Abstract
A compensator 11 comprises a housing 14 and a sliding ram 13, which is displaceable along a sliding seat 17. The sliding ram 13 includes a flow channel portion 21, which transitions into an elbow bend 30, which, in the operating state, i.e., when hot polymer melt flows through the compensator, is congruent with a further flow channel portion 20. The two flow channel portions 20, 21 have flanges 28 and 29 at their end faces for the installation of the compensator 11 at a bend in a melt line through which a polymer felt flows, to compensate for linear expansions of the melt line due to the increased temperature.
