Abstract
A direct acting release cap for air brake control valves in trains which will allow for the manipulation of the valve characteristics from a direct brake release to a graduated brake release without removal of the cap from the body of the valve. This is accomplished through longitudinal movement of a spool, which directs internal air passages that control valve characteristics. The present invention eliminates the requirement of removing the direct acting release cap from the valve in order to change the working characteristics of the valve, thus resulting in a time savings for the operator.
