This EN standard considers one or more input pressures in accordance with the diagram in Figure 1. 3.1.2 input pressure control pressure received by the

35、e brake cylinder pressure when the relay valve is used in a variable load braking system. This pressure can also be used as the input pressure to another relay valve. The output pressure can obtain one, two or three fixed levels or it can be changed continuously between a minimum and a maximum or vi

42、nal is used to change the ratio 3.1.6.4 multi stage variable load relay valve relay valve type C1 relay valve with a continuously changeable relay valve ratio, where a load signal is used to change the ratio and with a multi stage feature added NOTE Typically a load signal is used to change the rela
43、y valve ratio and a control signal (automatic or manual) is used to change the stage(s). The typical result is that at the same load and input pressure, in the lower stage (e.g. P-mode, passenger train) results a lower output pressure and in a higher stage (e.g. R-mode, rapid passenger train) this r
