Cars with diffusers № 292
The presence of a passenger train car with the diffuser № 292 improves the operation of the triple valve discharge due to service additional line produced by these diffusers. In the accelerator-off rate and an emergency braking at the head of the main pistons valve train will move to position emergency brake and brake cylinders will be filled to a pressure of 3,7-3,8 kg/cm2 (through a calibrated orifice in the piston accelerator) slowly over 13-15 with . At the same tail of the train brake cylinders will be filled to a pressure of 20-25 sec. At the same trunk pistons will be in the position of the service brake, as the rate of reduction of line pressure does not reach the emergency rate.
