In order to eliminate these problems, a wiper arrangement with a wiper ring | 08-18-2011 |
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. Conventional seals comprising packing rings and/or packing ring combinations always have a certain amount of leakage, both during operation and when at standstill, which is why they are not usable for certain applications, or the complexity involved in such a seal increases considerably. A further problem involving the seals of piston rods relates to transverse movements by piston rods during which the sealing action of the seal must be maintained. Proposed is, therefore, a sealing arrangement according to the principle of a sealing medium barrier providing that the sealing elements | 12-08-2011 |
20120211945 | SEALING PACKING FOR A RECIPROCATING PISTON ROD OF A RECIPROCATING COMPRESSOR - A gas-proof sealing packing of a compressor includes a scraper recess on the crankcase-side end containing a gas-proof scraper ring, a sealing ring recess on the cylinder-side end containing a sealing ring arrangement (18), a barrier recess located axially between the scraper recess (15) and the sealing ring recess (17), and a drain line in the sealing packing that is connected with the space between the barrier recess and the scraper recess. | 08-23-2012 |
