COMBINED CYLINDER OF WORK BRAKING MECHANISM AND BRAKING MECHANISM WITH SPRING-TYPE POWER ACCUMULATOR INCORPORATING INTERNAL VENTILATION Russian patent published in 2010 - IPC B60T17/08 B60T13/38 F16D65/32 

FIELD: transport.

SUBSTANCE: invention relates to machine building, particularly to combined cylinders of work braking mechanism and braking mechanism with spring-type power accumulation. Brake cylinder comprises membrane fitted in braking mechanism cylinder barrel and designed to be loaded by pressure, and braking mechanism piston arranged in aforesaid cylinder barrel with spring-type power accumulator. On the one side, said membrane constricts braking mechanism chamber that can be loaded by working pressure and, on the other side, is constricts that chamber that receives return spring. Piston, on the one side, constricts braking mechanism chamber with spring-type power accumulator and, on the other side, it constricts spring chamber that receives spring-type power accumulator. Piston incorporates piston rod with air release valve. The latter serves to create or cut off one-through communication between spring chamber and braking mechanism chamber. Air release valve comprises piston housing the valve body arranged to shift axially in cylinder arranged on piston rod. Compression spring resting upon said piston loads valve body in direction towards first seta of the valve and in direction to second valve seat on the cylinder. Valve body forced from first valve seat and/or second valve seat provides for flow passage between chamber of work braking mechanism and spring chamber.

EFFECT: expanded operating performances.
