摘要

Protection device against overpressures that take place in the compressed air brakes completely loose and provided with a three-way valve for pressure, which are used, especially in the vehicles on rails, when the brakes are completely loose, which it combines the following features: a) a monitoring device that is interposed in the air supply duct, namely, between the main air pipe and the constant pressure distribution chamber belonging to the three-way pressure distribution valve, and having the mission to throttle or close said duct, once it occurs, while the brakes are loose, a load shock, which occurs during a limited period of time or during the overpressure effect; b) a monitoring device that interrupts the feeding of the brake cylinder, regardless of the pressure that is present at the moment in the auxiliary air device, once the maximum regular pressure in the brake cylinder has been reached, or chokes or closes, during the time mentioned under a), the supply of the auxiliary air tank.
