The first stage engine braking
Increased discharge equalizing reservoir in this case (the normal discharge of 0,6-0,7 kg/cm2) is required for activation by inhibition of the wound and the establishment number 254 in the brake cylinder pressure is 0.5 kg/cm2, sufficient to compress the spring brake ottormazhivayuschih cylinders and pressing pads. With a low level of pressure from the diffuser, included in the empty mode, acting on a piston valve number 254 (0,5-0,7 kg/cm2), enough to open the valve 2, downforce springs 3 and the pressure of the nutrient line from the cavity 4, and the creation of pressure under the piston 1iv brake cylinders more than 0,5 kgf/cm2.
