Latest Patents

Lehnert holds a patent for a "Brake cylinder with built-in slack adjuster." This invention includes a brake cylinder device designed for railway vehicles, featuring an automatic slack adjuster. The device also incorporates a manually axially positionable piston, which allows for resetting the piston and piston rod relative to the slack adjuster when necessary. This is particularly useful during the replacement of worn brake shoes. The piston rod is interconnected through a nut and screw, friction clutch, and a key to a manually rotatable member. When this member is rotated, it causes axial displacement of the piston rod and piston to the desired adjusted position relative to the slack adjuster.
