FIELD: railway transport; passenger cars. SUBSTANCE: pneumatic brake system has air distributor 1 communicating with additional reservoir 2. Main line branch of air distributor 1 communicates with brake main line 4 through shutoff valve 3. Output of air distributor 1 is coupled with one of inputs of standard selector valve 5 whose other input is placed in communication with electric air distributor 6 supplied from additional reservoir 2. Locking valve 7 is connected with main line branch of air distributor 1 through its supply input 8. Control input 9 of locking valve 7 is connected with supply input 8. Output branch 10 of locking valve 7 is coupled through additional selector valve 11 with brake cylinder 12. Other input of additional selector valve 11 is connected with output of standard selector valve 5. Offered brake system, as compared with known system of passenger car brakes, features improved safety owing to direct application of pneumatic brake at service braking and use of standby direct acting pneumatic brake which automatically comes into operation in case of failures of standard air distributor at discharge of brake main line by value of full service braking. EFFECT: enhanced efficiency of brake system owing to provision of inexhaustibility of brake cylinder at full service braking in case of failure or cutting off of electropneumatic brake. 2 cl, 1 dwg |
