The piston can go no further be-cause the pressure on its two sides areequalized and the small piston is heldto the extreme left of its travel by thebrake cylinder pressure on the brake-pipe or atmospheric pres-sure is on the left. This is the condi-tion and position of the parts shownin Fig. 7. With all passages and spaces equal-ized in this way and the brake-pipeclosed to the atmosphere, the triple isready for an increase of brake-pipe■ and the release of the brakes.
