ABSTRACT:
For use, for example, in an anti-theft device having a lock, a piston moves in a cylinder having variant bores which provide upper and lower tapers. During factory assembly, a soft metal liner is deformed upon such tapers whereby to prevent, during later operational use, unwanted leakage of a pressure fluid either within or to the outside of the piston-cylinder assembly.
