ELECTROPNEUMATIC VALVE FOR AUTOMATIC BRAKING Russian patent published in 2008 - IPC B60T15/36 B60T13/68 B60T7/12 

FIELD: transport.

SUBSTANCE: invention pertains to railway transport, and particularly to braking systems of railway vehicles. In the chambers of the pneumatic repeater of the electro-pneumatic valve for automatic braking there are pressure sensors, the outputs of which are joined to the input device of an electronic microcontroller. The data from the microcontroller is used in the functioning of the valve of the stepped service brake application for generating the corresponding output signal of the microcontroller on the control channel for the electromagnetic valve for changing pressure in the control chamber of the repeater. The need for such a type of braking is processed by a microcontroller with consideration of data from other sensors and devices, providing for safety of the locomotive. During emergency braking with use of the given electromagnetic valve for carrying out functions in the given time interval after the warning signal has been given, the same microcontroller is used, allowing for giving the required value of this interval. The device for giving the warning signal is also controlled by the same microcontroller, through opening of the corresponding electromagnetic valve, linked to the device for giving the warning signal and the supply main line.

EFFECT: wide range of technical capabilities with simultaneous lowering of materials consumption of the product.
