Sealing Device For A Piston Rod Of A Reciprocating Compressor
Patent No. EP4409138 (titled "Sealing Device For A Piston Rod Of A Reciprocating Compressor") was filed by Hoerbiger Wien on Nov 14, 2023. The application was issued on Jan 29, 2025.
Patent Summary
Sealing device for reciprocating compressors that provides a reliable seal at standstill without external energy sources. The device features a unique uncut packing ring with a continuous inner sealing surface that expands radially to form a tight seal at low temperatures. As the compressor operates and reaches higher temperatures, the ring detaches from the piston rod, allowing normal operation. The ring then re-seals when the compressor cools back down, eliminating the need for external activation mechanisms or pressure sources.
