SLACK ADJUSTER FOR HYDRO-PNEUMATIC BRAKE UNIT HAVING AUTOMATIC AIR BLEED

摘要

A slack adjuster device for hydro-pneumatic railway truck-mounted brake units having the slack adjuster mechanism mounted in a vertical disposition relative to the brake unit to provide vertical gravitational flow of fluid from the hydraulic fluid reservoir to the pressure side of the hydraulic piston during the return or release stroke of the piston so that any air inadvertently present in the hydraulic fluid chamber on the pressure side of the hydraulic piston may flow vertically upwardly and escape via an air vent in the hydraulic fluid reservoir.
