Railway truck frame mounted load weigh valve

摘要

A load weigh valve assembly for a railway car is provided. The load weigh valve assembly is mounted to the truck frame on primary sprung trucks to enable actuation of the load weigh valve pivot arm. The load weigh valve assembly is also mounted to the truck frame so as to eliminate the problems associated with oscillating and sliding motion at the load weigh valve pivot arm. In addition, the undesirable valve actuation that occurs due to car roll is eliminated.
