摘要：This invention relates to an electro-pneumatic self-lapping unit of a brake valvefor use on a railway locomotive to effect control of the pressure in a train line pipe byeffecting appropriate energization and deenergization of release and application magnetvalve devices provided on the locomotive and each car in a train for supplying fluid underpressure locally to the train line pipe and releasing fluid under pressure therefrom. Theenergization and deenergization of these magnet valve devices is controlled via trainwires by mechanically actuated switches selectively operated substantiallysimultaneously with the self-lapping unit on the locomotive to supply fluid underpressure to or release fluid under pressure from the train line pipe in response to theengineer effecting manual rotation of a handle mounted on the same shaft as a cam therotation of which controls operation of the self-lapping unit.
