piston rod packing and a piston compressor comprising a piston rod packing

摘要

piston rod packing (1) comprising a plurality of in a direction of extent (l) is arranged following one after the chamber rings (2), with therein arranged piston rod seals (3), wherein at least some of the chamber rings (2) cooling channels (2a) and connecting passages (2f), the connecting passages (2f) the cooling channels (2a) of which are arranged successively chamber rings (2) is conductively connect fluid,characterized by the,that the piston rod packing (1) comprises a plurality of piston rod portion packs (1a, 1b, 1c), wherein each piston rod subpack (1a, 1b, 1c) comprises at least two fixedly connected to one another and are arranged following one after the chamber rings (2) with cooling channels (2a) and connecting channels (2f), wherein in each chamber ring (2) has a piston rod seal (3) is arranged, and wherein each piston rod subpack (1a, 1b, 1c), at least one connection end face (1d) with connection points (2c, 2d), the connecting points (2c, 2d) fluid conducting manner to the connecting channels (2f) are connected, and wherein the connecting points (2c, 2d) in such a way to the connection end face (1d) are arranged, that two successively arranged following one another at their connection end faces (1d) piston rod portion packs (1a, 1b, 1c) via the connecting points (2c, 2d) being conductively connected to one another mutually fluid.
