ABSTRACT
The article presents the description of the cylinder relay valve designed and made by the Rail
Vehicles Institute "TABOR". The individual components of its construction were
characterized and it was selected those that have the significant influence on change of
resistances to motion of the relay valve. The currently applicable criteria concerning the
operating parameters of the cylinder relay valve are presented. The selected results of the
tests which consisted in determining the impact of resistances to motion on change of the
hysteresis values and the correctness of operation of the relay valve are presented. The stand,
on which the simulation tests of relay valve operation were carried out, and the stand for
measurements of resistances to motion are shown. The article also presents a computer
simulation model in which the results were verified.
