초록 ▼

Electro-pneumatic brake apparatus for railway vehicles including a dynamic brake portion and a fluid pressure operable brake portion both of which are actuated by a common variable signal which produces a corresponding control pressure for effecting operation of said fluid pressure operable portion, such control pressure also being simultaneously converted to an electrical control pulse for effecting operation of the dynamic brake portion at the same time as, or at least not ahead of, the fluid pressure operable portion. The apparatus is further provided with a combined electro-pneumatic monitoring device for determining the sufficiency of the combined brake application.
