摘要

The adjustment (17) for a pre-loaded spring (13) inside a brake cylinder housing (2) has a first thrust piece holder (18) in the form of a ring fixed towards the longitudinal axis of a brake piston (15), and a second thrust piece holder (20) movable towards the longitudinal axis from outside the brake cylinder housing. The spring rests against a first (14) and second (21) support surface. The second support surface is on the second thrust piece holder.
