggests to mold a radial anti-rotation groove | 03-25-2010 |

20110298183 | SEALING ARRANGEMENT FOR SEALING A PISTON ROD OF A RECIPROCATING COMPRESSOR - Due to increasingly strict requirements and regulations, it is becoming more and more important for piston compressors to reduce the amount of leakage of operating medium through the seal of the piston rod.
