Its construc-tional features are quitesimilar to those of theplain triple valve, one ofthe noticeable differencesbeing that the operatingpiston and slide valveoccupy a horizontal posi-tion, while in the plain triple valve they have a vertical also differs from the plain triple valve in having additional quick- Fig. 41.

This triple valve is arranged so as to bebolted to the pressure head of the brake cylinder in passengerequipments or to the cast-iron auxiliary reservoir in freight equip-ments, thus making the brake-pipe connection the only pipe con-nection necessary to the triple valve.
