Abstract
In a stripping arrangement for preventing liquid from penetrating at the peripheral gap ( ) between a reciprocating component ( ) and a casing opening ( ) surrounding the latter, a choke ring ( ) is provided on the side facing the inlet of the liquid to be stripped in the stripping bushing ( ) in addition to at least one stripping ring ( ) arranged in a stripping bushing ( ), wherein this choke ring is designed with a smooth annular surface ( ) on its front side facing the inlet of the liquid, and adheres to the smooth inner front surface ( ) of the stripping bushing ( ) facing it, exposed to the adhesive forces (S ) in the liquid. In this way, a significant path of entry for the liquid to be stripped into the stripping bushing ( ) is blocked, so that the stripping ring ( ) has to strip substantially less liquid from the reciprocating component ( ).
