Problems solved by technology

Its disadvantage is that after braking, there is always a certain amount of residual air in the air supply port and in the brake chamber that cannot be discharged.
Seriously lead to the inability of the entire braking system and the synchronous valve to work safely and reliably

Abstract

A synchronous valve for brake system has a valve body with air inlet, air outlet and control opening, an air inlet valve in said air inlet and opened when the car is running, a piston in said controlopening for controlling said air inlet valve and several sealing rings. Said piston has an internal air channel for exhausting the residual air from braking tube, a screw plug for regulating its top limit position, and a restoring spring under its bottom.

Description

technical field [0001] The invention relates to a synchronous valve for a vehicle braking system, in particular to a synchronous valve for a heavy-duty vehicle braking system. Background technique [0002] As we all know, the shortcomings of the braking system of heavy-duty vehicles, especially tractors, are that due to the length of the vehicle body and the length of the braking system pipeline, the brakes of the front, middle (rear) cars and trailers are not synchronized, and the braking distance is long. , Brake lag, serious can lead to the tragedies of vehicle overturning, car crash and death, bring immeasurable loss to life and property. Chinese patent CN89108201.8 discloses a vehicle air brake system and its valve, in which a synchronous valve is disclosed, which has an air supply port, an air supply port and a control port. There is a synchronous piston sleeved with a return spring in the cylinder body at the control port, and the lower end of the synchronous piston ...
