ABSTRACT:
The present invention concerns automatic fluid brake devices in which the fill and discharge of the brake cylinder or cylinders of the equipment are controlled by a device functioning as a distributing valve in relation to pressure variations in the brake pipe.
In the aforementioned automatic braking devices generally used for rail vehicles, and commonly known as distributors, the brake cylinder pressure obtained during the braking process is a function of the pressure in the brake pipe.
The present invention concerns distributors of the graduated release type, in which brake release is not only initiated via pressure increase in the brake pipe, but it is entirely a function of the pressure increase in this brake pipe.
More specifically, the present invention concerns the type of graduated release distributor in which the discharge is adjustable, and the brake is inexhaustible regardless of the manner in which the valve is manipulated by the engine driver to carry out braking or brake release.
