RAILWAY VEHICLE BRAKE AIR DISTRIBUTOR Russian patent published in 2016 - IPC B60T15/18 B60T13/26 

FIELD: machine building.

SUBSTANCE: invention relates to railway transport. Air distributor includes a housing in which there are three pressure elements, element of two pressures and two-chamber reservoir with chambers and channels for communication with brake line, standby tank, brake cylinder and elements of three and two pressure values. In housing body of two pressures is softness, including guide sleeve, in which a rod spring-loaded valve. In housing body two pressure channels are made for direct communication over movable partition with working chamber. In body of two pressure there is a check valve, which includes an elastic diaphragm in form of a plate and installed on stop in the form of a cylinder with two truncated perpendicularly to base surfaces and spherical ledges on bases. Elastic diaphragm element two pressure device softness, check valve and sealing elements are made of elastomeric material containing polymer composition, resistant to temperature variation in range from +60° to -60°.

EFFECT: higher reliability of device is achieved.
