BRAKE CHAMBER WITH SPRING POWER ACCUMULATOR Russian patent published in 2019 - IPC B60T13/36 B60T13/38 B60T17/08 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Braking chamber comprises working braking section and spring power accumulator section separated by diaphragm or piston to discharge and spring cavities. Spring power accumulator section is equipped with bypass valve arranged in pusher, which is binding device, by means of which spring cavity of power accumulator is communicated via injection section of working braking section and pneumatic system of vehicle with atmosphere. Bypass valve is equipped with seal arranged in valve body from pressure spring cavity section of spring power accumulator, wherein sealer is pressed to thrust washer, fixed in housing, spring, put on cylindrical rod, passed through central hole in sealing element, seal is equipped with external acute-angle locking edge tightly fitting inner cylindrical surface of valve body, and is equipped with end face for interaction with thrust end of movable shutoff element.

EFFECT: higher reliability of locking the pressure cavity of the working braking section and the spring cavity of the spring energy accumulator section and improvement of the brake chamber operation reliability.
