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