BRAKE CHAMBER WITH SPRING-LOADED 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 with spring-loaded power accumulator comprises section of working braking and spring power accumulator section separated by diaphragm or piston at discharge and spring cavities. Spring power accumulator section is equipped with bypass valve arranged in pusher, which is coupling 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. Cylindrical surface of the shut-off element is conjugated with the conical surface of the blind central hole along the cone generatrix, made on its end from the bottom of the valve body, wherein outer cylindrical surface of locking element is not conjugated with inner cylindrical surface of valve body.

EFFECT: ensuring reliability of the device, possibility of balancing pressure in the spring cavity of the power accumulator with atmospheric pressure through the pneumatic system of the vehicle.
